MECHANICAL CONTROL POWER TRANSMISSION DEVICE

摘要

A mechanical control power transmission device including a driver stage (25) consisting of a low-capacity hydraulic linear slide valve (1) with two outlets connected via ducts (41, 42) to two chambers (39, 40) at the ends of a high-capacity valve (24a) which is in turn connected to a means to be controlled. The position of the valve (24a) is controlled by means of a sensor (30) for sensing the position of the valve slide (26). Said device may be used in industrial plants.
