Abstract (en)
A device comprising a cup-shaped body (1) defining a fuel chamber (4) communicating with a fuel inlet hole (5) and with a fuel outlet hole (6), which outlet hole (6) is controlled by a plunger (7) connected to a deformable diaphragm (8) subjected to the action of a spring (9) designed to normally maintain the plunger (7) against a seat (10) and so close the outlet hole (6). The fuel inlet hole (5) communicates with an inlet fitting (12) projecting from the bottom wall (3) of the body (1) and connectable in fluidtight manner inside a seat (13) on the manifold. The fuel outlet hole (6) communicates with an outlet fitting (15) projecting from the lateral surface (16) of the body (1) and having its axis perpendicular to the longitudinal axis of the body (1).
