Abstract (en)
[origin: EP0405187A1] In order to adjust the stroke of a control element (15) which is actuated electromagnetically by a spring-mass oscillation system (5,13,50), for displacement machines and in order to permit a free arrangement of the electromagnetic positioning device in the housing (8), in particular in a cylinder head of a displacement machine, the movement of the positioning device is transmitted to the control element, in particular one or more stroke valves or flat slide valves by means of a mechanical or hydraulic transmission system (10) with a variable transmission ratio. In addition, devices (54,55) are described for exactly setting the position of equilibrium of the oscillating system. The electromagnetic positioning device can also be combined with a limit position damper (7) or with a hydraulic compensation element (51) of known design. <IMAGE>
