Title:
VARIABLE-DISPLACEMENT COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2011/162072
Kind Code:
A1
Abstract:
Disclosed is a variable-displacement compressor for which lubrication performance and durability are ensured. The following are formed through a peripheral wall of a front housing (101): a first connection hole (202) adjacent to the upstream side, in a rotation direction, of a through bolt (201a) disposed outside a rotation track for a rotating member such as a swash plate inside a front housing (101); and a second connection hole adjacent to the downstream side, in the rotation direction, of an upper through bolt (201b). A storage chamber (206) that stores an oil in a refrigerant is provided outside the front housing (101) and connected, via the first and second connection holes, to the space inside the front housing (101). In-refrigerant oil caught on the upstream side of the first through bolt (201a) enters the storage chamber (206) via the first connection hole (202) as the refrigerant from the storage chamber (206) is returned to the space inside the front housing (101) via the second connection hole (203), such that the amount stored increases as the speed of rotation increases.
