Abstract

1,147,238. Rotary positive-displacement compressors. WORTHINGTON CORP. Nov.22, 1966 [Dec.10, 1965], No.52242/66. Heading F1F. Air-compressing apparatus includes a rotary positive-displacement compressor 12 having a control valve 16 on the low-pressure side thereof, and a pump 26 that by-passes a non-return valve 22 on the high-pressure side of the compressor and expels compressed air from the latter into either an air-receiver 18 or the atmosphere whenever the valve 16 closes to effect unloading of the compressor. Preferably, the valve 16 is coupled by a rod 40 to a valve 38, which controls the rate of flow of lubricating oil through a pipe 32 into the compressor, so as to reduce said rate when the compressor is unloaded and thereby minimize the work done by the pump 26. Oil mixed with the compressed air is collected in the receiver 18 and flows through filtering means 34 and cooling means 36 before it reaches the valve 38. A separator 30 removes oil and water from the compressed air as it leaves the receiver through a pipe 28. When the valve 16 closes, the pump 26 may reduce the pressure in the associated pipe 24 and the outlet side of the compressor to a negative value relative to atmospheric pressure; and the pump may be driven continuously by the compressor or, alternatively, only while the valve 16 is closed, in which case the pump may be coupled to the compressor by a clutch (not shown). The rod 40 may be replaced by a rod (46), Fig. 2 (not shown), which is operated by a diaphragm or piston (48) is response to pressure changes effected by an actuator (43) for the valve 16.
