Definitions
- the present invention relates to the field of jet pumps.
- the present invention finds in particular, but not exclusively, application in the field of tanks motor vehicle fuel.
- the present invention can find application in fuel transfer between different pockets for fuel tanks multipockets, or for filling a reserve bowl which draws a fuel pump or any other fuel supply device.
- suction devices from jet pump fuel are shown in the documents DE-A-3 915 185, DE-A-3 612 194 or DE-A-2 602 234.
- document DE-A-4 201 037 proposes to arrange inside the nozzle, in upstream of the outlet nozzle thereof, a plunger core carried by a spring-loaded membrane, so that the plunger retreats in the event of an increase in pressure to increase the free section of the nozzle of the nozzle.
- document DE-A-4 201 037 proposes to make the very body of the nozzle in the form of a deformable element with respect to a plunger core fixed again to adapt the outlet section of the nozzle at the injected pressure.
- Document DE-U-9101313 describes a jet pump for transferring fuel to a fuel tank motor vehicle fuel comprising a cap of conical shape mounted with displacement opposite the main nozzle outlet nozzle and downstream of it.
- the present invention now aims to offer a new and improved jet pump.
- the core is provided with a channel longitudinal through forming an auxiliary nozzle.
- the operation of this alternative embodiment will described later.
- FIG. 1 a pump to jet according to the present invention comprising a cylinder housing 10 centered on a longitudinal axis O-O.
- This box 10 defines a control input 12 receiving the injected flow, at a first end axial.
- the axial output 14 of the pump is defined at the opposite axial end.
- the housing 10 also has an input suction aid 16 which communicates laterally with the internal channel 18 of the housing 10.
- This auxiliary suction input 16 is located near the control input 12. It can be formed by tubing inclined with respect to the axis O-O of the case, for example from an angle included between 10 ° and 90 °.
- the housing 10 has at the entrance 12 a sprinkler 20. Thereafter this sprinkler 20 will be called “main” nozzle. It can be a sprinkler reported on input 12 as illustrated in FIG. 1, or a sprinkler integrated by manufacturing into the housing 10 or a section of the housing 10. Of course, a sealing must be defined between the inlet of the nozzle 20 and the input 12 of the housing 10.
- the nozzle 20 is composed of two sections 22, 24 axially juxtaposed.
- the first section 22 in the flow direction is preferably of frustoconical convergent shape.
- the half angle at the top of this section 22 is preferably between 10 ° and 80 °.
- the second section 24 of the nozzle 20 is cylindrical preference of revolution and cross-section constant.
- the free outer end 240 of this section 24 is preferably slightly rounded. We will describe by the following with regard to FIGS. 6 to 9 different modes of realization of such a nozzle end.
- the section right of section 180 of channel 18 formed in the housing 10 is preferably cylindrical of revolution and constant dimension.
- a core 30 is disposed opposite the nozzle outlet nozzle 20, being guided translation, along the O-O axis, against stress a spring 40.
- the core 30 can be guided along the axis O-O by many appropriate means.
- the core 30 is provided with a channel central internal blind 32 opening at its end rear opposite the nozzle 20. Furthermore, the core 30 is engaged, by this channel 32, on a rod 50 centered in channel 18 and connected to housing 10. As an example not limiting, this rod 50 can thus be supported on the internal surface of the housing 10, in the channel of this one, by three fins 52 equi-distributed at 120 ° around the axis 0-0.
- This rod 50 has most of its length a cylindrical section of constant dimension complementary to the cross section of channel 32 formed in the core 30. However, the rod 50 has preferably a tapered tapered rear section 54 or converge away from the nozzle 20.
- the front face 56 of the rod 50 is preferably plane and orthogonal to the O-O axis.
- the face rear 58 of rod 50 is preferably rounded or conical.
- the fins 52 are connected to the part cylindrical of the rod 50, immediately upstream of the transition zone towards the tapered section 54.
- the core 30 has an envelope generally cylindrical outer of revolution and constant section.
- the core 30 however has a front section frustoconical 34 terminated by a front end generally in hemisphere or in warhead 36.
- the nucleus 30 also has a tapered rear section 38.
- the spring 40 is advantageously a spring of helical compression arranged in the channel 32 of the core 30 between the front face 56 of the rod 50 and the bottom of the channel 32.
- the spring 40 urges the core 30 to bear against the nozzle of the nozzle 20, more precisely against the rear surface 240 of section 24 or on a generator contact.
- the core 30 thus preferably rests against the free end 240 of the section 24, in the form of a zone limited substantially to a circular edge or on a contact generator defined at the zone level transition between the tapered section 34 divergent and the front end in hemisphere 36.
- the channel 18 formed in the housing 10 can have a section 181 converging towards exit 14, itself followed by a straight section 182 constant cylindrical.
- the length of the converging section 181 is advantageously equal to the length of the divergent section 34 of the core 30.
