BALL VALVE WITH INTERNAL SEAL ARRANGEMENT, IN PARTICULAR FOR USE IN MOTOR VEHICLE REFRIGERANT CIRCUITS

摘要

The invention relates to a ball valve (1) having an internal seal arrangement, particularly for use in motor vehicle refrigerant circuits, having an actuator (2), a shaft (3) with shaft bearing (5), a ball (4) with a ball passage channel (16) as well as a valve housing (13) with refrigerant connections (15), characterised in that the ball (4) has a floating bearing in the valve housing (13) and that the ball (4) is arranged between two ball sealing seats (9) for this purpose, wherein one ball sealing seat (9) is positively supported by the valve housing (13) and towards which a sealed bearing is provided by a sealing seat ring (10) and that a second ball sealing seat (9) is positively supported by a closure part (17) on the opposite side of the valve housing (13) and towards which a sealed bearing is provided by a sealing seat seal (10), wherein the closure part (17) has a sealed bearing towards the valve housing (13) by means of a closure part seal (22).

主权项

1. A ball valve (1) with internal sealing arrangement, in particular for being used in motor vehicle refrigerant circuits, comprising an actuator (2), a shaft (3) with shaft bearing (5), a ball (4) with a ball passage conduit (16) and a valve housing (13) with refrigerant connections (15), characterized in that the ball (4) is supported in the valve housing (13) in a floating mariner and that the ball (4) is arranged to this end between two ball seal seats (9), wherein a ball seal seat (9) is positively received by the valve housing (13) and is supported in a sealing manner against the latter by a sealing seat seal (10), and that a second ball seal seat (9) is positively received by a closure part (17) in the opposing valve housing (13) and is supported in a sealing manner against the latter by a sealing seat seal (10), wherein the closure part (17) is supported in a sealing manner against the valve housing (13) by a closure part seal (22).
