Control arrangement for piston of position motor - involves formation of control edges on control slide

摘要

Control arrangement for the working piston of a pressure medium actuated position motor in which the working piston (1) is connected to a control slide (10) which is movable relative to a control element (12) and subject to a control pressure (Ps) against the force of a spring (14). Control edges (17,18) to block and release the pipes (19,26) for the inlet and outlet of the pressure medium are formed on the control slide. USE/ADVANTAGE - Position motor in which preset intermediate positions of the working piston can be reliably engaged.
