Title: SUBASSEMBLY FOR A COMPRESSOR, IN PARTICULAR IN A MOTOR CAR
Abstract:
The present invention relates to a subassembly (200) for a compressor and comprises a first electrical control valve (102) which has a valve housing (108) which is provided with connections for the high-pressure region (Pd) and for the crank chamber pressure region (Pc) and which has a valve member (110) which is arranged within the valve housing (108) and which can be displaced between two positions. The valve member (110) connects or separates the two regions. A second electrical control valve (116) has a valve housing which is provided with connections for the crank chamber pressure region (Pc) and for the suction pressure region (Ps) and which has a valve member which is arranged within the valve housing and which can be displaced between two positions, wherein the valve member either connects the two regions to each other or separates them from each other depending on the position. An electrical control device controls, during operation of the refrigerating medium compressor, a fluid flow between the high-pressure region (Pd) and a crank chamber pressure region (Pc) by means of the position of the valve member of the first control valve (102), and controls the fluid flow between the crank chamber pressure region (Pc) and a suction pressure region (Ps) by means of the position of the valve member of the second control valve (116) in accordance with the control of the first control valve (102).
