摘要： A refrigerant compressor is provided that can be assembled easily and can quickly discharge lubricating oil that leaks from contact sliding parts of its mechanical seal so as to prevent the oil from turning into sludge around the stationary ring. In a refrigerant compressor (1) in which a mechanical seal (30) which shaft seals the inner side and the outer side of a housing (2) is installed at a portion of the housing (2) through which a rotating shaft (25) penetrates, a mechanical seal (30) comprises a stationary ring (41) securely fastened to the inner circumferential surface of a boss portion (7A), a rotary ring (44) securely fastened to the outer circumferential surface of the rotating shaft (25) to the inside of the stationary ring (41) so as to face the stationary ring, whereby sliding contact is formed between sides of the stationary ring (41) and the rotary ring (44). The inner circumferential surface of the boss portion (7A) to the outside of the stationary ring (41) is provided with an inclined portion (49A) over the entire circumference or at least the gravitationally lower portion of the inner circumferential surface, which enlarges from the stationary ring (41) side toward an oil discharge hole (51) to the outside of the stationary ring (41).

摘要： A scroll compressor having an improved compression efficiency by optimizing a step mesh gap in an operating state is provided. The scroll compressor having a step-like shape has a step-mesh-gap set value (Hf) occurring between step side surfaces of a connecting wall 12h of a fixed scroll 12 and a connecting edge 13e of a revolving scroll 13 and a step-mesh-gap set value (H0) occurring between step side surfaces of a connecting wall 13h of the revolving scroll 13 and a connecting edge 12e of the fixed scroll 12, and a fixed-side set value (Hf in the example shown in the drawing) for when the two move close together due to the revolving scroll tilting by receiving gas pressure during operation is set greater than that (H0 in the example shown in the drawing) for when the two move apart.
