摘要： 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.

摘要： 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.

摘要： 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.

摘要： A first connection portion is located on one side of a predetermined flow path member in a plane direction. The predetermined flow path member and another flow path member are bonded by brazing at the first connection portion. A second connection portion is located on the other side of the predetermined flow path member. The predetermined flow path member and another flow path member are bonded by brazing at the second connection portion. A brazing material layer extends over the predetermined flow path member, the first connection portion, and the second connection portion. A hilling portion is a portion of the predetermined flow path member. The hilling portion is curved to protrude toward a side on which the blazing material layer is provided. The hilling portion extends along a direction in which the first connection portion or the second connection portion extends.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A rotor is placed on one axial side relative to a passage hole forming portion at an inside of a housing. A differential pressure device is placed on the one axial side relative to the rotor and has a pressure chamber. The housing has: a one-side space that is placed on the one axial side relative to the rotor; and at least one other-side space that is placed on another axial side, which is opposite to the one axial side, relative to the passage hole forming portion. The differential pressure device generates an urging force that urges the rotor against the passage hole forming portion by a differential pressure between a pressure in the pressure chamber and a pressure in the one-side space in a case where a pressure in the at least one other-side space is higher than the pressure in the one-side space.
