Abstract
An electric motor driven portable air compressor consists of a reciprocating piston and cylinder arrangement with an intake throttling valve operative to unload the compressor above a predetermined pressure level. The throttling valve is a spring loaded plunger responsive to compressor output to close one of two inlet openings to reduce the charge of air in the cylinder. A stainless steel intake leaf spring is disposed between the cylinder and a two part die cast housing and is responsive to cylinder suction for control of the compressor.
