プ。[Claims for Utility Model Registration] 1. A dispensing type fuel that sucks in, pumps and distributes fuel using a reciprocating and rotating plunger, and has a movable control sleeve on the plunger that changes the timing of opening the cut-off port. 1. A distribution type fuel injection pump, characterized in that the control sleeve is provided with a retaining piece, and a delay device is provided that comes into contact with the engaging piece and delays movement of the control sleeve. 2. The dispensing device according to claim 1 of the utility model registration, characterized in that the delay device has a piston that is displaced in response to pressure within the chamber, and the chamber behind the piston is communicated with the low pressure side through an orifice. type fuel injection pump. 3 The delay device is displaced by the pressure inside the chamber. It is characterized by having a piston that communicates with the chamber behind the piston through an orifice or communicating with the low pressure side by a servo piston that is displaced by the pressure inside the chamber. A distribution type fuel injection pump according to claim 1 of the utility model registration claim.
