ABSTRACT:
A rotary piston engine has a plurality of sealing elements, each of which includes a cylindrical stationary bearing portion pressed into the rotor and at least one curved blade extending therefrom. The curved blade engages the race of the stator and is adapted to pivot into a curved recess in the rotor. The sealing elements may have a second curved blade extending from the stationary bearing portion oppositely from the first blade. The underneath side of the blades nearest the stator may have longitudinal grooves provided therein to facilitate their lifting from the stator surface. The sealing elements may be made from plastic or may be a two piece construction of plastic and metal.
