E S P E C I F I C A I N The present invention has as an objective an auxiliary suction device arranged in the field of hydraulic pump equipment and which was developed and combined to make the liquid pressure, preferably water, more efficient. There are certain hydraulic pumps for pressure or for other liquids in a tank which, despite their efficient work, have the disadvantage of having the water tanks located in the upper region of the casing, whereby the water tanks are located at a certain level. height in relation to the bottom of the tank and because of this, the water being below the water tanks is not taken. A pump like this is substantially formed by a housing, which houses an axial and oscillating element, whose lower end is supported by a solenoid, the intermediate region of that element has a central membrane region, peripherally seated on the housing on its wall and with that, a pressure chamber, with upper outlets in the form of an inverted "Y" that form the opposite upper extremity of the element and has a seated closed cup that opens and closes a communication passage between the pressure chamber and an entrance chamber, which communicates to the media, from which the water is pumped through an inlet valve, constituted by water tanks. In order to overcome this problem, the auxiliary suction device is practically formed by a bell-shaped vase with a height -sufficiently larger than the pump body and exposed to the interior, this bell-shaped vase is formed in the upper surface with a central hole through the pressure of the pump; the side wall which is in connection with the external surface of the pump, defines an auxiliary annular suction chamber and at the lower end of the said bell-shaped vessel, a mouth is opened defining the inlet of the suction chamber - annular and from which a column of water forms around the pump and up to the water tanks; the mouth is sufficiently below the lower extremity of the pump, a little above the bottom of the reservoir and supported by brackets, where the -shorts are defined. The evolution of the studies related to the use of the assembly formed by the hydraulic bonba and the auxiliary suction device as described above, led to more practical and -effectively understood arrangements, basically by using the pump at the highest position relative to the bottom of the tank and mounting the pump in this position, into the auxiliary external pressure chamber in relation to the pump, with a communication opening with the reservoir and where the water tanks of the pump are exposed, supply the pressure output of the pump and provide the referred pump with new pressure outputs that are connected to the pump. n with the inside of the external auxiliary pressure chamber and still provides a pressure output that couples with the pressure line. Thus, in the case of the pump previously described in particular, when used in accordance with the present arrangement, it is exposed in an inverted position, that is, with its upper surface having water tanks turned downwards and no - pressure drop in the form of an inverted "Y", as well as - being assembled at the bottom of the pump and still providing the mentioned pressure chamber of the pump with radial openings that are in communication with the inside of the chamber external auxiliary pressure and the chamber has its pressure outlet located at the upper extremity. With these provisions given to hydraulic pumps with high water tanks, particularly the pump that has been described here before, the entire volume of water in the tank can be exploited and -pressurized avoiding the drawbacks that have been mentioned. previously. In a preferable construction, --- the inlet valve of the pressure pump, previously described, is formed by a general direction that connects the inlet chamber with the medium from which the liquid is pressurized, this general direction is assembled in the wall of the inlet chamber, obtained from a resistant abrasion material and comprising a central hole surrounded by other peripheral holes exposed in a circumferential alignment and regularly spaced to the receiver of a central fixing bolt in a flexible membrane , whose periphery is exposed on peripheral rollers and act on them as valves of the half-round type, that is to say, they open and close said orifices due to, respectively, the depression and pressure of the inside of the cap. -1 entrance chamber, made by the mejí cupped vessel donated during the period in which the pump is working. Due to the good working of the inlet valve according to the aforementioned construction, problems can not be attributed to it and nothing prevents it from being the best way to work and the pump to which it belongs. Therefore, when the pressure output is presented under counter pressure of the column of the liquid (water,) and the container, from which the pressurized water is emptied and has its level under the water tanks, the air inlet in the chamber - inlet is favorable, which