摘要：
A compressor unloaded system for use in compressed air supply systems having reciprocating type air compressor means supplied with atmospheric or turbocharged air is shown. Means are provided to block off the air intake of such compressors, and to maintain back pressure against the exhaust valve of said air compressor during an unloading cycle, thereby preventing operation of the intake and exhaust valves of such compressor, and creating an "air spring" in the cylinder of such air compressor during an unloading cycle.
