Title: Distributor type fuel injection pump
Inventor: NOMOTO KATSUYA
IPC: F02M41/14
Filed: 1994-07-19
Abstract: PURPOSE:To provide an inner cam system distributor type fuel injection pump by which a drive shaft rotating position can be measured with high accuracy by a rotary position sensor. CONSTITUTION:Plungers 23 and 24 slidingly reciprocate in a guide hole 22 formed in the radial direction of a rotor 20. The plungers 23 and 24 integrally rotate with the rotor 20, and reciprocate in the guide hole 22 according to a cam profile of an inner cam 30 through rollers 28 and 29, and suck in and forcibly send fuel of a pressurizing chamber 25. Impact force generated in the inner cam 30 by jumping of the rollers 28 and 29 is damped and absorbed by a vibration absorbing member 53. A bolt 57 is inserted in bolt inserting holes 53c and 54c of a bracket 54 and the vibration absorbing member 53 by holding an idle condition. Therefore, the impact force generated in the inner cam 30 does not directly propagate to the bracket 54. Therefore, since vibration is hardly propagated to an engine speed sensor 50, a rotating position of a drive shaft 3 and the rotor 20 can be detected with high accuracy.
