Abstract

PURPOSE:To prevent a pump leak or ganeration of noise due to chattering of vanes, by partially providing slotted parts respectively to joined parts in two sheets of the vanes in an oil passage and applying delivery pressure to a back side of the vane then pressing the vane to surfaces of a cylinder wall. CONSTITUTION:Delivery oil is guided to the center portion of a pump rotor 10, and a vane sliding in a slit 13 is divided into two parts 14, 14', then slotted parts 31, 31' are provided in a jointed part of the vanes 14, 14'. In this way, delivery pressure of a pump is applied to back sides of the vanes 14, 14' to both press the vanes 14, 14' to wall surfaces of a cylinder 1 with sufficient strength of force and increase centrifugal force in accordance with rotary motion. As a result, the pump can be operated under such a condition that ends of the vanes 14, 14' are completely pressed to the wall surface of the cylinder 1. Accordingly, a leak of the pump can be eliminated simultaneously a tapping noise of the cylinder 1 caused by chattering action of the vane can be reduced, capable of improving performance of the pump.
