ABSTRACT:
A piston compressor has a valve support, which closes a compression chamber and has an intake valve. A non-rotatable lamella can be moved between two positions, in one position the lamella lifts up from the valve support, leaving intake openings unblocked and in another position, the lamella closes the intake openings. A device is provided on the piston compressor for interrupting the supply. This device has a plate that is disposed between the lamella and the valve support and can be moved into two positions. The plate has openings, which continue the intake openings of the valve support. In the one position of the plate, its intake openings are covered by the lamella. In another position of the plate, intake openings thereof and the intake openings of the valve support are left unblocked by through openings in the lamella. The piston compressor can be used in compressed air brake systems of commercial vehicles.
