    • A spool valve (22) controls a hydraulic drive, such as a drive for a fuel pump (18) in an internal combustion engine, in which the hydraulic drive comprises a driving piston (34) journalled in a hydraulic cylinder (33) which through a flow passage (31) is in communication with the spool valve. The spool (38) may occupy a position in which the flow passage is connected with a high-pressure source (29) and another position in which the flow passage is connected with a low-pressure port (30). The spool is settable by means of a positioning means (23) electrically activated by a control unit (16) which determines intended positions of the spool and for a movable part (56) in the positioning member. The movable part has windings (51) positioned in a magnetic field in a slit (60) which is oblong in the longitudinal direction of the spool. A sensor (66) signalizes the actual position of the movable part to the control unit (16). The movable part and the spool (38) are attached to each other so that the spool valve follows the movements of the movable part (56). The control unit (16) supplies current to the windings if the actual position of the movable part differs from the intended position.

    • An actuator for relatively moving two parts in a damped manner. The actuator includes a damper housing for connection to a first of the parts. The damper housing includes a damper chamber. The actuator includes a drivable damper rod for connection to a second of the parts and being movable relative to the damper housing. The damper rod includes a damper unit located within the damper chamber. The damper unit is relatively movable within the damper chamber with the damper unit movement corresponding to the relative movement between the damper housing and damper rod and the relative movement between the first and second parts. The damper unit is movable in response to hydraulic pressure force upon the damper unit. The actuator includes a pneumatic pressure source for providing a pneumatic pressure force that is transferred to provide the hydraulic pressure force upon the damper unit. The actuator includes a selectively actuatable blocking device for permitting transfer of the pneumatic pressure force from the pneumatic pressure source and blocking return of force to the pneumatic pressure source until the selectively actuatable blocking device is actuated.
    • 用于以阻尼方式相对移动两个部件的致动器。 致动器包括用于连接到第一部件的阻尼器壳体。 阻尼器壳体包括阻尼室。 致动器包括可驱动的阻尼杆,用于连接到第二部件并且可相对于阻尼器壳体移动。 阻尼杆包括位于阻尼室内的阻尼单元。 阻尼器单元在阻尼室内相对可移动,阻尼器单元运动对应于阻尼器壳体和阻尼器杆之间的相对运动以及第一和第二部件之间的相对运动。 阻尼器单元可响应于阻尼器单元上的液压力而移动。 致动器包括用于提供气动压力的气动压力源,所述气压力被传递以提供对阻尼器单元的液压力。 致动器包括可选择性致动的阻挡装置,用于允许气动压力力从气动压力源传递并阻止力返回到气动压力源,直到可选择性致动的阻塞装置被致动为止。
