Claims

[Claims for Utility Model Registration] 1. A cylindrical cylinder having cooling fins or a cooling jacket on its outer periphery; formed at a symmetrical position with respect to the center on the inner wall surface of the cylinder, and becoming narrower toward the center, and a sector-shaped valve seat having a suction port at the center, a suction passage communicating with the suction port on the side, and a discharge port at the center and a discharge passage communicating with the discharge port on the side, shifted in position in the axial direction; a carbon seal fitted in a groove formed in the axial direction of the inner surface of the key part of the seat; and a suction valve and a discharge valve provided in each suction passage and discharge passage via valve holders on the side surface of the fan-shaped valve seat. and; a pair of valves that are swingably provided at the center of the cylinder at both latch portions of the fan-shaped valve seat via carbon seals, and swingably slide and seal with the inner wall surface of the cylinder via a carbon seal at the tip. An oscillating oil-less compressor characterized by performing suction compression using a rotor having vanes. 2. A cylindrical cylinder having cooling fins or a cooling jacket on its outer periphery; On the inner wall surface of the cylinder, the cylinder becomes narrower toward the center, and has a suction port in the center and a suction passage communicating with the suction port on the side, and in the axial direction. a fan-shaped suction/discharge valve seat with a cross section having a discharge port in the center and a discharge passage communicating with the discharge port on the side with shifted positions; provided at a position symmetrical to the fan-shaped suction/discharge valve seat on the inner wall surface of the cylinder; It gets narrower towards the center,
and a fan-shaped suction valve seat having a suction port in the center and a suction passage communicating with the suction port on the side; a carbon seal fitted in a groove formed in the axial direction of the inner surface of the latch of the fan-shaped valve seat; ; A suction valve and a discharge valve are provided in the suction passage and the discharge passage, respectively, via valve holders on the side surfaces of the fan-shaped valve seat; A rocking valve is provided at the center of the cylinder at both latch portions of the fan-shaped valve seat via carbon seals; A rotor having a pair of vanes that are movably provided and swing in a slidable and sealing manner with the inner wall surface of the cylinder via a carbon seal at the tip; passing through the center of the rotor and located in the axial direction; A swing type oil-less compressor characterized by having one or more through holes bored at different positions; and communicating two chambers at corresponding positions.
