Abstract
An orbital engine has a piston member journalled on a shaft within a housing to orbit therein upon rotation of the shaft. A plurality of vanes form with the housing and piston member a plurality of variable volume chambers. An annular sealing member is mounted in a recess in a radial face of the piston member and engages an opposed radial face of the housing to form a seal therebetween. The sealing member has a radial face engaging the radial face of the housing and a non-radial face engaging a wall of the recess in the piston and a resilient member urging the radial and non-radial faces of the sealing member into sealing engagement with the housing and piston member.
