| 141 | Compressor unloading control | US3788776D | 1972-08-10 | US3788776A | 1974-01-29 | POST R; HERSCHLER M |
| An unloading control arrangement for a liquid injected air compressor of the type which includes a pneumatically operated inlet throttling valve, a liquid separator-reservoir tank, and compressed air storage means. A pressure responsive switch connected to the compressed air storage means is operative, at a predetermined pressure condition, to actuate a single power operated valve which vents the separator-reservoir tank and causes the inlet throttling valve to reduce inlet air flow to the compressor. A vent line connected to the power operated valve includes a flow restrictor of suitable size to provide for a low residual pressure in the reservoir tank to insure adequate liquid circulation during compressor unloaded operation.

| 142 | Liquid injection system for globoid-worm compressor | US3752606D | 1971-12-14 | US3752606A | 1973-08-14 | ZIMMERN B |
| The invention relates to a system for injecting a liquid to ensure cooling, lubrication and leak-tightness in a globoid-worm compressor. In known systems the liquid is injected substantially parallel to the axis of the worm on the low pressure side of the compressor and in the vicinity of the pinions which cooperate with the worm. According to the invention, the liquid injection system comprises ducts formed in the casing of the compressor and opening in the vicinity of the pinions in the zone where the width of the crests of the worm threads is a minimum. Preferably the duct is oriented transversely to the plane of the pinions.

| 143 | Screw compressor | US3734653D | 1971-08-23 | US3734653A | 1973-05-22 | EDSTROM S; SECKMAN J |
| A liquid injected screw compressor having an intermediate housing member which supports a detachable screw rotor housing portion, a thrust bearing housing, and a pressure fluid control actuator for a sliding capacity control valve. The intermediate housing member also includes a cavity for distributing lubricating and cooling oil to the compressor. The screw compressor includes a substantially cylindrical casing fabricated of steel plate which is bolted to the intermediate housing member and encloses the screw rotor housing portion to serve as a pressure vessel for compressor inlet gas and for gas vented by the capacity control valve. A separate casing portion is bolted to the intermediate housing member and encloses the thrust bearing housing and the pressure fluid control actuator. The compressor is adapted to be mounted on a base or frame by means of legs attached to the cylindrical casing.

| A REFRIGERATING SYSTEM PROVIDED WITH MULTI-STAGE THROTTLING AND WITH A POSITIVE DISPLACEMENT COMPRESSOR OF THE ROTARY TYPE, THE CASING OF THE COMPRESSOR BEING PROVIDED BETWEEN ITS LOW PRESSURE AND HIGH PRESSURE PORTS WITH ONE OR MORE ADMISSION PORTS FOR INTERMEDIATE PRESSURE GAS FROM LIQUID SEPARATORS LOCATED BETWEEN THROTTLING POINTS. THE GAS FORMED DURING THROTTLING IS SUPPLIED THROUGH THESE ADMISSION PORTS TO THE WORKING COMPARTMENT OF THE COMPRESSOR. THE OPENING AND CLOSING OF THE ADMISSION PORTS IS ACHIEVED BY THE ACTION OF THE COMPRESSOR WHICH HAS ITS ROTOR LOBES OPERATIVE AS VALVES FOR THE ADMISSION PORTS.
