ROTARY-PISTON OR OSCILLATING-PISTON MACHINES OR ENGINES
F01C
Note(s)
This subclass covers:
rotary-piston or oscillating-piston engines for elastic fluids, e.g. steam;
rotary-piston or oscillating-piston engines for liquids and elastic fluids;
rotary-piston or oscillating-piston machines for elastic fluids;
rotary-piston or oscillating-piston machines for liquids and elastic fluids.
In this subclass, the following expression is used with the meaning indicated:
"rotary-piston machine" includes the German expressions "Drehkolbenmaschinen", "Kreiskolbenmaschinen", and "Umlauf- kolbenmaschinen".
Attention is drawn to the Notes preceding class Fulltext... Hierarchy... Expanded...F01, especially as regards the definitions of "rotary-piston machine", "oscillating-piston machine", "rotary piston", "co-operating members", "movement of co-operating members", "teeth or tooth-equivalents" and "internal-axis".
of arcuate-engagement type, i.e. with circular translatory movement of co-operating members, each member having the same number of teeth or tooth-equivalents
of internal-axis type with equidirectional movement of co-operating members at the points of engagement, or with one of the co-operating members being stationary, the inner member having more teeth or tooth-equivalents than the outer member

·
of counter-engagement type, i.e. the movement of co-operating members at the points of engagement being in opposite directions
