摘要： A compressor includes first and second scroll members and a bearing housing. The first scroll member includes a first end plate and a first scroll wrap. The second scroll member includes a second end plate that has a first surface, a second surface, and an oil passage. The first surface has a second scroll wrap meshingly engaging the first scroll wrap. The second surface includes an oil slot. The oil passage is in fluid communication with the oil slot. The bearing housing cooperates with the second scroll member to define an interior volume. The second scroll member is movable between a first position in which lubricant in the interior volume is allowed to flow into the oil passage via the oil slot, and a second position in which working fluid in the chamber is allowed to flow into the oil passage via the oil slot.
