摘要： Disclosed is a solenoid-operated valve which hardly brings a plunger into a lock and is capable of improving its responsively. In the solenoid-operated valve, the plunger (16) slidably guided in an inner bore (11a) formed in a yoke (12) and a core (13) aligned axially is moved by energizing an electromagnetic coil (17), and a spool (26) in a valve section is moved through a rod portion (26a) which protrudes from an end of the plunger (16) to pass through a center hole of the core. An electromagnetic section fluid chamber (B) defined by a forward end surface of the plunger and the inner bore (13a) of the core communicates with an intermediate fluid (D) chamber defined between the core (13) and a valve sleeve (21), through a clearance (C) between the center (13a) hole and rod portion (26a). The spool (26) is provided at one end thereof with a land (27a) portion whose end surface defines a part of the intermediate (D) fluid chamber. The diameter (d1) of the land portion is chosen to be the same as the diameter (d2) of the plunger, so that the sum in volume of the electromagnetic section (B) fluid chamber and the intermediate (B) fluid chamber can be kept invariable regardless of movement of the plunger (16). A supply/drain (18) passage is further provided to permit the oil around the solenoid-operated valve to be charged into the rear (A) end fluid chamber or discharged therefrom upon movement of the plunger (16).

摘要： The invention relates to a directional-control valve (1) comprising a connection (A) on the front face thereof and at least one radial connection (B). The front faces of the valve body (16) (valve sleeve or seat body) of the directional-control valve are impinged by approximately the same pressure, so that the actuating forces for displacing the valve body are minimal. According to the invention, the pressure to be subjected on a rearward front face (18) of the valve body is tapped at an axial distance from the valve body.

摘要： An hydraulic valve has two outlets 43 and 44 and is switchable so that fluid can only be supplied to one outlet at a time. A spool 47 with two seals 48 and 49 is slidable in a housing 45 under the action of two solenoids 61 and 62 and is urged to a central position by two springs 56 and 57 where the seals block passage to both outlets 43 and 44. When the spool 47 is moved in one direction it allows flow to one outlet and also allows flow via a bypass channel 67, 69 to an opposite side of the spool counteracting the force applied by the solenoid so that the force applied to an outlet can be controlled gradually.

摘要： The shut-off vaive (1, 40, 85) comprises a valve housing (2) having at least two chambers (3, 4, 5) adjoining one another in axial direction. The chambers are communicating with one another through a passage bounded by a valve seat (6,7). A valve body (15) is axially movable in the housing and co-operates with each valve seat for closing the associated passage. The valve body is guided with sealed passages through the walls of the axially outer chambers opposite the valve seat (6, 7). The passages and each valve seat have substantially the same diameters. The valve body can be composed of an upper body and a lower valve body part both being provided with a sealing ring co-operating with the same cylindrical valve seat.
