Abstract (en)
[origin: EP0931928A1] The system consists of a calibrated valve (6) in the excess fuel return pipe (5) in parallel with and close to the injection pump return port (4b), designed to give an increase in pressure in the pump port, and a normally-open one-way valve (7). The one-way valve (7), which is springloaded, is closed when the pressure in the port rises above that in the fuel feed pipe (2) before its non-return valve (3).
