摘要 PCT No. PCT/DE93/00641 Sec. 371 Date Apr. 5, 1994 Sec. 102(e) Date Apr. 5, 1994 PCT Filed Jul. 21, 1993 PCT Pub. No. WO94/03722 PCT Pub. Date Feb. 17, 1994.A fuel injection pump for internal combustion engines, having a pump piston that moves in a cylinder liner and defines a pump work chamber with the cylinder. The piston has two control edges that cooperate with a control opening in the cylinder liner. One, control edge is oblique, disposed on the jacket face and communicates continuously with the pump work chamber which controls the end of supply. A first upper control edge formed by the face end of the pump piston, controls the supply onset upon overtaking the control opening. For a load- and temperature-dependent shift of the supply onset toward early, the face end of the pump piston has a first region (B), axially indented in the direction of the cam drive, forming a second control edge, which is separated from the flat region (A) on the face end by a longitudinal groove and in the first region a second region (C), indented via shoulders is disposed in turn in the direction of the cam drive, with a third control edge.
