Abstract (en)
In order to isolate the injection pumping element (2) in a conventional high pressure fuel injection system from the fuel, a pressure exchanger, consisting of two chambers interconnected by an elastic member (14) such as a membrane or bellows, is installed in the delivery conduit between pumping element (2) and injector (9). This allows the pumping element (2) to work with any suitable fluid, e.g. one with better lubrication properties than the fuel itself. The pressure impulses from the pumping element (2) are thus transmitted through the elastic member (14) to the fuel which, through suitable check valve means, (17, 18) is pumped to the injector (9).
