Abstract
A reciprocating piston compressor which is driven by a rotating camshaft and cam. An auxiliary piston is located below the compression piston. The auxiliary piston is movable by a regulated control pressure against the compression piston so that the compression piston is stopped at its top dead center position. Thus, the reciprocating piston compressor is disabled since the compression piston is no longer driven by the rotating camshaft and cam.
Claims9
An arrangement for disabling the movement of a reciprocating piston of a pneumatic compressor comprising, a cylinder housing having a compression chamber, a compression piston disposed in said compression chamber and having an operating tappet, a rotating cam engaging said operating tappet for driving said compression piston through a compression stroke, a restoring spring biasing said operating tappet against said rotating cam for driving said compression piston through a suction stroke, and an auxiliary piston concentrically disposed about said operating tappet and cooperatively associated with said compression piston and acted upon by a control pressure to disable said compression piston by holding said compression piston in its top dead center position.
