Abstract

PURPOSE:To avoid an overload on a bearing and provide compact constitution by converting a force acting on a rotor through differential pressure of a pump acting on the outer peripheral surface of rotor to a moment force having the rotor side end face of bearing as a fulcrum. CONSTITUTION:A rotor 13 in pumping operation is rotated counterclockwise to be pressed in the direction X by pumping operation pressure. Then, a main shaft 17 of the rotor 13 is inclined about a fulcrum of a bearing 11 of a rotor case so that the rotor 13 is pressed against the proximity of a discharge port 22 of a lid sliding plate 21. To balance the moment of rotor 13, the discharge port 23 side end face of rotor 13 is pressed axially and reversely the intake port 22 side end face of rotor 13 is adsorbed axially.
