OIL FEEDER DEVICE Filed April 28, 1953 2 Sheets-Sheet 2 1N VEN TOR.
United States Patent O OIL FEEDER DEVICE Lomer Lee Richardson, Nutley, N. J. Application April 28, 1953, Serial No. 351,709 1 Claim. (Cl. 230-206) This invention relates to an oil feeder `device and more particularly to a portable oil feeder device.
The commonly used gas compressors employed in the manufacture of refrigerators and the like are constructed s as to have au .oil well container or splash pot wherein the crank shaft of the compressor is disposed. The operation of these compressors, which may be of the one piston cylinder or two piston cylinder type, effects lubrication of the piston by means of the splash eifect obtained by the rotation of the piston rod in the oil of the oil well. In the course of prolonged operation, the amount of oil in the oil well diminishes and needs to be replaced. The need for replacement of this oil is infrequent and may be at intervals of about three months more or less. The introduction `of small amounts of oil into the splash pot of conventional refrgerating machines has been a cumbersome procedure, which procedure has now been simplified by the use of applicants oil feeder device of this invention.
According to this invention applicant employs the compressive ability of the refrigerant compressor as well as the pressure of the compressed refrigerant to pump oil from a residual portable reservoir into the splash pot. This introduction of the o-il into the splash pot may be done without dismantling or stoppnig the operation of the compressor. Preferably, however, any back pressure disposed on the surface of the oil in the splash pot is released to the atmosphere so that the oil pumped into the splash pot by the use of applicants portable reservoir will be introduced into the splash pot against only the pressure of the atmosphere.
This invention will be more clearly understood by turning to the illustrative embodiment shown in the accompanying drawings in which Fig. l is a cross-section of a conventional single cylinder compressor showing, broken away in part, the portable reservoir of this invention,
Fig. 2 is a cross-section of a three-way valve, taken on line 2-2 of Fig. 5, two of which yare used in this invention,
Fig. 3 is a cross-section of one embodiment of a portable reservoir used to introduce oil into the splash pot of a compressor,
Fig. 4 is a side view of a different embodiment of this invention showing a structure capable of withstanding high pressure,
Fig. 5 is a top View of a three-way valve used in this invention, and
Fig. 6 is an end view of the three-way valve and showing a closure cap thereon.
Turning to the drawings and particularly Fig. 1, a splash pot 1 having a horizontal base is secured to a piston block 2 by means of bolts 3. A valve block 4 is secured to the top of the piston block 2 by conventional means such as screws (not shown). The valve block 4 is provided with an inlet port or opening and an outlet port or opening. A piston head block 5 having a suction linlet opening and a compressed gas exit opening is dis- 'i ing or other conventional means.
posed over the piston block in such ya manner that lthe suction opening of head block 5 is disposed over the inlet port of the valve block with `the opening of the head vblock 5 used for compressed gas being disposed .over the outlet port .of the valve block 4. Piston head block 5 is ,Secured to valve block 4 'by .conventional means such `as bolts (not shown).
A piston 6 of conventional design is disposed within the cylinder of the piston block .2. A piston .rod 7 is secured to the piston and to a crank shaft 8, the latter being substantially centrally disposed in .the splash pot 1. The piston rod 7 is provided at its base with a circular cam eccentric 9 `adapted to be rotated upon the surface of and into the b ody of the .oil .disposed in .the splash pot. A pair of three-way valves 10 are secured to the compressor, one of said pair being secured to the head block 5 and the other to a ,cylindrical tubular pillar 11 vcommunicating with the oil of splash pot 1. The `three-way valve connected .to the piston head block 5 -is secured to that section of the header having a bore hole therein adapted to transport the compressed gas from the outlet valve 12.
Turning to Figs. 2 and v5 the three-way outlet valve has a first bore hole 13 adapted to communicate with .the high pressure bore 14 disposed in head block 5. A second bore hole 1S communicates with said bore hole 13 at a right angle., said bore hole 15 being connected to outlet pipe 16. The bore hole 13 also communicates with a third bore hole 17 disposed i11 SPaced .relationship to the second bore hole 15. The third borehole 17 in turn communicates with a threaded' valve .exit opening 13. A valve stem 19 having `a valve block 20 thereon is disposed within the valve 10 in such a manner that it may be actuated to cut olf bore hole 13 from communication with bore holes 15 and 17 or it may be actuated so as to permit the high pressure in bore hole 13 to communicate with the outlet opening 18. A threaded pipe 21 is secured to exit opening 1S and ran angle cap 22 is in turn secured to said pipe 21.
A reservoir container 23, preferably *of cylindrical design, is provided with a bottom section 24 preferably welded to the cylindrical Section 23. A head plate 25 having a centrally disposed circular opening therein is secured to the top of cylindrical element 23 also by weld- The head plate 25 is provided with threaded bore holes therein adapted to receive threaded rods 26. The head plate is also provided with a circular upright ring section 27.
A detachable top plate 27x is secured to said plate l25 by means of wing nuts 28 disposed over threaded rods 26. The detachable top plate 27x is provided with an inlet orifice and an outlet orice. The inlet orifice is provided with a threaded inlet nipple 29. The outlet orifice is similarly provided with a threaded nipple Sil. The detachable top plate 27x is provided with a circular groove. The circular ring section 27 is disposed in the circular groove of the top plate 27x in compressive relationship against `a circular packing or stuffing 31. A well pipe 32 is screwed into the outlet opening of the detachable top plate 27 and is of such range as to be in close proximity to the bottom plate 24 of the portable reservoir. Clearly gas pressure introduced through inlet nipple 29 is disposed onto the surface of oil 33, working the oil up through pipe 23 and out of outlet nipple 30.
An inlet conduit 34 is disposed between angle cap 22 and inlet nipple 29. An outlet conduit 35 is disposed between outlet nipple 30 and the three-way valve secured to tubular element 11 of splash pot 1. The three-wa; valves 10 are provided with a pair of apertures 36 adapted to receive bolts for securing said valves to the compressor.
In the operation of applicants portable oil feeder,
, 3 conduits 34 and 35 Aare secured to the pair of three-way valves through their threaded openings 18, the conduit 34 being secured to the three-way valve disposed in coacting relationship with the high pressure of the outlet valve 12. The other three-Way Valve is secured to the tubular projection l1 of splash pot 1 so that the high pressure created by the piston 6 disposed in piston block 2 forces the outlet valve 12 to open against its spring 37, forcing the compressed refrigerant gas through bore khole 14 and into inlet conduit 34. The compressed gas is then communicated to the surface of oil 33 forcing the Aoil through conduit 35 into splash pot l. lt is thus apparent that the refrigerant gas from the refrigerator coils (not shown) is introduced through inlet bore hole 38 of the piston head block 5 and thence through inlet valve 39 into the vacuum chamber formed by piston 6 on the downward or suction stroke of said piston clock 6.
Obviously on the compression stroke of piston 6, the compressed refrigerant gas is forced dirough outlet 12, and when the valve block 20 allows open communication between bore hole 13 and threaded opening 18 the energy of theV compression stroke is used to transfer oil from the reservoir of cylinder 23 into the splash pot 1.
While this invention has been described by means of an embodiment thereof, it is not to be limited to this 25 embodiment since other embodiments will become apparent to those skilled in the art upon reading the above descriptive disclosure.
Having described my invention, what l claim and desire to secure by Letters Patent is as follows:
In. a compressor adapted to compress refrigerant gas, and having a cylinder block `and a piston and piston rod therein, a crank case and a crank therein connected to said piston rod, a valve block and a top plate, said top plate having a borehole for passage of compressed gas,
