Beschreibung
Zusammenfassung:	PURPOSE: To prevent variations in injection by forming a collar which is fitted into the penetrating passage of a valve seat body, in such a way that the collar is integrated with the head of a valve closure member which can be seated on the valve seat of the valve seat body and which is energized by a compression spring in a closing direction, and forming a spirally extending cutout in the collar. CONSTITUTION: A pressure valve 1 provided between the delivery side conduits 7, 7' of a fuel injection pump which lead to a fuel injection nozzle 8 has a valve closure member 21 which can be seated on the valve seat 19 of a valve seat body 14 and which is energized by a compression spring 26 in a closing direction. A collar 30 which is fitted into the penetrating passage 20 of the valve seat body 14 is formed integrally with the head 24 of the valve closure member 21 and a guide portion 31 is connected to the collar 30. The guide portion 31 has a guide rib 34 formed by a cutout 33. In this case, the collar 30 is divided into a return suction collar 35 and a control collar 36 and a circumferentially spirally extending cutout part 38 is provided in the control collar 36, the height of the control collar 36 being specified by the control edge of the cutout part 38 facing the head 24.
