Abstract
A radial seal for a rotary piston internal combustion engine, especially of trochoidal construction, which is constituted by a sealing bar, possibly of multi-partite construction, that is guided in an axially parallel groove of a piston and is forced radially outwardly by springs; the springs are thereby arranged separate from one another in series one behind the other--as viewed in the longitudinal direction of the groove.
