PROPORTIONAL HYDROGEN SOLENOID VALVE

The invention relates to a proportional hydrogen solenoid valve, comprising a fixed core (2) and a mobile core (3) that can move axially relative to the fixed core, in which primary elastic return means (8) linked to the mobile core and secondary elastic means (9) linked to sealing means (16) are provided to allow fluid to flow through inlet and outlet ports (11, 12), in which the sealing means are located in a slider (10) that can be moved by the movement of the mobile core, in which the slider is made up of a cylindrical body defined by a first portion facing the mobile core and a second portion oriented towards the inlet and outlet ports for the circulating fluid, the first portion having a larger external diameter than the second portion, in which the slider has a termination at the free end of the second portion, said termination made up of a frustoconical section (101) from which a cylindrical extension (102) extends, intended to seal the outlet.
