ABSTRACT:
A rotary compressor is provided, including: a housing containing a rotor having a compression eccentric and an axial shaft; a removable combination intake and exhaust manifold for conveying fluid into and out of a compression space formed between the compressor housing, the compression eccentric, and a removable combination dynamic seal and fluid channeling assembly which is securable between the manifold and the housing. The combination dynamic seal and fluid channeling assembly retains a dynamic seal in continuous contact with the compression eccentric and directs fluid into and out of the compression space. After being introduced through an intake port of the manifold, fluid is transferred past the combination dynamic seal and fluid channeling assembly, through a seal-engaging channel in the housing and into the compression space, where it is compressed via rotation of the compression eccentric about the axial shaft. Compressed fluid exits the compression space back through the seal-engaging channel and is directed toward an exhaust port of the manifold via the combination dynamic seal and fluid channeling assembly.
