Abstract

PURPOSE:To improve air tight and suction performance by providing a cover for a water chamber contiguous to a cam chamber of a main body, and providing the water chamber of a steam separated construction, while forming specified communicating holes and discharge openings at the uppermost side and the lowermost side of the cam chamber, respectively. CONSTITUTION:A driving shaft 1, a rotor 2, a vane 3, a mount 5, a side cover 6, a main body 7, a cover 8 for a water chamber, and a cover 11 are respectively formed independently. The cover 8 for the water chamber is provided contiguous to a cam chamber 17 of the main body 7 so as to be provided with a water chamber 20 of a steam separated construction. Water is usually supplied to the cam chamber 17 from a hole 25 communicated with the lowest side of the cam chamber 17 formed on the lower side of the water chamber 20, so that suction water head of a vane pump is kept highly. A discharge opening 27 opened to the uppermost side of the water chamber 20, is formed with a small diameter, so that pressure of the water chamber 20 is raised over a specified value whenever the inside of a vane pump is filled up with suction water. Thereby, improvement in air-tightness and suction performance is attained.
