摘要

3-way pilot solenoid normally open or normally closed indistinately for gaseous fluids and pressures comprised between 0.5 and 10 bars, characterized in that in its operation as normally closed the fluid enters through a drill and goes to a chamber formed between a servo piston and a clapet, not letting the solenoid valve escape air because the servo section is larger than the clapet that contacts a closing part, there is a push that keeps the valve closed, in this action a pressure spring, so that when excited an electric coil that involves, it attracts an internal part that closes the magnetic circuit, which involves through a ball joint mechanism a threaded screw that attracts the set formed by the servo, the clapet, and the rest of the pieces that form the slide, which when moving also moves the clapet that stops sitting on the closing piece to settle it is placed on the contiguous piece opposite, so that in this position the fluid inlet is put in communication with the corresponding outlet of use, remaining in this position while the coil acts which, when it stops acting, closes the device with which the pressurized fluid that has gone to the use is put in communication with the exhaust through the annular crown formed between the slide and the seat piece, discharging the fluid to the atmosphere.
