Abstract (en)
[origin: EP0845602A2] The device functions independently of electrical input signals to proportional magnets and has valve devices operating with 4-2 function. The valve devices for control of the volume flow coming from the positioning motor have a releasable seat valve and a slide valve for control of the backward-flowing volume flow. The control members of the seat and slide valves are arranged behind one another in a longitudinal bore of a housing, so that the slide valve is located between the seat valve and the proportional magnet. The seat valve (11) and the slide valve (12) have separated control members (22,45) which are in mechanical work connection with one another. A first adjustable device, by altering the tension of a regulating spring, adjusts one of the volume flow. A second adjustment device (53) is also provided, with which the other volume flow is adjustable.
