Japanese Patent JPH1193862
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the assembling property by reducing the number of pump part items. SOLUTION: This variable-displacement pump is provided with a cam case 23 rockably supporting a cam ring 34 biased to one side by a rotor 33 having a vane 33a and forming a pump chamber between it and the rotor 33 while a rocking pin 35 arranged along the axial direction serves as a fulcrum and functioning as an intermediate body. A front body 21 and a rear body 22 forming a pump body and journalling the rotary shaft 40 of the rotor 33 are arranged on both end sides in the axial direction of the cam case 23. The rocking pin 35 is used as one positioning means for positioning both bodies 21, 22 and the cam case 23 at the time of assembling. A reamer bolt 45A is used for at least one of the fastening means integrally connecting both bodies 21, 22 and the cam case 23 as another positioning means.
