A multiway valve for controlling a refrigerant circuit () of an air conditioning system with heat pump function has a housing (), first inlet opening () connected by a first fluid channel () to a regulating chamber (), a second connection opening () connected by a second fluid channel () to the regulating chamber (), another connection opening () connected by another fluid channel () to the regulating chamber (), an actuator () that actuates a transmission element () by a drive motor (), which extends in the housing () between the drive motor () and the regulating chamber (), and a rotary valve assembly () in the regulating chamber () and coupled to the transmission element () to be driven by a rotary motion, into consecutive and divergent switching or control positions between the inlet opening () and the connection openings ().

Multiway valve for controlling a refrigerant circuit

Switching valve for controlling a mass flow in a cold or hot circuit. The valve includes a valve housing having a feed opening and a discharge opening; a valve piston which has a valve-closure member directed towards the discharge opening and which, in a closed position, abuts a valve seat of a through-bore between the feed opening and the discharge opening; a pilot valve having a pilot bore in the valve piston, which bore opens into the through-bore and traverses the valve piston; a path-generating device having an actuatable ram accommodating a closure member which closes the pilot bore and, with the closure member, can be moved into an opening position which opens the pilot bore; and a bypass duct formed between the feed opening and the pilot bore. At least one connection element forcibly transfers at least some of the stroke movement of the ram onto the valve piston.
