Abstract
PURPOSE: To reduce vibration and noises during the operation of a pump,by opening communication holes through a rotor so that vane chambers in symmetric positions in the suction and the discharge processes are connected to each other to prevent cavitation from occurring in the vane chamber in the suction process.
CONSTITUTION: The cavities 5a, 5a of vane chambers 5, 5 in symmetric positions are connected to each other through communication holes 22 opened through a rotor 1. As a vane 6 in a position V in the discharge process is gradually pushed into the cavity 5a, high-pressure liquid at the side of an outlet port is introduced through a recess 7 and filled at sufficiently high pressure into the cavity 5a in the symmetric position II in the suction process through the communication hole 22 in the direction of an arrow A to appropriately heighten the pressure of the vane chamber 5.
