COMPRESSOR Filed April 1, 1957 INVENTOR. BER TRAM J. ROCH LU 5 ATTORNEYS United States Patent COMPRESSOR Bertram J. Rochlus, Milwaukee, Wis. Application April 1, 1957, Serial No. 649,671
1 Claim. (Cl. 230- 147) This invention appertains to compressors or pumps and more particularly to a novel device embodying a compressor plate operating in a chamber with the plate and chamber so constructed and porportioned that during movement of the plate fluid will be drawn in at one side of the chamber and forced out of the other side of the chamber under a desired pressure.
One of the primary objects of this invention is to provide a novel means for supporting the compressor plate on crank pins carried by crank discs with novel means for positively driving the discs in the same direction whereby the movement of the compressor plate in the chamber will be planetary for bringing about desired compression of fluidtherein and the delivery of such fluid under pressure to an outlet port.
Another salient object of this invention is to provide a novel sliding gate valve or vane normally urged into contact with the compression plate for effectively dividing the chamber into intake and exhaust sections.
A further important object of my invention is to provide a compressor of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a small cost.
With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawing, in which drawing,
Figure 1 is a longitudinal sectional view through the improved compressor taken on the line 11 of Figure 3, looking in the direction of the arrows;
Figure 2 is a view similar to Figure 1, but taken on the line 22 of Figure 3, looking in the direction of the arrows and illustrating the driving connection between the crank discs, and
Figure 3 is a transverse sectional View through the compressor taken on the line 3-3 of Figure 1, looking in the direction of the arrows.
Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter C generally indicates my improved compressor and the same includes a housing 5 having an interior compression chamber 6. The housing 5 can be fabricated in any desired way; however, the same embodies substantially semi-circular end walls 7 and 8 a substantially fiat connecting upper wall 9 and side walls 7 and 8'. The lower part of the chamber is divided centrally by a partition wall 10 having formed therein a guideway 11. Slidably mounted within the guideway 11 is a sliding gate valve or vane 12 for a purpose which will later appear.
Rotatably mounted within the housing 5 on opposite Patented Aug. 4, 1959 sides of the partition wall 10 are crank discs 13 and 14. These discs 13 and 14 are driven in the same direction in any preferred manner, and as illustrated the discs are provided with spur gears 15 and these gears have meshing therewith a drive pinion 16. The gears 15 and thecrank discs 13 and 14 can be provided at their axes with stub shafts 17 rotatably mounted in suitable bearings carried by the housing. The drive pinion 16 is mounted at its axis on a shaft 18 rotatably mounted in the housing and this shaft can constitute a power input shaft.
The crank discs 13 and 14 carry crank pins 19 and 20. Mounted within the chamber 6 for movement toward and away from the flat wall 9 is a compressor plate 21. The compressor plate 21 is of a one-piece construction and includes round piston terminals 22 and a connecting flat bridge portion 22'. ,The piston terminals 22 are rotatably mounted on the crank pins 19 and 20 and the outer faces of the piston terminals have rubbing contact with the walls 7 and 8. The housing on opposite sides of the partition 10 has formed therein an outlet port 23 and an inlet port 24, and the sliding gate valve or vane 12 separates these ports one from the other and is urged at all times into intimate contact with the lower face of the compressor plate 21. An expansion coil spring 25 can be provided for this purpose. In lieu of the coil spring 25 a bleed passageway can connect the outlet port 23 and the guideway 11 so that a constant pressure will be maintained in the guideway to urge the gate valve orvane 12 in its uppermost position.
In operation of my improved compressor and referring more particularly to Figure 1, it can be seen that upon rotation of the crank discs 13 and 14 and the crank pins 19 and 20 in a counterclockwise direction, that the compressor plate will be moved back and forth from left to right and up and down in the compression chamber 6. In the position shown in Figure l, the compressor plate has just passed its compression stroke and air is being admitted to the right hand side of the chamber through passageway 24 and fluid is being forced out of the left hand side of the chamber through passageway 23. As the plate 21 moves down and toward the left, see the dotted line position in Figure 1, the intake passageway 24 is cut off and fluid will now be compressed within the chamber upon the upward movement of the compressor plate and the fluid will be forced past the compressor plate on the left hand side toward the outlet passage 23.
Various changes in details may be made without de parting from the spirit or the scope of this invention, but what I claim as new is:
A compressor or the like comprising a housing having an interior chamber provided with substantially semi-circular end walls, a top flat connecting wall and side walls, said chamber being divided at its lower portion by a transversely extending partition wall, said chamber at its lower portion and opposite to the top flat wall having an inlet at one side of the partition wall and an outlet on the other side of the partition wall, crank discs rotatably mounted in the chamber adjacent to the opposite ends of the chamber having crank pins, means driving said crank discs in the same direction, a one-piece compressor plate including round piston terminals and a connecting flat bridge portion, said round piston terminals being rotatably mounted on said crank pins with the entire plate moving in the chamber in a planetary direction toward and away from the top fiat References Cited in the file of this patent wall and toward and away from the inletand outlet UNITED STATES PATENTS ports, the outer faces of said piston terminals having rubbing contact with the semicircular end walls, a ver- 21632 Tninmer Sept 1858 tically moving sliding gate valve carried by the parti- 5 1 31 g g g g tion wall and disposed between said ports, and dividing c H et a said ports one from the other, and means normally Johnson June 1941 urging the gate valve into sliding intimate contact with I the lower face of the compressor plate between th FOREIGN PATENTS piston terminals. 10 9,143 Switzerland Sept. 26, 1894
