F03C2/00 - CPC Classification

Classification description:

Rotary-piston engines

Sub-classes:

F03C2/02 » 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 7
F03C2/08 » of intermeshing-engagement type, i.e. with engagement of co- operating members similar to that of toothed gearing 93
F03C2/22 » 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 3
F03C2/24 » of counter-engagement type, i.e. the movement of co-operating members at the points of engagement being in opposite directions 0
F03C2/30 » having the characteristics covered by two or more of groups , , , or having the characteristics covered by one of these groups together with some other type of movement between co-operating members 5
