Abstract
The invention relates to a coolant compressor comprising an electric drive unit, a cylinder housing (1), a crankshaft (3) which can be driven by the electric drive unit, and a piston (2) that can be driven by the crankshaft (3) and is guided in a working volume of the cylinder housing (1) for cyclically compressing a coolant which can be conveyed via a suction valve into the working volume, said suction valve comprising a suction opening (7) and a valve closure element (8), preferably a valve spring, which closes the suction opening (7) in cycles. The aim of the invention is to ensure a continuous opening movement of the suction valve during the suction cycle. According to the invention, this is achieved by providing an actuation device (14; 15, 23) which is designed to open the valve closure element (8) in cycles.
