Abstract: PROBLEM TO BE SOLVED: To improve compressor efficiency and reliability by reducing a surface roughness Ry value of a vane of a cylinder, since a shape and surface roughness are not specified on a vane groove of a mating cylinder only by paying attention to the surface roughness of a suction side of the vane side surface, and since the surface roughness of a certain degree is secured by generally polishing a vane side surface, in a conventional constitution.
SOLUTION: A sliding loss of the vane can be reduced by being characterized by reducing the surface roughness Ry value more than the side surface 7a of the suction side of the vane groove 7 by being processed in a range of the surface roughness Ry value of Ry=0.1 to 0.9 μm, by processing a side surface 7b of a discharge side of the vane groove 7 of the cylinder 1.

Abstract: PROBLEM TO BE SOLVED: To eliminate leakage of a refrigerant so as to prevent performance degradation caused by lowering of volumetric efficiency and to attain high efficiency under a wide range of operating conditions.
SOLUTION: A step having a certain height is provided so that an area ranging from the inner periphery of an annular oil supply groove 33 of a fixed scroll 14 to the outer periphery of an end plate of the fixed scroll 14 is depressed, whereby a sliding surface 14a is arranged inside an envelope line of a swirling scroll 15 and is higher than a fastening surface 14b with respect to a main bearing member 13. Accordingly, when the sliding surface side outer peripheral edge portion of a swirling scroll end plate moves in a swirling manner, it is possible to prevent the same from interfering with the fastening surface of the fixed scroll end plate, thereby reducing sliding loss.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor improved in reliability by preventing a fixed scroll and a rotary scroll from being seized.
SOLUTION: The inclusion of oil between the fixed scroll 2 and the rotary scroll 3 is promoted by reducing the height of a lap from the centerline of the lap toward the side surface of the lap in the thickness direction of the lap even when the axal gap between the fixed scroll and the rotary scroll is reduced. Since the shortage of oil film between the fixed scroll and the rotary scroll is suppressed even during a high speed operation and a high pressure-difference operation. Therefore, the rotary scroll and the fixed scroll are prevented from being seized.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor preventing seizure by inhibiting deformation of a fixed scroll due to thermal expansion and securing high reliability.
SOLUTION: Heat insulating material is installed at an anti-lap side of an end plate of the fixed scroll 2, heat conduction to a fixed scroll end plate from high temperature working fluid is inhibited to inhibit temperature rise of the fixed scroll 2 even during high speed-high differential pressure operation in which delivery temperature gets high, and deformation due to thermal expansion of the fixed scroll end plate and the fixed scroll lap is inhibited to prevent contact of a turning scroll 3 and the fixed scroll 2. Consequently, increase of input and seizure can be prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce leakage loss in a compression chamber formed by a fixed scroll and a turning scroll in a scroll compressor, along with enhancement of efficiency of a refrigerating air-conditioning apparatus and application of high-pressure refrigerants, such as carbon dioxide. SOLUTION: A tip seal storing groove 81 for storing a tip seal 80 is provided in a tip part of a spiral lap 13b of the turning scroll 13, and a plurality of communication passages 82, 83 for communicating the bottom face of the tip seal storing groove 81 with an inside region of a sliding partition ring 78 are installed inside the turning scroll 13. Due to high pressure from the inside region of the sliding partition ring 78 to a plurality of portions, the entire region of the tip seal 80 is securely pressed against the fixed scroll 12. Thus, during high pressure difference operation, leakage in the compression chamber 15 can be reduced to achieve the highly efficient scroll compressor. COPYRIGHT: (C)2009,JPO&INPIT