- the core 30 is advantageously guided along the axis O-O, at its cylindrical section of revolution, by guide studs 17, for example three guiding studs evenly distributed at 120 °. These are from preferably arranged in the extension of the fins 52.
- the contact area defined between the front end of the core 30 and the outlet nozzle of the nozzle 20 has a limited amplitude.
- the internal surface 202 and the external surface 204 of the section 24 of the nozzle 20 are cylindrical of revolution around the axis O-O, and the end 240 of the nozzle 20 is formed of a cap 208 O-ring, i.e. delimited in cross section by a circular sector, which connects tangentially on the external surface 204 and which joins the surface internal 202 at a circular edge 206, which edge 206 defines the contact at rest with the core 30.
- the angle defined between the toric cap 208 and the internal surface 202, at the connection between these can be the subject of various variants. he is typically of the order of 90 °.
- the second embodiment of the end 240 of nozzle 20 illustrated in FIG. 7 is distinguished from that illustrated in FIG. 6 and previously described, by the fact that the toric cap 208 does not connect on the internal surface 202 in the form of an edge 206 circular, but connects tangentially to a second O-ring surface 210, radially internal, which itself connects tangentially to the surface internal 202.
- the contact at rest between the core 30 and the nozzle 20 is thus defined at this surface toric 210.
- the second toric surface 210, radially internal has a radius of curvature less than that of the O-ring surface 208 radially external.
- the radius of the surface radially external toroidal 208 is of the order of 1 to 2 mm, while the radius of the toric surface 210 radially internal is of the order of 0.05 to 0.5 mm.
- FIG. 8 variant A third is illustrated in FIG. 8 variant according to which a flat surface in crown 212, or if necessary of frustoconical shape, is interposed between the two toric surfaces 208 and 212.
- Figure 9 a fourth variant which differs from that illustrated in Figure 8 by the fact that the surface O-ring 208 radially external is replaced by a chamfer or frustoconical surface 214.
- end 240 of the nozzle 20 can be the subject of many other variations of production.
- the jet pump architecture conforms to the present invention avoids any valve of discharge upstream of the nozzle 20.
- the present invention avoids any loss of return flow, in the form external discharge, so that the injected flow Qi is permanently equal to the return flow.
- the section ejection i.e. the free section of the nozzle 20 is reduced and increases the transmitted power to the jet pump by a high injection pressure Pi.
- the core 30 recedes by compression of the spring 40, with respect to the nozzle 20 which increases the section of passage at the outlet of the nozzle and to limit the back pressure upstream of the nozzle 20 at an acceptable level.
- the flow of the flow leaving the nozzle 20 takes the form of a conical film channeled by the converge on the annular mixer.
- the angle of taper of the section 34 of the core is of the order of 8 °
- of the section 38 of the core is of the order of 9 °
- of section 181 of channel 18 is of the order of 5 °
- of section 54 of the rod 50 is of the order of 6 °.
- This channel 300 can be the subject of various variants.
- the channel 300 is formed of three sections successive, 302, 304, 306, which follow one another from nozzle 20, towards the pump outlet.
- the first section 302 is cylindrical with revolution and constant section. He's stretching typically over 4/5 of the length of the core 30.
- the second section 304 is converging in the direction from the pump outlet.
- the third section 306 is cylindrical revolution and at least substantially constant section.
- the outlet diameter of the channel 300, or the outlet diameter of section 306 (which auxiliary nozzle) is between 0.4 and 1mm.
- the core 30 is guided in translation opposite the nozzle outlet 20 and biased towards this outlet by a spring 40.
- the core 30 can be guided in translation by all appropriate means. According to the embodiment no limitative illustrated in FIGS. 10 to 12, provision is made for this purpose on the internal surface of the housing 10, longitudinal fins 310, for example three fins 310 distributed at 120 °, which in combination define a additional free internal volume of the envelope of the core 30. As a variant, the fins 310 secured to the core 30.
- the spring 40 can take various configurations.
- it is formed of a spiral spring which is supported on the one hand on a recess of the core 30, on the other hand on the upstream end of fins 110 integral with the internal wall of the housing 10, for example three fins 110 distributed at 120 °.
- FIGS. 10 to 12 increase suction performance of the very low flow annular jet pump injected (typically for flow rates below 20 l / h) while limiting the back pressure (or injection pressure) to maximum return flow.
- FIG. 14 a variant with double flow in which the core 30 provided with a longitudinal through channel 300, rests on the outlet of the nozzle 20 via a bearing surface of hemispherical or semi-toroidal geometry (while the bearing surface of the core 30 is generally frustoconical according to Figures 10 to 12); and in FIG. 13, an alternative embodiment which is not distinguishes from figure 14 that by the fact that the channel 300 is obstructed. So the embodiment of the figure 13 corresponds to a simple flow.
- the core 30 is guided by fins 310 as described with reference to FIGS. 10 to 12; and the spring 40 is supported between the core 30 and fins 110 integral with the housing 10.
