DEVICE FOR CONVEYING FUEL FROM A TANK TO THE INTERNAL COMBUSTION ENGINE OF A MOTOR VEHICLE |
摘要 |
<p>An apparatus for pumping fuel from a tank (10) to the internal combustion engine (12) of a vehicle has a jet pump (24), which supplies fuel returning from the internal combustion engine (12) in a return line (22) together with fuel disposed in the tank (10) into a storage reservoir (14) of a fuel delivery unit (16). The invention proposes embodying a restriction (23) for the fuel between a seat edge (31) and a spring-loaded ball (32). In addition, inlet openings (39) for the fuel disposed in the tank (10) are embodied in the vicinity of the restriction (23). The apparatus has the advantage of a high delivery output, a compact design, and a delivery onset even when there are relatively low return quantities. Furthermore, fuel is prevented from flowing back into the return line (22).</p> |
