Claims

[Scope of utility model registration request]

In an accumulator fuel system for an internal combustion engine that adjusts the fuel injection amount by changing the lift of the discharge valve of the fuel control valve, the roller at the outer end is inserted into the housing and has a female threaded part at the inner end. A sliding tube that reciprocates in contact with the control cam, a pinion housed in the housing and rotated by the operation of the rack, and a male threaded portion at one end screwed into a female threaded portion of the sliding tube, the other end. A fuel injection device characterized by comprising a jack fitting that is fitted into the pinion so as to be movable in the axial direction and interlocked in the circumferential direction, and that changes the lifting height of the discharge valve by displacement in the axial direction due to rotation of the pinion. Volume adjustment device.
