摘要： The present invention enables a scroll fluid machine to have a maximum design volume ratio without increasing an outside dimension of scrolls and allows the basic spiral curve of the scroll to be configured with simple curves. The basic spiral curve of a scroll wrap comprises a group of concentric semicircles, a group of circular arcs having a center different from that of the group of semicircles, and a group of straight lines or curves connecting the group of semicircles and the group of circular arcs together, and a diameter of the outer-most circumferential semicircle of a fixed scroll member is twice as large as radius of the outer-most circumferential circular arc of an orbiting scroll member. In addition, an outer diameter of an end plate of an orbiting scroll is equal to an outer diameter of the outer-most circumferential wrap of the scroll.

摘要： A compressor includes a compression chamber for compressing working fluid within an inside thereof, a discharge port, through which the working fluid flows out from the compression chamber, and a discharge valve for opening or closing the discharge port. The discharge valve includes a valve seat portion provided in the discharge port and having a tapered surface, so that a cross-section area of the discharge port comes to be large from a side of the compression chamber. The valve has a projection portion having a tapered surface in contact with the tapered surface of the valve seat portion. A spring is provided on a member formed in one body with the valve seat portion, for positioning the valve to the valve seat portion, wherein clearance volume of the discharge port is reduced, so as to improve the performances thereof.

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.
