<p>A device for controlling the operation of pumps in hydraulic circuits by detecting the pressure of the circuit and consequently activating or stopping the pump. The device comprises an oscillating circuit (23), in which the capacitor (17) is a capacitive transducer which cooperates with at least one mechanical actuator (10) for actuating at least one of the plates (15, 18) of the capacitor (17), and means for interfacing with the pump; the actuator (10) is subjected to the pressure of the fluid. <IMAGE></p> |
