The invention relates to a solenoid valve having a coil, a magnet core, an armature, a yoke tube, a pole piece and a valve housing. The sealing and connection between the pole piece and the coil and/or the pole piece and the valve housing is effected by means of respective clamp-cutting edge connections each having a nose-like projection.

Solenoid valve

A solenoid valve achieves high reliability and small size with fine tolerance. The solenoid valve having a valve housing, an electromagnet composed of a coil, a yoke and a clapper armature having at least a first valve seat, and a sealing element which can be actuated by the clapper armature and which co-operates with the first valve seat. The yoke has yoke pins and the clapper armature is magnetically and pivotally connecting with one of the yoke pins at the end thereof that is remote from the sealing element. The clapper armature is guided through the coil.

The pressure-reducing valve according to the invention makes available at its secondary pressure connection a generally adjustable secondary or working pressure which can be used by connected compressed-air consumers. The pressure-reducing valve provides a constant working pressure irrespective of fluctuations in the primary pressure or in the consumption of compressed air by the compressed air consumers. In the pressure-reducing valve according to the invention, a second pressure chamber in the central region of the slide is exposed to the primary pressure via a primary pressure connection. First and third pressure chambers at the end regions of the slide are, on the other hand, exposed to the secondary pressure via a secondary pressure connection. In addition, third and fourth chambers are connected to one another by way of a third connecting duct.

Pressure-reducing valve

The invention relates to a valve having a housing in which there is a passage having at least two spaced ports. A slide is accommodated in the passage for to and fro movements between at least two positions in one of which at least one of the ports is open and in the other of which such port is closed. A slide actuator effects movements of the slide and the slide carries a seal which effects a seal of the closed port when the slide is in the port-closing position. The seal has a sealing actuator operable separately from the slide actuator to apply a sealing force to the seal. The force applied to the seal is neutralized in response to actuation of the slide.

Valve construction

The invention relates to a valve with a housing, a valve seat and a setting member which is provided in the housing and has a seal, the sealing surface of which comes into contact with the valve seat in the closed position of the setting member, and wherein during the adjustment the valve seat is retained on the housing so as to be displaceable relative to the sealing surface. During the adjustment the valve seat is also movable in an angular range in such a way that the valve seat rests flat on the sealing surface in the closed position.

Valve

The invention relates to an electromagnetic valve having a passage therethrough and a closure member which is reciprocable between first and second positions in whoch the passage is openend and closed. An electromagnectic controllable actuator effects movement of the closure member against a spring force from the first position into the second position. The valve includes a retainer which retains the closure member in the second position. The retainer is formed by a piezoelectric bending element which locks the closure member positively in the second position.
