ABSTRACT:
A rotary piston machine of the type having a slant or precessing rotor or the type having a parallel axis rotor, such as a Wankel engine, having a rotor seal grid formed from peripheral and apex seals which are connected together at their adjacent ends by connectors, often called bolts, located in sockets in the rotor. An arcuate seal extends peripherally around each bolt in the manner of a piston ring between the peripheral surface of the bolt and the adjacent peripheral wall of the socket in which the bolt is located, to effect sealing between the peripheral walls of the bolt and the socket without inhibiting relative movement of the bolt in the socket.
