Description
Aug. 23, 1938.
J. B. cocANouR COMPRESSOR Filed July 15, 1956 Patented Aug. 23, 1938 UNITED STATES PATENT oFFlcE f ,2,127,5 5o John B. (locanourp s j Calif. I I Application Jul 13 1936; fial,N6'. 90,371 1 Claim. o1.2s+17'1) The present invention relates particularly to a compressor for use in mechanical refrigerators.
It is an object of the invention to provide a compressor of the character indicated so constructed and arranged as to obviate the necessity of providing intake and exhaust valves, and that will entirely eliminate oil scraping.
It is also an object of the invention to provide a compressor of the character indicated that will greatly simplify and expedite the operation of purging.
It is still another object to provide a compressor so constructed and operated that it may be used to evacuate the condenser and connections when repairs thereto are found necessary.
Finally, it is an object of the invention to provide a compressor of the character indicated that will be economical to manufacture, simple in form and construction, positive in operation, strong, durable, and highly efficient in its practical application.
In the drawing:
Figure 1 is a sectional view through a compressor embodying my invention.
Figure 2 is a sectional view substantially on line 2-2 of Figure 1.
Referring now more particularly to the drawing, I show at l and 2 two spaced and parallel circular plates encompassed by an annular member 3 which is bolted thereto, the parts [,2 and 3 forming a substantially closed chamber in' which the rotor hereinafter described is mounted.
The plate 2 has an inwardly projecting peripheral flange 4 and is provided with an inlet port 5 to which the suction line, shown .in part at I, is connected. This plate also has a duct 8 formed therein and extending from a point adjacent its center to and through flange 4 as shown, forming a passage whereby fluid may flow from the central portion of the chamber to the outer portion thereof.
Formed on the plate 2 and. eccentrically disposed relative to its axis is a spindle 9.
The rotor comprises an annular cylinder block In fitting snugly between plates l, and 2 and in the angle formed by flange 4 and plate 2, the outer surface of the block forming one wall of suction chamber l l, and compression chamber I2, the two chambers being separated by parts [3 and I4 extending inwardly from member 4.
At I5 is shown a portion of the drive shaft provided with a wide flange 16 seated in and secured to the rotor [0 as at ll, the shaft operating in a bearing 18 in plate I, leakage being prevented by means of any suitable seal as at I9.
Rotat-ab-ly mounted on the spindle 9 is a plate 20. Radially disposed cylinders as 21, 22, 23, 24 are formed in block H) to receive pistons 2 la, 22a, 23a, 24a. One piston, as 21a is pivotally mounted on a connecting rod 2Ib which is rigidly attached to the plate 20, while the other pistons are pivotallyconnected to the plate as indicated I at 22b, 23b, 24b.
The parts [3, I4 separating the two chambers H and [2 are disposed diametrically opposite each other, andare so disposed relative to the connections of the connecting rods to plate 20 and the position of the spindle 9 to the center of the rotor that when one piston is thrust outwardly to the fullest extent it is directly opposite part l3, the opposite piston being retracted to the fullest extent and opposite part Hi. When these two pistons are in the positions stated the other two pistons-are at points intermediate their strokes.
When in operation the movement of the'rotor is in the direction indicated by arrow 25, the pistons moving as a unit therewith. Since the connecting rod 2Ib is rigidly connected to plate 20 it follows that plate 20 is rotated about its eccentric mounting 9, the piston 2 la thereby being reciprocated through one complete cycle during each complete rotation of the rotor.
This movement of piston 2la is duplicated by each of the other pistons, thereby drawing fluid into chamber [I through duct 8 during one-half of a revolution of the rotor and discharging fluid into chamber l2 and thence out through port 26 during the other half of the revolution of the rotor.
In this manner fluid is pumped from suction line 1 to discharge 26. without passing through any valves, and all of the difficulties attendant pump mechanically simple because few and simple parts are required and little machine work is required. The simplicity of the device is partly due to the form of plate 2 which cooperates with its flange 4 to form a bearing for the rotor.
Another feature of the invention is the location of the ports 5 and 8, these being placed on opposite sides of the part 9. In a mechanical re- A compressor comprising, in combination, an annular disc rotor defining in part a central chamber and having radial cylinders formed therethrough, pistons operative in thecylinders and actuating means therefor, a shaft having a terminal flange thereon concentrically seated in said rotor to form one side of said central chamber, a housing supporting the shaft and encompassing the rotor to complete the central chamber and having one portion of its peripheral wall spaced from the rotor to form an annular chamber therebetween and another portion forming a bearing support for the rotor, means associated with the housing to divide the annular chamber into a suction and a discharge chamber, a duct leading from the central chamber through the housing wall opposing the terminal flange to the suction chamber, a discharge port leading through the housing to the discharge .phamber, and an inlet port leading directly through the side wall of the housing opposite the terminal flange to the central chamber.
