Device for high pressure fuel injection

摘要

In the high pressure fuel injection pump, the feed (3) has a feed channel (2) and the return (5) for surplus fuel has a parallel feedback channel (4), in a fuel supply component. The non-return valve (8) is inserted across the flow direction of the return (5), supported by a side wall in the return (5). A wall, at a gap from the fuel feed (3), forms an outer wall (7) of the component.
