PCT No. PCT/SE81/00015 Sec. 371 Date Sep. 21, 1981 Sec. 102(e) Date Sep. 21, 1981 PCT Filed Jan. 23, 1981 PCT Pub. No. WO81/02185 PCT Pub. Date Aug. 6, 1981.An electrohydraulic set device includes, as an output element, a piston which is operable by a hydraulic pressure against the action of a return force. The hydraulic pressure is led to the working side of the piston via a valve passage. The valve passage is opened and closed by an electromagnet operated control slide. The control slide is arranged along a piston rod connected to the piston together with a coil of the electromagnet, the armature being arranged therebetween, in a common chamber, of which the working side of the piston forms part. A spring force between the control slide and the piston tends to move the slide against the action of the magnetic force in a direction closing the passage. The control slide lies to the side of the piston. |
