hydraulic vorsteuerbares 2-way einbauventil in sitzventilbauweise.

摘要

A hydraulically pilot-controlled two-way built-in valve (10) in seat-valve style for safety circuits is proposed in which an opening-pressure face (38) and a closing-pressure face (45) are arranged in the adjusting device (13) allocated to a valve cartridge (11) in such a way that a space (36) relieved to the tank is connected between their allocated pressure spaces (39, 44). Apart from a simple type of construction, greater functional reliability is achieved, since leakage oil cannot mutually affect these pressure spaces (39, 44). Furthermore, in a special design of the adjusting device (13), a dividing wall and one of the pressure spaces can be dispensed with. IMAGE
