摘要： A three-way or multi-way valve (1) is provided, which is built up of a plurality of two-way valves (11-14), each of which has a high pressure connection and a low pressure connection which are separated from each other by means of a valve seat with which a closure element co-operates, the two-way valves (11-14) being arranged to be operated in pairs or in groups by means of a control pressure fluid by way of a control pressure line (40a, 40b) opening into a pressure chamber (35a, 35b, 36a, 36b), and one of the two-way valves (pump valve 11, 12) of each group being arranged in a connection between a pressure source (6) and a load (2), and another two-way valve (tank valve 13, 14) of the same groups being arranged in a connection between the load (2) and a pressure sink (7). With a valve of this type, it is desired to obtain improved closing behaviour with simple construction. For this purpose, at least one of the connections, especially the high pressure connection, of at least one valve (11, 14; 12, 13) of each group communicates with the control pressure line (40a, 40b) by way of a throttle channel (33a, 33b, 34a, 34b).

A valve of this type should also be able to be operated reliably when water is used as hydraulic fluid. For this purpose, there is arranged in the control pressure line (40a, 40b) at the tank valve (13, 14) a non-return valve (37a, 37b) which closes towards the tank valve.

摘要： A two-way seat-type valve is provided, having a valve seat (24, 25) which is arranged between a first and a second connection, and having a closure element (20, 21) which co-operates with the valve seat (24, 25), is arranged in a guide (18, 19) so as to be movable towards the valve seat or away from the valve seat, and is subjected to a control pressure prevailing in a pressure chamber (35, 36) on the side, remote from the valve seat, of the closure element. A valve of this type should also be able to exhibit good reaction characteristics with water as hydraulic fluid. For this purpose, the closure element (20, 21) is guided seallessly in the guide (18, 19).

摘要： A control valve (1) is disclosed, having a housing (2) which has an input port (3) and an output port (4) that are connected to one another by a flow path in which a throttling device is arranged. It is desirable for such a control valve to be able to hold a volume flow constant, irrespective of the load pressure at the output port (4). For that purpose, the throttling device comprises a series connection of a first throttle (27), the passage of which is externally adjustable, and a second throttle (28), the passage of which is adjustable in dependence on pressure.
