Abstract:
A gas compressor comprising:a compressor case having an inner end wall portion at an inner sealed end thereof; a cylinder disposed in the compressor case; a pair of side blocks mounted on end surfaces of the cylinder; a compression chamber disposed in the cylinder for receiving a high pressure cooling medium gas containing a lubricant oil component; a first discharge chamber in communication with the compression chamber; a cylinder discharge port for discharging the high pressure cooling medium gas containing the lubricant oil component from the compression chamber to the first discharge chamber; a second discharge chamber disposed between the inner sealed end of the compressor case and a first one of the side blocks for receiving from the first discharge chamber the high pressure cooling medium gas and lubricant oil component; and an oil separator comprised of a discharge pipe for separating the lubricant oil component from the high pressure cooling medium gas, the discharge pipe having a first open end connected to the first side block in fluid communication with the first discharge chamber and a second open end through which the high pressure cooling medium gas containing the lubricant oil component exits into the second discharge chamber, the second open end of the discharge pipe opening in a direction towards and disposed proximate to the inner end wall portion of the compressor case so that the high pressure cooling medium gas containing the lubricant oil component collides with the inner wall portion of the compressor case immediately after exiting from the second open end of the discharge pipe to separate the lubricant oil component from the high pressure cooling medium gas.
