摘要：Oil retention recesses are formed on either or both orbiting and non-orbitingscroll elements. In one embodiment, the recesses are formed in a tip of a wrap of at leastone of the scroll members. In another embodiment the recesses are formed on the base
of at least one of the scroll elements. The recesses ensure that a sufficient quantity of oilis captured within the recesses to provide the lubrication into the interfacing surface ofthese elements. The recesses help, after a compressor is shutdown for long periods, toprovide as lack of lubricant between the engaged scroll elements upon compressor startup. Other events may also cause momentary loss of oil supply at the compressor, suchas, for example, compressor flooding. The recesses also help during intermittentinterruption of oil delivery or when the amount of oil circulation is less than desirable.
