Claims

[Claims for Utility Model Registration] As the rotor fits inside the casing and rotates,
It has a projecting object drive mechanism that fixes the periphery of the projecting object and causes the projecting object to appear and disappear by means of a working fluid supplied through a support porous plate, so that the projecting projecting object moves while being in close contact with the inner surface of the casing. In a rotary pump, the side of the circumferential sliding surface of the rotor with the casing that is open to the outside air is covered with a high viscosity lubricant at a higher pressure than the inside. A rotary pump that prevents leakage.
