  • Patent number: 11884129
    Abstract: A device for regulating a throughflow and distributing a fluid in a fluid circuit, in particular a refrigerant. The device has a housing with ports for connecting to fluid lines which are connected to at least one inner volume of the housing designed as a valve chamber via a respective through opening, and at least one valve element arranged in the valve chamber with a drive element for moving the valve element relative to the housing. The at least one valve element is mounted such that it can be displaced in a linear manner in the axial direction along a longitudinal axis such that a passage for the fluid is opened between a first port designed as an inlet and a second port designed as a first outlet and/or a third port designed as a second outlet.

  • Patent number: 11724561
    Abstract: Device for controlling a flow-through and distributing a fluid in at least one fluid circuit, in particular a refrigerant in a refrigerant circuit including a housing with ports for connecting with fluid lines, each of which is connected via a passage opening with the at least one interior volume of the housing, as well as with at least one valve element disposed in the interior volume of the housing with a drive element for moving the valve element relative to the housing. The at least one valve element is supported rotatably about a rotational axis and comprises at least three through openings developed as through-bores forming in the interior of the valve element a common volume. An axis of symmetry of a first opening and the rotational axis of the valve element are located on a common axis. The device is used in a refrigerant circuit of a thermal system.

  • Publication number: 20220412470
    Abstract: A device for controlling a flow and distributing a fluid, in particular a refrigerant, in a fluid circuit. The device exhibits a housing with connections for connection to fluid lines that are connected to one internal volume of the housing via a pass-through opening, and one valve element that is arranged in the internal volume of the housing and exhibits a drive element for moving the valve element relative to the housing. The valve element exhibits one pass-through opening and is mounted in such a way that it can be moved linearly in the axial direction along a longitudinal axis such that a passage for the fluid is opened between a first connection produced as an inlet and a second connection produced as a primary outlet or a third connection produced as a secondary outlet.

  • Patent number: 11221076
    Abstract: Device for regulating and controlling a flow-through and distributing a fluid in a fluid circuit has a housing with ports connecting fluid lines that are connected across a passage aperture with an interior volume of the housing, a valve element disposed in the interior volume of the housing, a drive element for moving the valve element relative to the housing.

  • Patent number: 10962265
    Abstract: An expansion and isolation valve, specifically an electric expansion and isolation valve for operation with the coolant R744, featuring a valve body arranged in a valve body chamber, a seal seat, and a seal, which are arranged along an axial movement direction of the valve body in the expansion valve. The expansion valve is further designed such that in a closed state of the expansion valve, there is a pressure bypass to the valve body chamber, and preferentially, that a valve body diameter at the positions of the seal seat and the seal corresponds with the respective seal diameters.
