Abstract

See full text

A rotary device includes a housing having a tubular surface. The surface has an throughpassing axis and first and second ports. A rotor body rotates about the axis and has a plurality of slots extending generally radially from the axis. A vane is mounted in each slot for reciprocation such that the surface can be swept by the vanes as the body rotates. A seal permits fluid to flow into and out of the device substantially only via the first and second ports such that the vanes create chambers which decrease in volume when in communication with the first port and increase in volume when in communication with the second port. The tubular surface is oval in cross-section.
