Description

Class  F01C : ROTARY-PISTON OR OSCILLATING-PISTON MACHINES OR ENGINES


Subclass 1/20: Rotary-piston machines or engines (with axes of co-operating members non-parallel F01C 3/00; with the working-chamber walls at least partly resiliently deformable F01C 5/00; with fluid ring or the like F01C 7/00; rotary-piston machines or engines in which the working fluid is exclusively displaced by, or exclusively displaces, one or more reciprocating pistons F01B 13/00) of intermeshing-engagement type, i.e. with engagement of co-operating members similar to that of toothed gearing of other than internal-axis type with toothed rotary pistons with dissimilar tooth forms (F01C 1/16 takes precedence)
