Abstract
PURPOSE:The electric centrifugal pump is combined with the jet pump and the by-pass passage can be open and close operated and at the same time the valve device capable of controlling the close is installed. By doing so, the pump device is compact sized. CONSTITUTION:A diffused 4 is installed inside a jet body 2 connected with the suction side of an electric centrifugal pump 1 and a by-pass passage 7 capable of connecting both the suction side and discharge side of the jet body 2 is also installed. This by-pass passage 7 in accordance with the pressure difference between suction side and discharge side of the jet body 2 and that the valve device which works for the releasing direction so as to control the close, is provided. This valve device is composed of the valve body for open and close of the by-pass passage 7 and of a coil spring 5 actuating for the releasing direction of this valve body.