demands pos - post air work and prevents the movement of the vase acroddo, which opens and closes the passage between the entrance chambers and the pressure, to create depression at the inside of the inlet chamber at a level sufficient to open - the inlet valve, that is, to bend the valve membrane in order to open the holes of the water inlet that interrupt and in this way the pump is pumped of the bomb. In order to overcome this problem, the improvements in the input sets were developed, of the inlet chamber, with one or more orifices of purging the air of the valves with conformation and disposition in the membrane or appropriate walls to be closed or opened through the compression or decompression of the inlet chamber of the inlet chamber. the separation of the liquid medium that deals with the pump and by the flexibility of the material of the membrane or the flexible plug that contains the valve orifices and that is assembled in the hole in the wall of the chamber. This form of construction of the input socket solves the problem that can be seen - usually in the conventional input assembly and, consequently, in the pumps that use the same assembly, once it is placed inside the chamber and the pump begins to work, the aforementioned cup that commands the communication between the input chambers and the pressure, on the first movements forces the air contained in the inlet chamber to circulate outwards through the valve purge orifices, from which the entire inlet assembly and pump begins to work normally. The appended drawings show the improvements in a hydraulic suction auxiliary device and in the input assembly, the objects of the present patent. In the drawings: Figure 1 shows a pump of the type in which the auxiliary suction device is applicable which can be used according to the present patent arrangement and wherein the improved input assembly takes part of the conventional construction and with a partial cut. Figure 2 shows the auxiliary suction device in a dismembered perspective. Figure 3 shows the device assembled with pump and cut. Figure 4 shows a detail aj? plified from the cut of the previous figure. Figure 5 shows a hydraulic pump constructed with the facilities, object of the present patent. Figure 6 shows a detail of the previous figure. Figure 7 shows an enlarged and u-cut detail of the improved input assembly, in that position where the inlet valve closes the water inlet to the inlet chamber and opens the outlet for the air eventually contained in the air inlet. inside the entry chamber. Figure 8 shows the external detail but a position in which the inlet valve opens a passage to the water inlet in the inlet chamber. Figure 9 shows the same view as Figure 7, but a position in which the inlet valve closes the water inlet and air outlet, which does not exist inside the inlet chamber. Figure 10 shows another possibility of construction of the improvements on the inlet assembly, in the position that closes the water and closes the -exit of air eventually lodged in the intermediate region of the inlet chamber. Figure 11 shows the assembly in a position in which the inlet valve opens - the water inlet; and Figure 12 shows a similar view to Figure 10 in a position in which the valve closes the water inlet and the air outlet, which does not exist inside the inlet chamber. In accordance with that in which the appended figures are attached, the installation of the auxiliary suction device in hydraulic pump and inlet valve object of the present invention is used in a hydraulic pump (FIG. 1) of the practically formed type. % with a housing, (1) containing an axial oscillating element (2), whose lower end is supported by a solenoid (3) and intermediate to the element has the central region of a flexible membrane (4) assembled, whose pe riferia is assembled in the wall of 1 housing and defines a pressure chamber 5 in the form of "Y" inverted in the outlet (6) and at the upper end of the oscillating element (2) are mounted a cup 7 in the form of a cup, East # commands the opening and closing of a communication passage 8 between the pressure chamber 5 and an entry chamber 9, this communicates to the means or reservoir from which the pumped liquid is pressurized through the valve = which defines the water tank 11, which is at a height "H" in relation to the bottom 12 of the tank. The auxiliary suction device used with the previous pump, is formed practically, a cup-shaped vessel, (figures 2 and 3) -substantially higher than the pump (1) of the body and inside which is mounted axially and suspended this bell-shaped vessel has an upper wall with a central hole 15, which is transverse and has the pressure outlet (6) of the pump mounted and the upper wall protrudes a side wall that defines in collaboration with the surface external of the body of the pump (1) an annular suction chamber (17) and inside the bell-shaped vessel 13, has a mouth (18) that defines the entrance to the suction chamber (7), from