Rotary piston engine with reciprocating cylinders having sealing and friction reducing members
A rotary engine is described comprising, in combination, a non-rotatable housing having a central axis, a first member rotatably mounted in the housing for rotation about the central axis and having its axis of rotation coaxial with the axis of the housing, a first and a second pair of pistons with the pistons of each pair of pistons being diametrically opposed to and coaxial with each other, the pairs of pistons being rigidly secured to the first member adjacent the external periphery thereof and projecting radially inward therefrom, a power shaft rotatably mounted in the housing and having a shaft portion thereof extending from the housing and a square cam portion thereof disposed within the housing centrally of and spaced from the pistons, the shaft being eccentrically mounted with respect to the housing and the first member, the square cam having four flat surfaces thereon with each of the surfaces having one of the pistons disposed perpendicularly relative thereto and, as a result of the eccentric mounting of the shaft, the shaft rotating eccentrically relative to the pistons and the first chamber, a cylinder sealingly and telescopically received on each of the pistons with the radially inner end of each cylinder sealingly and slideably engaging a different one of the flat surfaces of the square cam and being disposed constantly perpendicular to such engaged flat surface, the cylinders being disposed in two pairs with the cylinders of each pair being opposed and coaxial, two pairs of bridle rings, with each pair of bridle rings connecting one opposed pair of cylinders and the bridle rings insuring that opposed cylinders move conjointly and that their inner ends sealingly engage the square cam.
