<p>PURPOSE:To ensure a reflux feed quantity without excess and shortage of a recovered separated oil according to the operating state of a reciprocating type compressor. CONSTITUTION:An oil separating chamber 32 provided in a high pressure area in a machine, a primary oil basin chamber 41 for separated oil recovery continuously provided below the oil separating chamber 32, a main oil basin chamber 42 provided with a space on the side of the primary oil basin chamber 41 and connected to the primary oil basin chamber 41 through a through hole 43 having a head, a reflux oil hole 45 opened to a valve seat surface 44 formed on the bottom part of the main oil basin chamber 42 and allowing the main oil basin chamber 42 to communicate with a low pressure area 8 in the machine, and a valve means 50 for controlling the flow rate of the reflux oil hole 45 according to the differential pressure between high and low pressure areas. Thus, the reflux feed of a recovered separated oil suitable to the operation state of a compressor can be automatically accomplished.</p> |
