• F01C 1/02 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
• F01C 1/08 of intermeshing-engagement type, i.e. with engagement of co-operating members similar to that of toothed gearing
• F01C 1/22 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
• F01C 1/24 of counter-engagement type, i.e. the movement of co-operating members at the points of engagement being in opposite directions
• F01C 1/3 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