from which an "A" column of water forms around the pump to the water tank; the mouth 18 is below the lower extremity of the body of the pump 1 and raised in relation to the bottom of the tank by means of brackets (19) mounted on the cup in the form of a -campana, through which the passages that can communicate with the pump (18) of the suction chamber (17) and that remain resting on the bottom 12 of the reservoir. In a preferred construction of the auxiliary suction device, the bell-shaped vessel 13 is formed by two parts, namely: a part of the upper bell-shaped vessel (20) and a lower bell-shaped vessel part ( 21), which has the * upper surface (19) provided with an orifice (15) - central that receives the pressure outlet (16) of the pump, which is mounted in the central hole by means of a fixing impediment and insulation device (22) - adjacent to the ends of both parts of the bell-shaped vessel are provided with respective external flanges' J_23) and a connecting ring (24) is mounted on the upper (20) and lower (21) parts of the bell-shaped vessel and has the lower suction mouth (18) in the form of a grill around which a ring (25) having the brackets incorporated (19) is assembled; the device (22) for fixing and insulation of impediment, the ring (24) of intermediate connection and the ring (25) having the brackets incorporated and even the brackets (19), are obtained from flexible material, preferably from rubber which, together with the fact that the bell-shaped vessel is constructed in two parts, acts in such a way as to prevent the propagation of the vibration of this pump (1) towards the auxiliary suction device and from from this to the deposit, in order to avoid the inconvenience caused by these vibrations. The impeding isolation and fixing device (22) rotating on the pump '(1) and the bell-shaped vessel (13) (Figure 4) is comprised of a bushing (26) of flexible material which is the center of the upper hole (15) of the bell-shaped vessel - receives the pressure outlet (6) of the annular pump and bearing (27) of flexible material mounted around the pressure outlet (6) under the bushing (26) ) and between the upper surfaces of the pump body (1) and the bell-shaped cup (13) and respective fixing device (22) can be completed by means of an external metal retaining ring (28) which can be externally mounted on a hub piece (26) projecting outward from the upper hole (15) of the bell-shaped vessel, the retaining ring is provided with longitudinal cutouts (29) defining parts (30), which can be compressed against the bushing (26) and from the retaining ring (28) protrudes superiorly and axially a peak (31) with a stepped external surface and in which the pressure pipe 32 is in reduction or amplification coupling, i.e. it is maintained with the brackets (33) and also being able to be fastened, without damaging the work of the suction element, to the pipe of pressure directly towards the - outlet, when it is done in common pumps, of the same type. The connecting ring (24) is formed by an annular body of fl exible material and a square section (34) that from the inner surface in the middle piece is bent to one edge. (35) surrounding orthogonal and from the corners of that internal surface curved to shorter and measured shores (36) having initial and thick prismatic pieces (37), which in collaboration with the central bank (35) define the gutters ( 38) said central edge (35) is between the flanges (23) of the parts of the vessel (20) in the form of an upper and lower bell (21) in order to grant a perfect stabilization thereto.; the gutters (38) receive respective prismatic ferrules (32) placed on the free end of the flanges (23) and the final measurement pieces of the edges (36) stop on the surface of the respective flanges' (23) of the parts of the bell-shaped vessel (20) and (21). The lower ring (25) of the lower part of the cup (21) in the bell frame has been fixed in respective holes (41) around the mouth (18) of the bell-shaped cup; the outer edges of the ring, have their edges (42) turned upwards which are adjustable to the external surface of the vase in bell form - the mouth (18) of the lower surface mentioned are assembled in the brackets (19). Preferably, the lower parts of the upper bell cup (20) and lower bell (21) are configured conically provided with plastic material. So, when the whole set? By the pump (1) and the suction auxiliary device is immersed in the water, the suction chamber (17) between the configured vessel (13) and the pump body (1) is filled. In the event that the water level is higher than the water reservoir (11) of the pump, it works normally. However, when the water level * is below the level of the water tank (11) of the pump, the vacuum formed on the water sheet inside the suction chamber (17) allows the formation of an "A" column of water between the sheet ( 11) of water that guarantees the normal work of pumping, until the entire deposit is drained. Even if the water column is