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

A valve block assembly for multiple valves, in particular expansion valves and/or shut-off valves, includes a valve block having a plurality of flow paths for fluids and a plurality of adjustment units with assigned drive units, wherein the valve block is designed as comprising two parts, these being a flow path element with the flow paths and a limiting element.

Valve block assembly for several valves

A ball valve (), particularly for use in motor vehicle refrigerant circuits, having an actuator (), a shaft () including a shaft bearing (), a ball () including a ball passage (), and a valve housing (). A fluid shaft seal () is arranged in the shaft bearing () between an upper shaft seal () and a lower shaft seal (), wherein the fluid shaft seal () is formed by a cavity () in which a sealing fluid is provided, and that the sealing fluid is in contact with the shaft () in a sealing region () such that the sealing fluid has a sealing effect in the axial direction, wherein the cavity () is at least partially formed by a diaphragm () and is limited on the shaft () by the shaft seals (), and that the diaphragm () is formed in such a way that pressure can be applied to the side facing away from the sealing fluid.
