ABSTRACT In my invention of a rotary engine the displacement is accomplished with ordinary pistons and cylinders, and by this means the problems of blow-by and oil- drift in lobe-type and sliding vane type rotary engines are avoided. In my engine two sets of pistons are opposed and they are adapted to reciprocate in two opposed groups of cylinder chambers spaced around the circumference of two rotary members all parallel to the axis of rotation. The two circular groups of cylinders are rotated on an angle with respect to each other, and the angle acts to make the fixed piston sets reciprocate within the cylinders. The main advantage of this arrangement is that the usual valve-shafts, crank-shafts, connecting rods and the related bearings are all eliminated. The four stroke cycle is accomplished during one revolution of the engine by using a high-pressure fuel injection jet between two sets of pistons, and the valve action is accomplished by using cones with ports at suitable intervals. Two rows of cylinders can be used around the circumference of each rotating member with one row performing as intake stroke and compression stroke and the other row performing as the work stroke and the exhaust stroke.
