Abstract: A ball valve with internal sealing arrangement for use in motor vehicle refrigerant circuits The ball valve includes an actuator, a shaft with shaft bearing, a ball with a ball passage conduit, and a valve housing with refrigerant connections. The ball is supported in the valve housing in a floating manner and is arranged between two ball seal seats. A first ball seal seat is received by the valve housing and is supported in a sealing manner against the valve housing by a first sealing seat seal. A second ball seal seat is received by a closure part in the opposing valve housing and is supported in a sealing manner against the valve housing by a second sealing seat seal. A first expansion notch and a second expansion notch extend from the ball passage conduit toward a chamber formed in the valve housing.

Abstract: 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.

Abstract: A ball valve (1), particularly for use in motor vehicle refrigerant circuits, having an actuator (2), a shaft (3) including a shaft bearing (5), a ball (4) including a ball passage (16), and a valve housing (13). A fluid shaft seal (8) is arranged in the shaft bearing (5) between an upper shaft seal (6) and a lower shaft seal (7), wherein the fluid shaft seal (8) is formed by a cavity (18) in which a sealing fluid is provided, and that the sealing fluid is in contact with the shaft (3) in a sealing region (19) such that the sealing fluid has a sealing effect in the axial direction, wherein the cavity (18) is at least partially formed by a diaphragm (11) and is limited on the shaft (3) by the shaft seals (6, 7), and that the diaphragm (11) is formed in such a way that pressure can be applied to the side facing away from the sealing fluid.
