Oil Circulation System For A Compressor

Abstract

An oil circulation system for a compressor comprises a control valve body integrated therein with a pressure sensor, a differential pressure sensor and a temperature sensor. The control valve body is further integrated therein with a temperature control valve connected to an external cooler for lowering a temperature of a hydraulic oil, an oil filter for filtering the cooled hydraulic oil into a clean hydraulic oil, and a pressure relief valve for relieving a pressure of the clean hydraulic oil, which is then circulated back into the compressor for use. The integration of the aforementioned components effectively downsizes an entire set of machinery comprising the compressor and the oil circulation system and increases an efficiency of the compressor.

1 . An oil circulation system for a compressor, comprising:
 a control valve body integrated therein with a pressure sensor, a differential pressure sensor and a temperature sensor, wherein the control valve body is further integrated therein with a temperature control valve connected to an external cooler for lowering a temperature of a hydraulic oil, an oil filter for filtering the hydraulic oil into a clean hydraulic oil, and a pressure relief valve for relieving a pressure of the filtered hydraulic oil, which is then circulated back into the compressor for use.   
   
   
       2 . The oil circulation system as claimed in  claim 1 , wherein the control valve body is connected to external oil pipes by a plurality of square flanges.
