Abstract: PROBLEM TO BE SOLVED: To solve a problem that noise is increased by the vibrations of a projection formed by expanding part of a jutting plane part of the cover during operation due to no fixation with a bolt or the like and the insufficient rigidity of the projection formed by expanding part of the jutting plane part of the cover provided so as to prevent oil from being discharged in a rotary compressor.
SOLUTION: In a rotary compressor, a cover 20 contains a plane part 32 projecting to an outer peripheral part. The plane part 32 covers the position corresponding to a communication hole formed in a position facing a blade 10 and includes a projection 31 in the plane part 32 so that the rigidity of the plane part 32 is enhanced to prevent the plane part 32 from being vibrated during operation. As a result, noise can be reduced.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that when the thickness of a valve mounting section is set up to be thin in order to improve the efficiency of a compressor in a conventional structure and compression efficiency is improved by decreasing a dead volume of a discharge outlet, since the thickness of a valve mounting section becomes thin and differential pressure between discharge pressure and suction pressure is made to act on the outside and the inside of an upper bearing, a section facing an internal side of a cylinder inner wall of the thin valve mounting section expands inward by being pushed by the differential pressure, and brings into contact with an end face of a piston, and worn.
SOLUTION: A rotary compressor can eliminates the section facing an inner side rather than the cylinder inner wall 3a of the valve mounting section 6 by forming the valve mounting section 6 except a discharge outlet ring 14 at an outer side rather than the cylinder inner wall 3a.

Abstract: PROBLEM TO BE SOLVED: To suppress decrease in performance and improve reliability by uniformly forming minute recesses on a face on a wrap side of an end plate of a scroll.
SOLUTION: Liquid including hard fine particles is uniformly injected by gas pressure from an injection hole of a nozzle 34 having the longitudinal length longer than the outer diameter of the end plate 15a of the turning scroll 15 to the face on the wrap side of the end plate 15a of the turning scroll 15, and the nozzle 34 is rotated around the center of the end plate 15a of the turning scroll 15. Due to this, even when the height of the wrap 15b is high and it is difficult for the hard fine particles to abut on a winding start part 15c of the wrap 15b of the face on the wrap side of the end plate 15a, the moving speed of the nozzle 34 in the winding start part 15c of the wrap 15b is slower than that in an end plate outer peripheral flat face 15d. Therefore, process time per unit area can be elongated and the hard fine particles can be uniformly injected to the face on the wrap side of the end plate 15a of the turning scroll 15, so as to uniformly process the minute recesses 33.

Abstract: PROBLEM TO BE SOLVED: To increase the reliability of a fixed scroll and a rotary scroll of a scroll compressor to match the compressor to recent refrigerating air conditioners increased in efficiency and life and using a high-pressure refrigerant such as carbon dioxide.
SOLUTION: A communication passage 80 allowing a high-pressure part 30 on the inside of a sliding partition ring 78 to communicate with a compression chamber 15 is formed in the rotary scroll 13. An opening 81 on the compression chamber 15 side of the communication passage 80 is so formed at the lap end 13b of the rotary scroll 13 as to face discharge ports 18 at the center of the fixed scroll 12. Since the lap end 13b of the rotary scroll 13 is prevented from coming into nonuniform contact with the end plate 12a of the fixed scroll 12 when the scroll compressor is under high load, the high reliability of the scroll compressor can be realized.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor having both high reliability and high efficiency.
SOLUTION: The surface hardness of the upper surface 9d of the lap of a rotary scroll is made smaller than that of the other surfaces than at least the upper surface 9d of the lap of the rotary scroll. Since the sliding surface of the rotary scroll is fitted earlier and the deterioration of input can be avoided even if the upper surface 9d of the lap of the rotary scroll is brought into slidable contact therewith under high temperature, high compression ratio operating conditions. Consequently, the scroll compressor having high reliability and high efficiency can be provided.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor capable of achieving both of securing force and seal performance without inducing a cost increase due to addition of parts or an efficiency degrading due to a residual stress.
SOLUTION: In a fixing surface 25 at which a fixed scroll 6 and a body frame 5 are fixed in close contact together, a surface roughness of a fixing surface 25b of the body frame or a fixing surface 25a of the fixed scroll is set greater than the surface roughness of the other fixing surface. Thus, numerous micro protrusions 27a are formed on the fixing surface of the greater roughness side. The micro protrusions 27a are fitted into the other securing surface with a bolt-tightening force to suppress a slip of the fixing due to a radial load, and the seal performance of the securing surface 25 can be secured as well.
