Mittelstaedt, 274 '73:51 St., Brooklyn, N.Y. inne Feb. 26, 1962, ser. Na. 175m) 6 eizams. (ei. zse 92) This invention relates to suction means, including suction pumps, and relates particularly to the specific construction of the suction device, that is, the conduit or flow tube and the suction tube associated therewith. The device is capable of independent use, separate and apart from any specific use or any specific source of fluid through the conduit, and may be used wherever suction devices are employed. For instance, the suction device may be used in connection with jet engines and other internal combustion engines, it may be used in combination with any intake or exhaust means, with spray, draining, and draft devices, with aeration devices and other combining devices, to drive turbines or other apparatus, and wherever suction flow is utilized.
Objects of this invention are: to provide a suction pump in connection With fluid flow, to increase the efiiciency of suction devices, to improve suction tubes, to improve suction purnps, to produce suction flow, to augment suction flow to augment fiow in the conduit downstream of the suction pump, to increase the effective total momentum of fluid, to increase the effective total momentum of fluid discharged in unit time, to increase thrust, to increase power, to utilize the suction flow to secure a cooling effect, to drive a turbine, to provide a cool running turbine, sirnplicity of construction, installation, and maintenance, and low cost.
These and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.
The drawing shows sectional views illustrating the invention, but the invention is not limited to the particular examples illustrated.
FIGURE 1 is a longitudinal sectional view of a conduit and a suction tube with a transversal and a peripheral opening extending partly across the conduit, showing an embodiment of tlris invention.
FIGURE 2 is similar to FIGURE 1, but a tube leads from the peripheral opening to the outer end of the suction tube.
FIGURE 3 is a transverse sectional view of the device taken on the line 3-3 of FIGURE 2.
Referring in detail to the drawing, the numeral lt) indicates a conduit or flow tube, and 11 indicates a suction tube with a transversal suction opening 12 and a peripheral suction opening 13. The suction tube extends With all sides about three quarters across the flow tube at right angles to the axis thereof. The size of the suction tube to flow tube is an important feature in this invention, and an extension 3/4 across is necessary to obtain effective suction with this type suction tube. The transversal suction opening 12 is shaped in a slight slant, the side of the suction tube toward the flow extending further into the flow tube than the side opposite the flow. The numeral 14 indicates welds or other fastening means, and the arrows in the tubes indicate the direction of flow. Flow tube and suction tube are the straight line wall type.
In FIGURE 2, the numeral 1'7 indicates a partition, forming channel 18, which leads from the opening 13 to the open outer end of the suction tube 11. It must be noted that any kind of tube may be run from the opening 13 to the outer end of the suction tube.
In the transverse view of FIGURE 3, taken on the line 3-3 of FIGURE 2, the numeral indicates the flow tube, 11 the suction tube, 12 indicates the slanted trans- 3,12%),874 Patented Apr. 21, 1964 ICC verse opening in the suction tube, 13 the peripheral or perimetrical opening, 17 the partition, and 18 indicates the channel leading from the peripheral opening 13 to the open outer end of the suction tube.
The suction tube diverges and then converges transversally, and a constriction of flow is produced which increases to the diameter of the suction tube, and then decreases; Velocity increases and decreases in proportion to constriction of flow. The peripheral opening 13 preferably begins immediately downstream of the greatest constriction of flow and extends toward the rear portion of the suction tube. Since pressure is reduced accompanying increase of Velocity, a low pressure area is produced, and air or other fluid is drawn through the suction tube and the openings 12 and 13 into the flow tube.
The peripheral opening 13 may be formed by cutting away or otherwise eliminating part of the suction tube wall downstream of the greatest constriction of flow. The suction tube may also be cast or otherwise made vvith corresponding openings. The openings may be of any character, shape, or form, and in the text and claims, by opening is also meant plural openings, including slits, perforations, pores, or any other type opening.
The wall portion of the suction tube toward the flow may be streamlined, or be equipped with a fairing, and this is part of this invention.
The suction tube may be fastened to the conduit by any suitable means such as welding, soldering, bolting, cementing, screwing, etc.; or a fitting may be made comprising a representative portion of the conduit and the described suction tube extending thereinto, the fitting being inserted in the conduit or attached thereto by any suitable means. Such means include unions or other coupling means, cementing, soldering, welding, etc. The broken lines 15 and 16 in FIGURE 1 indicate the insertion of the fitting in the conduit.
Exarnples of practical applications of the invention are: 1. Drainage pumps, where the defined suction tube communicates with useless water. 2. Aeration devices, where the defined suction tube communicates with air or other gas. 3. Mixing devices, where the defined suction tube communicates with selective mixing fluid. 4. Spray devices, where the suction means and a suitable nozzle are disposed at the end of the hose or conduit, and where the defined suction tube communicates With fluid material used in the spray. 5. Exhaust aeration pumps for piston type combustion engines, where the device is inserted in the exhaust line or attached to the end of the tail pipe, and Where the defined suction tube communicates with air. 6. Suction pumps for jet engines, Where the defined suction tube may extend (a) across the air intake duct, (b) across the burner or ducted burner, preferably at a point where high Velocity has been reached, (c) across the exhaust tube of a combustion chamber, (d) across exhaust nozzle. 7. Suction pump according to Example 6, where the suction tube is connected with turbine means, the turbine means to compressor means, and where a duct is provided conveying the compressed air to the combustion Chamber. Fuel means and perhaps ignition means may be provided in an optional manner.
I illustrate a conduit and suction tube of the straight line Wall type, and I show the suction tube extending into the conduit at right angles to the axis thereof; but any other suitable type conduit or suction tube, and any other type of extension or angular inclination may be employed.
Suction effect augrnenters may be used in connection with the suction tubes. The augmenters may comprise enlarged months at the outer end of the suction tubes.
In the text and claims, by tubes of the straight line wall type is meant this type at the aspiration point; by 'tube is also meant duct, channel, passage; by suction tube is meant any tube whichconveys suction fiow, also in part; by conduit or fiow tube is also meant channel, duet, passage, ducted burner, exhaust tube, exhaust nozzle; by *fiuid is meant any substance which is capable of flowing, as a liquid, a gas, or readily movable solids.
The principles involved in this invention may be applied to all fields of fluid fiow, as related to suction.
Changes in form and construction may be made without departing from the spirit or scope of the invention.
