    • 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.
    • 旋转活塞发动机具有多个密封元件,每个密封元件包括压入转子的圆柱形固定轴承部分和从其延伸的至少一个弯曲刀片。 弯曲的叶片接合定子的座圈并且适于枢转到转子中的弯曲凹槽中。 密封元件可以具有从固定轴承部分与第一叶片相对地延伸的第二弯曲刀片。 最靠近定子的叶片的下侧可以具有设置在其中的纵向槽,以便于它们从定子表面提升。 密封元件可以由塑料制成,或者可以是塑料和金属的两件式结构。
