  • Patent number: 11767922
    Abstract: A multi-way valve for controlling a refrigerant circuit of a refrigeration system with a heat pump function, having a housing which has two mutually opposite end faces which each comprise an insertion opening to which a regulating chamber is connected, having multi-way valve arrangements which can each be inserted in the regulating chamber, the multi-way valve arrangement comprising at least one base body and a rotary slide valve arrangement, with in each case one connection in the housing, which open into the respective regulating chamber, and with at least further connections in the housing, which open into at least one channel which extends between the regulating chambers.

  • Patent number: 10619899
    Abstract: A multiway valve for controlling a refrigerant circuit (12) of an air conditioning system with heat pump function has a housing (14), first inlet opening (21) connected by a first fluid channel (22) to a regulating chamber (19), a second connection opening (22) connected by a second fluid channel (26) to the regulating chamber (19), another connection opening (29, 33) connected by another fluid channel (30, 34) to the regulating chamber (19), an actuator (37) that actuates a transmission element (39) by a drive motor (38), which extends in the housing (14) between the drive motor (38) and the regulating chamber (19), and a rotary valve assembly (55) in the regulating chamber (19) and coupled to the transmission element (39) to be driven by a rotary motion, into consecutive and divergent switching or control positions between the inlet opening (21) and the connection openings (25, 29, 33).
