Claims

[Scope of utility model registration request]

A pair of slides protrude and retract along the guide groove so that their tips are in sliding contact with the sliding surfaces of the cylindrical portion of the rocking rotor, and partition the annular space between the inner circumference of the cylinder and the lower bearing boss into a suction space and a compression space. In an oscillating fluid machine equipped with a movable partition plate, an oil supply passage is provided in the space behind the guide groove of each of the sliding partition plates for guiding refrigerating machine oil sucked from the bottom of the housing through a refrigerating machine oil suction pipe, and An oscillating fluid machine characterized in that each of the oil supply passages is provided with a backflow prevention means.
