Control device for fluid actuator e.g. linear drive, has inlet valve, working valve and load control valve that are controlled by valve driver stage arrangement and provided for guiding exhaust air of actuator to air-pressure transducer

摘要

The device has an air-pressure transducer (24) provided with an electrical generator for generating electrical energy and an energy storage, where the device is arranged in a common housing. The transducer is connected with a pressure line (16) by a load control valve (23). A valve driver stage arrangement (29) is connected with the valve for opening the valve during undershooting of a given charge state of the energy storage. An inlet valve (17), working valve (18) and the control valve are controlled by the arrangement and guide an exhaust air of an actuator to the transducer.
