A valve () is introduced for a heat pump system in a motor vehicle, with at least one inlet (), at least two outlets () and a valve element () which comprises at least one throughlet () and at least one expansion recess () that can be brought into fluidic connection with at least one outlet ().

3-2 way expansion valve

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.

Device for regulating a flow through and distributing a fluid in a fluid circuit

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.

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.
