An improved electrically operated pilot-type, "instant-on" solenoid assembly for near-instantaneous control over the flow of compressed gas. The assembly may be applied in fuel systems for propulsion in vehicles using gaseous fuel. It includes a housing with inlet and outlet passages connected to a primary chamber where a primary piston is slidably mounted, a secondary chamber having a secondary piston slidably mounted within the chamber, a solenoid to produce translational movement of the pilot piston, and passageways linking the various components. When the solenoid is energized, the pilot piston is moved to permit fluid to flow from the primary to the pilot chamber, producing an increase in the differential pressure in the regions of the primary chamber. The differential pressure then forces the primary piston to move, exposing the outlet to fluid flow from the gas inlet.
