Abstract

1297848 Rotary-piston I.C. engines DAIMLER-BENZ AG 5 May 1970 [7 May 1969] 21627/70 Heading F1F A radial sealing-strip 1 for the piston of e.g. a trochoidal-type engine, had a curved outer edge, or "head", 9 with a radius 6 substantially greater than half the thickness of the strip. The flexibility of the strip is increased by a slit 2. Bores 4 and/or cut-outs 5 give the working fluid access to the slit and the base 3. In second and third embodiments, Figs.2 and 3, slits 7, 8 or 13, 14 and possibly an additional slit 12 or 17 are provided as shown. In fourth and fifth embodiments, Figs.4 and 5 (not shown), an inwardly tapering slit extends upwardly from the base either obliquely or vertically. The fifth embodiment may also include a slit extending perpendicularly from one of the flanks.
