摘要： In a displacement type fluid machine wherein a space is formed by the inner wall surface of a cylinder and the outer wall surface of a displacer when the center of the cylinder is located on the center of the displacer, and a plurality of working chambers is formed when the positional relationship between the displacer and cylinder is for a gyration, the wear is reduced between the cylinder and displacer. Sliding portions between the displacer 5 and a cylinder 4 are fed with a lubricating oil 12 by forming an oil-feeding groove 5c in the surface of the displacer 5 so as to extend from the central portion of the displacer 5 to the vicinity of a suction port 7a, and feeding the lubricating oil 12 from the central portion of the displacer 5, so that the wear can be reduced.
