Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/239678
Kind Code:
A1
Abstract:
In a scroll compressor according to the present disclosure, when a crank angle of 0° is set to the time when refrigerant confinement is completed, the shortest distance Ls is greater than the minimum shortest distance Lα, Lα being, for the crank angle α > 0°, the shortest distance (compression chamber seal length) from a point where a fixed scroll wrap 124b and an orbiting scroll wrap 126b are in contact with each other on the outermost circumference to an inner circumferential edge 124d of an annular lubrication groove 124c, the shortest distance Ls being, for a crank angle of 0°, the shortest distance from the point where the fixed scroll wrap 124b and an orbiting scroll wrap 126b are in contact with each other on the outermost circumference to the inner circumferential edge 124d of the annular lubrication groove 124c and the shortest distance (intake part seal length) from an outer circumferential edge 128f of an intake part 128c to the inner circumferential edge 124d of the annular lubrication groove 124c. This arrangement provides a scroll compressor capable of both suppressing lowered compressor efficiency due to refrigerant and oil leakage and also reducing sliding loss.
