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 extending around surfaces of the rotor and together defining closed working chambers in a housing in which the rotor is rotatable, adjacent ends of the seals being connected together by connectors, often called bolts, located in sockets in the rotor. Each bolt has clearance laterally of its longitudinal axis from the peripheral wall of the socket to permit lateral movement of the bolt in the socket except in one direction laterally of the longitudinal axis of the bolt, in which direction, movement of the bolt is restrained by the bolt being held between fixed laterally opposite positions engaging its peripheral surface.
