ROTARY-PISTON OR OSCILLATING-PISTON MACHINES OR ENGINES
F01C
Note(s)
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", and "internal-axis".
The subject-matter of this sub-class comprises:
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 liquids and elastic fluids.
In this sub-class, the term "rotary-piston machine" embraces the German terms "Drehkolbenmaschinen", "Kreiskolbenmaschinen", and "Umlaufkolbenmaschinen".
of internal-axis type with equidirectional movement of co-operating members at the points of interengagement the inner member having more teeth or tooth-equivalents than the outer member
F01C 1/24
·
of counter-engagement type, i.e. the movement of co-operating members at the points of interengagement being in opposite directions
with coaxially-mounted members have continuously-changing circumferential distance
F01C 3/00