not done when the pump is turned off, the pump will work # normally again when it is turned on, once the vacuum formed on the sheet of water and inside the suction chamber (17) causes the water to come back to the water reservoir (11) of the pump, until there is no more liquid to drain from the sepdsito- As already seen, in the normal position of the pump, the water tanks are exposed to a height "H" from the bottom (12) of the tank of water or other liquids , in this way, it is not usually able to handle the complete water or the liquid that is kept in the tank, that is, the water or the liquid that is below the "H" position. Consequently, the arrangement in the hydraulic pump, object of the present invention, is to generically expose the pump in a position in which the water tanks (11) are at the minimum height (H) possible relative to the bottom of the reservoir, the pump thus exposed, inside an external auxiliary pressure chamber (100), provided with the openings (101) opens into an external auxiliary pressure chamber (100), provided with the opening - (101) open to the inside of the tank and where the above-mentioned water tanks' (11) of the pump and with new pressure outlets (102) are. assembled by connecting to the interior of the pressure chamber (100) referred to external auxiliary provided with the opening '(101) open to the interior of the tank and where the referred water tanks (11) of the pump, with new outlets - (102) ) of pressure, are assembled by connecting to the interior of the re-feridated external auxiliary pressure chamber (100) and finally, provide this final pressure output (103) that is coupled with. the pressure pipe. Consequently, when this provision is applied to a pump with the characteristics of »The one illustrated in the figure and previously described, this pump is used in position (figure 5), that is to say, with its surface normally superior (104), which has the water tanks (11), turned towards the bottom side and without the exit of pressure (6) in the form of "Y" inverted, as well as assembled in the bottom is provided with a central opening (101) that houses the water tank (11) of the pump, and opens in the direction to the external side of the external auxiliary pressure chamber (100) and still, the present arrangement consists of providing the pressure chamber (5) of the radial pressure outputs of the pump (102) with a connection with the inside of the external auxiliary pressure chamber (100) and at the end of the pressure outlet (103) of the latter, is placed on the extremity of the external auxiliary pressure chamber (100) turned upwards and in a manner that receives to the pressure pipe. In a preferred construction of the external auxiliary pressure chamber (100) this is provided by two chamber pieces in conical shape, one upper (106) and the other lower (107), with one having the upper surface with one outlet (103) of centrally exposed pressure, between the part of the lower chamber (102) that has assembled a lower ring (108) that serves as a support base of the assembly, having centrally the opening (101) of entry that houses the deposits (11) and has peripheral brackets (109) that keep a little exposed on the bottom (12) of the tank and still the larger adjacent ends - of the upper (106) and lower (107) housing are - provided with a flange ( 110) external circuendante - which is joined by a ring of union and obstacle - intermediate. The intermediate connecting ring (111) (Figure 6) is formed by an obstacle ring of a flexible material (112) which is interconnected between the flanges (110) of the housing parts (106) - and (107); a union ring with a "C" section and resistant to deformation of the material (113) is externally coupled to the flanges (117) and an external obstacle ring with a C-section and flexible material (114) is externally coupled with the connecting ring (113) and against the surface of the housing and the obstacle ring (112) interlocked with the flanges (110) has its edges - turned towards the inside of the chamber provided with a border (115) in cross-section and together with the outer obstacle ring (114), preferably rubber or the like, while the connecting ring (113) may be formed, for example by metal or other non-deformable or easily deformable material . In another construction possibility the external auxiliary pressure chamber, not illustrated, may # to be formed by a cone-shaped lower part (107) and replace the upper part (106) as? a cube, having the central opening towards the pump with the turned-up end, capable of crossing, naturally provided with pressure outlet and convenient obstacle. The inlet valve 10 (FIGS. 8, 9, 10, 11 and 12) previously rotated, is usually constituted by a rigid seat (200) which, assembled in the wall defining the inlet chamber 9, provides an orifice ( 201 central) surrounded by peripheral holes (202) aligned circumferentially and for the case of water and regularly spaced; the hole (201) detects and fixes a