Abstract (en)
[origin: DE19848040A1] A pump housing (2) has a first plate (16) to seal it against an internal chamber (10), which is covered by a second plate (18). Both plates engage on each other full-surface. A section of a first channel (29) containing fuel at under pressure, passes through the first plate between pump housing and second plate. A second back pressure valve (12) is located between first plate and pump housing. A second channel (31) containing fuel at high pressure, extends between the second valve and a cylinder chamber (17) in the first plate.
