Abstract
A system and apparatus for compressing gaseous fluids, especially refrigerant gas vapors operating in refrigeration cycles, combining reciprocating pistons in a rotating cylinder member which is mounted for rotation in a stationary frame and is driven by an external source of rotative power. The cylinder block rotates in an encircling port ring member which contains inlet, interstage, and outlet port sets with the number of port sets, numbering more or less than the number of cylinders, to provide a vernier effect in the timing of connections between the port sets and the cylinders.
