Operation manner and the said liquid pressure operation type fuel pump of liquid pressure operation type fuel pump for internal combustion engine

摘要

(57) Abstract The liquid pressure operation type fuel pump for the internal combustion engine (1) has the pump piston (39) Drive to the front at emission distance, by the actuator piston (36). At between each injection distance, the pump piston (39) is reset to fixed starting position by the operation of pressure of the fuel operation to the end face (61 and 62) of the pump piston inside the pump chamber (52). The emission tonnage of the fuel pump is controlled electronically by supplying the liquid pressure fluid vis-a-vis the pressure chamber which is cut off at the point in time when the pump piston delivers the tonnage of desire by the control valve (11). The pump cylinder (25) and the actuator cylinder (24) are the separate device, these are separated mutually by the separable component (26) of center.
