摘要

In a piston-type compressor, especially for generating compressed air in motor vehicles, there is a suction plate (1) on the underside of a valve support, clamped between the cylinder and cylinder head, facing the compressor piston. The suction plate consists of an active (3) and an inactive section (5). The active section (3), preferably consisting of a tongue-shaped active plate fitted in the centre, operates in relation to suction apertures (19) in the valve support while the inactive section (5) of the suction plate has at least one delivery aperture (9) in active connection with at least one delivery aperture (11) in the valve support. The suction plate takes the form of a disc, thus virtually eliminating waste space. The suction plate can be fitted between the cylinder and the valve support without additional components; when used in an energy-saving system, the suction plate can be rotated to produce differing degrees of overlap between suction and delivery apertures.
