Abstract
A swashplate-type compressor is provided. The compressor has a housing member that defines a plurality of grooves having features that allow the grooves to direct lubricating oil splashed against the housing member toward a central opening that houses a bearing and shaft. Preferably, the grooves comprise an annular groove and a series of oil collection grooves emanating outward from the annular groove. Each oil collection groove has a first wall that is substantially perpendicular to the plane of the housing member and a second wall that is angled with respect to both the first wall and the plane of the housing member. Also, each oil collection groove is in fluid communication with the annular groove. The housing member may further define one or more axial holes disposed within the annular groove.