central seating pin (203) of a flexible command membrane (204) which is exposed on the face of the seat (200) turned towards the interior of the entrance chamber 9 and whose periphery it is on the mentioned peripheral holes (202) of the water passage and on the external face of the seat (200) there are openings (205) for the assembly of the inlet valve in the pump. The present improvement consists of providing the inlet chamber 9 with an opening with a purge air valve 206 and by 2061 constructed and exposed in such a way as to close and open automatically. • by means of the pressure and depression of the cup 7, as well as by the liquid handled by the pump and by the flexibility of the material in which the relief hole purges the air 206 and / or 2061. In a first construction - the valve orifice of the purge air 206, designed to purge the air eventually contained in the upper region of the chamber 9, as in figures 7 to 9 - the orifice The air purge valve valve 206 is axially e_x placed on the command membrane 204, extended from the outer face of the upper part 207 of the seat bolt 203 since it corresponds to the opposite region 208 of the inner face of the membrane; the internal opposite region 208 is radiated by an annular articulation groove 209 and in that region 208 'a valve 210 is incorporated, formed by a conical point constituted in the referred internal region 208, whose top opens towards the inner extremity 212 of the air-purge valve orifice 206 and on that top there is a metal cutout 213 with a V-section passing through the aforementioned internal end 212 of the air purge orifice-206, thus constituting lips that open and - they close the end of the internal hole 212, by means of the compression and decompression of the interior of the inlet groove 9 made by the movements of the cup 7, as well as by the liquid handled by the pump and by the flexibility of the membrane 204 'decorating acting together. Consequently, when the inlet chamber 9 has an air position in the upper region of its interior and the pump is turned on (figure 7), the first movements of the vessel 7 assembled are in the feeling of compressing the chamber, takes the air that comes out again - instead of the air purge valve orifice 206 of the inlet chamber 9 and in this way, the liquid is pressurized by the pump and the assembly works normally, (figures 8 and 9). This way of working is due to the fact that there is air inside the inlet chamber 9 and the cup 7 is moved to compress the chamber, as can be seen in figure 7, the air prevents the pressure and the liquid closes the lips 210 of the valve # and the referred air simultaneously forced by the pressure rotates through the purge valve orifice 1 - (dotted lines of figure 7) out of the inlet chamber 9, thus making it possible to work normally. On the other hand, when there is no air inside the inlet chamber and the cup-shaped chamber, as shown in Figure 9, the pressure and the liquid push the valve lips 210 to a position in which they are placed. it closes the valve orifice 206 of the purge, thus avoiding the inadequate leakage handled by the pump which, if it occurred, would damage the work of the pump. In another construction possibility, the air purge valve orifice 206 'designed to purge the air is optionally maintained in the intermediate region of the inlet chamber 9 which is accommodated due to the compression and decompression system On which is assumed in the inside the camera (figures 10 to 12); the air purge valve orifice 206 is radially and externally exposed in the inlet chamber 9 and may be in a number of 1 or more and each is virtually formed by a hole 214 radially in the middle region of the wall 215 of the inlet chamber 9, which receives a corresponding bar of flexible material 216, preferably of rubber or the like, having the orifice ^^ 206 'of purge valve axially exposed and extended from one end 217 of the bar, i.e., externally exposed to the inlet chamber 8 and immersed in the middle - of the liquid that is pumped by. the pump, up to the enlarged opposite end 218 of the bar, which is turned towards the inside of the inlet chamber 9, this enlarged end is not crossed by the end 212 'of the purge drier 206' and comprising a valve 210 'esejí

The latter is formed by a conical tip 211 'folded - to the underside having a sectional transverse cut 213 in "V" passing through the end 212' of the valve purge orifice 206 'and from the closing lips and it opens the end of the internal hole 212 'by means of the compression and decompression of the internal chamber 9, made by the movements of the liquid that is handled by the pump and by the flexibility of the bar 216, which act together. The purge valve orifice 206 radially exposed in the inlet chamber 9 works exactly like the air purge valve orifice 206 of the membrane 204, as described above but acts more effectively to purge the air housed in the intermediate region of the chamber and confined to half the liquid kept in it. to ?
