Priming pump for vehicle fuel diversion circuit comprises deformable casing connected to inlet and outlet ends fitted with movable valve, ends arranged to provide greater outflow rate than inlet flow rate

摘要

The priming pump comprises a deformable casing connected to an inlet end (12) and an outlet end (13) each fitted with a movable valve (19). The ends are arranged so that when the valves are in the sealing position the outlet end has an outflow rate greater than the inlet end flow rate. Each end comprises a hollow body (14) defining a cavity (16) delimited by a back (21) comprising an orifice (20) through which emerges a connector (15) for connecting the pump to a circuit. The ends also have cover (17) comprising an orifice (18).
