Claims

[Scope of utility model registration request]

When the oscillating rotor fitted on the eccentric shaft is hermetically inserted into the sealed space formed by the cylinder, upper bearing, and lower bearing, the oscillating rotor is partitioned by a radial partition plate, and the oscillating rotor is In an oscillating fluid machine in which fluid is sucked and discharged by performing a dynamic motion and changing the volume of each sealed space partitioned into four by the oscillating rotor and a partition plate, the discharge ports of both compression chambers and the a first member which is located at the opposite position and is slidably inserted into a radial sliding groove provided in the boss portion of the cylinder and the lower bearing, respectively, and whose tips abut the ring-shaped portions of the rocking rotor; A second press plate is provided on the lower bearing, and transfers the compression chamber pressure outside the ring-shaped portion of the rocking rotor to the first press plate, and transfers the compression chamber pressure inside the ring-shaped portion of the rocking rotor to the first press plate. An oscillating fluid machine characterized by comprising first and second communication holes each introducing back pressure into the second press plate.
