ABSTRACT:
The invention relates to a rotary type piston machine of the type having inner and outer relatively rotatable and orbital ring and wheel gears and a pivotal drive shaft connected to the wheel gear. The casing forms sidewalls for the gears and leakage between the wheel gear and the sidewalls is a chronic problem. The wheel gear on the side opposite from the drive shaft is provided with an annular groove and a sealing ring therein to provide sealing between the inner gear element and the adjacent sidewall. The shaft side of the wheel gear has recessed areas in the crests of the teeth thereof to provide pressure compensation for the effect of the sealing the above referred to sealing ring on the opposite side thereof.
