Abstract

A device for conserving power is provided in a piston compressor, in particular a piston-compressor for generating compressed air in a motor vehicle and having a piston delimiting a compression chamber for generating compressed air, which, originating from the ambient environment, arrives in the compression chamber for compression by way of at least one suction connection formed on a cylinder head cover and an intake valve array arranged on a valve plate. For the purpose of conserving power, a pressure-dependently acting idling device is provided for the intake valve array having a dedicated suction lamella, which can be rotated by an actuator between a working position overlapping at least one suction opening and an idling position unblocking, at least in part, the at least one suction opening. The actuator actuates the suction lamella in a coordinated manner such that in the idling position, the suction lamella unblocks the at least one suction opening in the valve plate, at least partially, while simultaneously blocking adjacent pressure valve cross-sections, at least partially, and locks the suction connection at the cylinder head cover by a slider in order to form an increased dead space in the area of the cylinder head.
