Abstract: A primary groove, into which a primary vane is slidably fitted, and a primary rotor-side suction passage, which conducts refrigerant of a shaft-side suction passage of a shaft to a primary compression chamber, are formed at a primary rotor. The primary groove is shaped into a form that extends from an inner peripheral side toward an outer peripheral side and extends toward a rear side with respect to a rotational direction, and the primary rotor-side suction passage is shaped into a form that extends from the inner peripheral side toward the outer peripheral side and extends and tilts toward a front side with respect to the rotational direction. A fluid outlet of the primary rotor-side suction passage opens at a location that is immediately after the primary groove on the rear side of the primary groove with respect to the rotational direction.

Abstract: A rotary compression mechanism includes: a shaft attached to a casing; a drive cylinder rotatably supported on the shaft; a rotor provided inside the drive cylinder; a transfer mechanism connecting the drive cylinder and the rotor in rotational motion at a constant speed; and a partition plate dividing a space defined between an inner periphery of the drive cylinder and an outer periphery of the rotor. The rotor has a second rotation center which is eccentric with respect to a first rotation center of the drive cylinder such that the outer periphery of the rotor is in contact with the inner periphery of the drive cylinder at a contact portion. The partition plate has a structure by which one end of the partition plate is let in and out in a vicinity of the inner periphery of the drive cylinder or in a vicinity of the outer periphery of the rotor.

Abstract: A rotary cylinder type compressor includes: a cylinder that is rotatably placed in an inside of a housing; a rotor that is placed in an inside of the cylinder and is rotatable about an eccentric axis that is eccentric to a rotational central axis of the cylinder; and a partition member that partitions a working chamber formed between an outer peripheral surface of the rotor and an inner peripheral surface of the cylinder into a suction space and a compression space. When a pressure of fluid in the compression space is equal to or larger than a reference pressure, a contact stress, which is exerted at an adjoining portion between the outer peripheral surface of the rotor and the inner peripheral surface of the cylinder, is increased in comparison to a case where the pressure of the fluid in the compression space is smaller than the reference pressure.

Abstract: A rotating cylinder type compressor includes: a cylinder having a cylindrical shape and rotating about a central axis; a first rotor and a second rotor each having a cylindrical shape and rotating about an eccentric axis eccentric to the central axis of the cylinder; a shaft; a first vane; and a second vane. The first vane is slidably fitted to a first groove portion defined in the first rotor to define a first compression chamber. The second vane is slidably fitted to a second groove portion defined in the second rotor to define a second compression chamber. The first rotor and the second rotor are arranged in an extending direction of the central axis of the cylinder.

Abstract: In a cylinder rotary compressor, a shaft-side suction passage for circulation of a refrigerant is formed within a shaft that rotatably supports a rotor. A rotor-side suction passage is provided within the rotor so as to guide the refrigerant flowing out of shaft-side outlets formed at the outer peripheral surface of the shaft to a compression chamber. Furthermore, a rotor-side concave portion is formed at an inner peripheral surface of the rotor. A space provided within the rotor-side concave portion forms a rotor-side communication space with an appropriate shape and a capacity enough to make the shaft-side outlets communicate with a rotor-side inlet of the rotor-side suction passage, regardless of the rotation of the rotor.

Abstract: A cylinder-rotation-type compressor includes a discharge valve that is disposed in a cylinder and configured by a reed valve, a valve body portion that closes a discharge hole provided in the cylinder, and a support portion that couples the valve body portion with a fixing portion fixed to the cylinder. A shape of the valve body portion and a shape of the support portion are substantially symmetrical with respect to a line segment extending in a radial direction of a rotating axis. The valve body portion is disposed on a radially outer side of a connection portion of the fixing portion and the support portion.
