Abstract

A pump unit for supplying fuel, preferably diesel oil, to an internal combustion engine is provided with a check valve (9), which is positioned in the passage (3) for delivering the fuel to the internal combustion engine and which is provided with a plug (10) which is movable between a position in which it opens the delivery passage (3) and a position in which it closes the passage, a stop element (11) being fitted in the delivery passage (3) to form a seat (14) for receiving and retaining the plug (10) after the opening of the check valve (9).
