Abstract
A solenoid valve comprising a body in which there is fixed an electromagnet having a plunger core carrying at least one valve member and movable between first and second positions corresponding respectively to an excited state and to a rest state of the electromagnet, and a manual control pushbutton mounted on the body transversely to the plunger core firstly to slide 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, to pivot between a locked position in which the pushbutton co-operates with an abutment element secured to the body which opposes resilient return, and an unlocked position in which the pushbutton escapes from the abutment element, the abutment element including means enabling it to be releasably fixed to the body.
