Abstract

PURPOSE: To prevent overheating and the lowering of performance eliminating friction between grooves and vanes by operating vanes with a rod projected therefrom having the tip thereof mounted on the shaft.
CONSTITUTION: A vane pump is so arranged that the tip of a rod each projected from vanes 1 is mounted on a shaft thereof in such a manner as to be free to move without supporting the vane 1 with any groove thereby eliminating friction between the groove and the vane. This can prevent overheating and the lowering of the performance as the groove of a rotor 3 is required to support the vane 1, hence producing no friction. In this case, a circular arc is made between points 8 and 9 and 10 and 11 of an outer case 5 not illustrated centered on a shaft 4. Additionally, effect of the liquid pressure on the movement of the vane 1 can be prevented if the distances from two points to the vane shaft 4 are made equal. One is a point 6 of contact between the outer case 5 and the vane 1 and the other is a point 7 at which the vane 1 and the rotor 3 are respectively separated to the right and left.
