ABSTRACT:
A device for remote control of hydraulic or pneumatic machine tools, comprising a selector valve for different hydraulic functions provided with a number of spring-centered slides and two electrohydraulic or -pneumatic converters connected to each slide, and comprising a control unit capable by electric impulses to transfer orders via a cable to a receiver unit capable to control the converters.
According to the invention, the control unit comprises a ring counter (B), which is controlled by an oscillator (A) and capable to emit in turn a scanning signal to each of a number of transducers (C1-C6), which are manually actuated by levers (1-6), each transducer being capable during the duration of the scanning signal to convert the direction and deflection from a centered zero position of the associated lever (1-6) into two signals, one (y) of which corresponds to said direction and one (z) to said deflection. An encoder (E) is provided to allot an address to the output signals. The receiver unit comprises a decoder (K) capable to emit a decoded signal to a signal converting circuit (L) thereby addressed where two such circuits (L) are corresponded by a transducer (C1-C6). The circuits (L) are connected each to an amplifier (M), each of which is capable to control one of said converters (N).
