Abstract:
A solenoid valve comprising a body in which there is fixed an electromagnet having a lockable plunger core carrying at least one valve member and slidable between first and second positions corresponding respectively to an excited state and to a rest state of the electromagnet, and a pushbutton mounted on the body to be manually operable,firstly, said pushbutton is slid along a direction that is transverse to the plunger core between an active position in which a cam-forming end of the pushbutton co-operates with the plunger core to bring it into its first position and an inactive position into which the pushbutton is returned resiliently and its cam-forming end is disengaged from the plunger core, and secondly, while in the active position, said pushbutton is at least partially rotated around said direction between a locked position in which the pushbutton lockingly co-operates with an abutment element secured to the body which opposes resilient return when said abutment element at least partially engages a portion of the pushbutton, and an unlocked position in which the pushbutton is unlockingly aligned with the abutment element along a portion thereof when the pushbutton is rotated from the locked position, wherein the abutment element includes means enabling it to be releasably fixed to the body.
