ELETTROVALVOLA DI PILOTAGGIO, IN PARTICOLARE PER CIRCUITO IDRAULICO.

摘要

The electric valve 1 comprises an electromechanical actuator 2 which generates a mechanical load for the spool of a proportional valve 3 inserted in a hydraulic circuit. The actuator 2, of the solenoid type, comprises a core 13 which can move by virtue of the magnetic field generated by an electric winding 17 surrounding it. The core 13 is integrated with a shaft 18 which passes through an end closure body 6 for the housing 4 of the actuator and extends through a body 34 accommodating the valve to form the spool of the valve itself. The shaft 18 is supported by supporting and centring portions 21 arranged in the closure body of the actuator.
