Abstract

Described herein is a pump unit (1) for supplying fuel, particularly diesel oil, to an internal combustion engine. The pump unit (1) includes a pump housing (2), a delivery passage (3) formed in the pump housing (2) for supplying the fuel to the internal combustion engine and a check valve (9) positioned in the delivery passage (3). The check valve (9) includes a plug (10) that is movable between a position in which the plug (10) opens the delivery passage (3) and a position in which the plug (10) closes the delivery passage (3). The check valve (9) further includes a first annular conical seat (8) formed in the delivery passage (3) to receive the plug (10) after its movement from the open to the closed position. The pump unit (10) further includes a stop element (11) fitted in the delivery passage (3) and provided with a second annular conical seat (14) for receiving and retaining the plug (10) after the movement of the latter from the closed to the open position.
