    摘要: A multiple-vane rotary compressor having a cylinder bore profile especially designed to reduce the fluctuation in the overall drive torque applied to the rotor shaft. The cylinder bore profile is configured and designed so that the individual drive torque applied to an individual vane during the compression and delivery strokes varies along a drive torque-vane angle curve which approximates an isosceles triangle having a lower side corresponding to a range of angle of 180.degree.. The cylinder bore profile includes, for a profile section extending through an angle of 180.degree., a first region (i) in which the amount of vane projection is held substantially constant at a maximum value (D), a second region (ii) in which the amount of vane projection decreases at a higher rate, and a third region (iii) in which the amount of vane projection decreases to zero at a lower rate, the imaginary transitional point (A.sub.3) between the second and third regions being located at an angular position of 90.degree..

    摘要: A scroll type compressor comprises a fixed scroll having an end plate and a spiral element. The spiral element of the fixed scroll is integrally coupled to the inner wall of a housing. A movable scroll has an end plate and a spiral element, and faces the fixed scroll, with a plurality of fluid pockets formed between the movable scroll and the fixed scroll. When the movable scroll makes an orbital movement around the axis of the rotary shaft, refrigerant gas is led into the fluid pockets from outside the movable scroll. As the fluid pockets move toward the center of the movable scroll the fluid pockets decrease in volume, thereby compressing the refrigerant gas. A suction chamber which receives the refrigerant gas from outside the housing is formed between the movable scroll and the inner wall of the housing. A passage is formed in at least one of the inner wall of the housing, the connecting section and the end plate of the movable scroll. This passage permits the refrigerant gas to flow into the fluid pockets from the suction chamber in order to reduce any difference in pressure of the refrigerant gas in the suction chamber and in the fluid pocket.

    摘要: A vane type rotary compressor has a housing and end plates secured thereto to cooperate therewith to define a cylindrical bore in which a rotor is eccentrically mounted for rotation with vanes slidably mounted in vane grooves formed in the outer periphery of the rotor. A lubricant groove is formed in the inner surface of one end plate and so disposed as to be brought into communication with the inner end portions of the vane grooves pertaining to vanes defining working chambers when in their intake phases. The lubricant groove is connected by a passage with a discharge chamber of the compressor so that fluid pressure is fed into the inner end portions of the vane grooves to urge the vanes into sealing engagement with the inner peripheral surface of the cylindrical bore. A valve is provided to disconnect the discharge chamber from the lubricant groove during normal compression operation of the compressor.

    摘要: A variable discharge rotary compressor has a housing, a rotor disposed therein and vanes mounted on the rotor to cooperate with the housing and the rotor to define variable volume working chambers disposed close to and separated from an intake chamber by an end wall in which a communication passage is formed to communicate the working chambers with the intake chamber. The communication passage is located at a point where the working chambers are in their compression strokes. A valve is disposed in the communication passage to control the communication between the compression chambers and the intake chamber and is operative to communicate the compression chambers with the intake chamber to permit a part of the fluid in the compression chambers to be returned therefrom back into the intake chamber when the discharge of the compressor exceeds a predetermined discharge requirement. The communication passage is of a very short length so that the fluid passing through the communication passage toward the intake chamber can be prevented from being unduly heated by the heat of the compressor body.

    摘要: A rotary compressor including a housing having therein a cylindrical bore, and end plates closing opposite ends of the bore and supporting a rotary shaft supporting in turn a rotor formed with a plurality of circumferentially spaced vane grooves. A vane is slidably received in each vane groove and cooperates with the adjacent vane to define therebetween a working chamber. An oil groove is formed on a surface portion of one of the end plates which surface portion is located opposite to a path along which the bottoms of the vane grooves pass, at least in a position where the working chamber has its volume increased. A cover is attached to the one end plate to define therebetween a discharge chamber receiving therein fluid compressed by the vanes. A passage communicates an oil revervoir defined at the bottom of the discharge chamber and the axial end face of the shaft opposite to the one end plate with each other. The oil in the oil reservoir is introduced into the oil groove through the passage, along the outer periphery of the shaft, and through a gap between the rotor and the one end plate.

    摘要: In a rotary vane-type compressor the rotor, the housing and the side plates are made of the same kind of material as one another. A plurality of vane grooves the length of each of which is as long as the thickness of the rotor is provided on the rotor. A set of vanes which is made of a different material than the rotor, more particularly a material the coefficient of thermal expansion of which is larger than that of the rotor, is received in the vane grooves in such manner that the end faces thereof face against the side plate. And the width of the vanes longitudinally of the rotor is determined as follows. The width is slightly less than the thickness of the rotor when the temperature there of is less than normal, but when the temperature becomes high the vane width becomes slightly greater than the thickness of the rotor because of the difference of the coefficients of thermal expansion.

    摘要: A rotor cover is disposed at one end surface of a rotor which has a ring-shaped locking ridge on the end surface thereof. The locking ridge has an outer peripheral surface fitted in a locking groove in the rotor cover. A holder is held against an inner peripheral surface of the locking ridge. With this arrangement, the diameter of the rotor is kept constant at all times, and so is the gap between the rotor and the housing, thus preventing scuffing of the rotor and the housing.
