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 valves, 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.

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.
