ABSTRACT:
A fuel injection pump for internal combustion engines having a reciprocating pump piston and an annular slide displaceable on it, with a control bore that cooperates with a control recess on the pump piston, the recess communicates with a pump work chamber via a conduit. By means of location of control bores in the annular slide, the outflow stream is provided with the longest possible path until the outflow stream strikes the wall of the cylinder liner, in order to attain the freest and most unhindered possible stream course with reduced turbulence. Because the outflow stream strikes the hardened surface of the niche wall of the cylinder liner obliquely, cavitation damage is greatly attenuated or locally limited to sites of maximum resistance.
