Claims

[Scope of utility model registration request]

A rotor with a large number of vanes that are eccentrically arranged in a cylindrical hole formed in the machine body and can be slid in the direction of the half mold is provided to be freely rotatable, and the rotation of the rotor causes the large number of vanes to come into contact with the inner peripheral surface of the cylindrical hole. An air passage means is inserted through the cylindrical hole so that air can be taken in and discharged through the action chambers that are divided by sliding contact. The inner side of a sealing member made of an elastic material that has an annular groove formed therein to collect the lubricating oil flowing through the contact portion and flowing into the working chamber, and that contacts the outer periphery of the rotor shaft to prevent the lubricating oil from leaking to the outside. A buffer member is installed in the machine body so as to regulate the lubricating oil acting on the sealing member, and the lubricating oil is communicated with the contact area with the machine body on both sides of the rotor and the vane sliding groove of the rotor through a cylindrical hole in the machine body. An oil supply port that connects to the pressure source side of the rotor, and an oil discharge port that communicates with the gap and annular groove formed between the sealing member and the buffer member and connects to the low pressure side. machine.
