The separate control valves (35) and their attached solenoid drives (4) are assembled on a support flange (16) in a plastic injection-moulded bottom part (2) and are joined by injecting plastic into the mould via injection holes (3). The whole valve assemb...

The proportional magnetic valve has an electromagnet with an armature that is movable in a housing (2) and with which a piston (6) can be moved in a bush (20) depending on a current. There is at least one component (34) that can be deformed in the axial di...

The choke valve (3) has at least one piston (5) that can be moved by a medium under pressure against a countering force and has at least one choke point. A pressure limiting valve (35) is associated with the choke valve as a pilot stage and contains a piez...

The pressure limiting valve has a valve body that is held in a closed position, in which the valve body closes a bore in which a medium is under pressure, via a rod (11) forming part of a drive. The drive is a piezo drive (12) with at least one piezoelemen...

The hydraulic system for actuating, in particular, steering and switching functions in a vehicle, has a tank for the hydraulic medium, from which the hydraulic medium is fed via a distributor valve to the two functional parts. The tank is connected to a co...
