Abstract
A two-way flow rotary valve for a reversible compressor is disclosed. The two-way flow rotary valve comprises a tubular member with a first end and a second end. Two or more low friction face seals are disposed around the tubular member between the first end and the second end and a central section is disposed between the two or more low friction face seals. The two or more low friction face seals allow the central section to rotate within a substantially cylindrical receiver of a cylinder head. A gas port extends through the tubular member and is configured to allow the rotary valve to selectively exchange gas with a cylinder (when used as a compressor and when used as an air motor).
