Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/216098
Kind Code:
A1
Abstract:
This scroll compressor has different discharge timings for a first compression chamber (S21) on the inner peripheral side of a fixed wrap (62) and a second compression chamber (S22) on the outer peripheral side, and has oil inflow grooves (80) in sliding surfaces (A1, A2) of a fixed end plate (61) and a movable end plate (71). To stabilize the behavior of a movable scroll (70), oil relief passages (83) are provided, which enable the oil inflow grooves (80) formed in the sliding surfaces (A1, A2) of the end plates (61, 71) to communicate with a low-pressure space in a predetermined angular range (α) from a discharge starting point (D1) of the first compression chamber (S21) and a discharge starting point (D1) of the second compression chamber (S22) to the start of discharge of the second compression chamber (S22).
