发明名称 Device for sealing between the rotary piston and the separating slide of a rotary engine, a rotary piston pump, or the like
摘要 A sealing arrangement in a rotary machine between the eccentric rotary piston and the separating slide engaging a recess in the piston. A spring-loaded strip is guided in a lengthwise slot of the rotary piston, and is in contact with each side wall of the separating slide throughout the entire length. The vertex formed by an obtuse angle of the front sides of the strip in the region of the center line of the strip, is in sliding-motion connection with the side wall of the separating slide. The center line of the strip forms an angle of substantially 55 DEG with the center line of the separating slide, at dead center. Compression springs associated with the rear side of the strip are held in blind holes which are spaced by a predetermined distance. The recess of the rotary piston which accommodates the separating slide, has a trapezoidal cross-section. Facing lengthwise slots for the strips are located in the upper region of the recess of the rotary piston, and the separating slide and strips are made of materials of different hardness.
