Abstract

1350728 Rotary positive-displacement machines DORNIER SYSTEM GmbH 15 June 1972 28037/72 Heading F1F To facilitate radial sealing in a trochoidaltype machine, which may be an I. C. engine, pump or steam engine, with a 1:2 configuration the piston and casing profiles K, G are at uniform radial distances a K , a G from a true 1:1 epitrochoid T 1 and its outer envelope curve Ha. The distance a K is greater than distance a G so as to provide a gap of width A permitting an adequate radius for the semi-cylindrical tip of each sealing strip D, the tip radius being a K . The axis of curvature of the tip contains a point S common to the epitrochoid and the curve Ha. Generally similar provisions are made in embodiments based on a 2:1 epitrochoid and its inner envelope curve, a 6:1 hypotrochoid and its inner envelope curve, and a 3:1 hypotrochoid and its outer envelope curve, Figs.2-4a (not shown).
