Solenoid valve with magnetometric sensors

In a solenoid valve for switching the direction of flow of pressure fluid by driving the solenoid valve by pilot fluid pressure, ring-shaped magnets 13A and 13B are fitted at small-diameter regions 11a formed at end portions of a valve element 11 and fixed by end caps 14A and 14B which form contact...

Zusammenfassung:	In a solenoid valve for switching the direction of flow of pressure fluid by driving the solenoid valve by pilot fluid pressure, ring-shaped magnets 13A and 13B are fitted at small-diameter regions 11a formed at end portions of a valve element 11 and fixed by end caps 14A and 14B which form contact faces for pistons 14A and 14B. A housing chamber 30 is formed outside a valve hole 10a in a valve body 10 and in a position close to the magnets. Magnetometric sensors 31A and 31B are housed in the housing chamber 30, and a cover 35 is mounted to the housing chamber 30. The cover 35 has a connector 37 for a wire supplying pilot valves 20A and 20B and signal lines from the magnetometric sensors.
