WIPO Patent Application WO/2017/217523
Kind Code:
A1
Abstract:
[Problem] To provide a compressor that is capable of preventing an oil supply passage from being clogged even when there is a foreign object in the structure in which lubricating oil, stored in an oil storage chamber located in a high-pressure region, is supplied through the oil supply passage that is provided with an orifice to the portion of relatively low pressure. [Solution] A rear head (3) is provided with an oil supply passage (45) that connects an oil storage chamber (38) and a back-pressure recess (46). A filter assembly (50) in which a strainer (51) and an orifice (54) are integrally formed is provided midway of the oil supply passage (45). The oil supply passage (45) is configured by arranging a first oil supply hole (45a) bored from a first direction and a second oil supply hole (45b) bored from a second direction so as to intersect each other inside the rear head (3).
