ABSTRACT:
A fuel injection pump for compressed air injected internal combustion engines with a pump piston and with a control slide valve member coaxially arranged to each other in a given pump cylinder, of which the pump piston controls a fuel control bore in the pump working space and actuates the control slide valve member which is under the force of a spring; the control slide valve member which rests continuously on the pump piston and possibly may be made in one piece therewith includes in its lower half facing the pump piston a recess, preferably rounded-off, that extends in the direction of movement of the control slide valve member and that terminates at a slight inclination in the direction of the outer circumference of the control slide valve member; a bore arrangement is provided in the housing part in which the control slide valve member is longitudinally displaceably guided by means of which the pump pressure space is connected with the pump working space alternately by way of a bore arrangement in the control slide valve member or by way of the recess.
