Pressurized vapor driven rotary engine
This patent describes a pressurized fluid rotary engine. It comprises a piston housing; first and second hubs, each hub being rotatably supported in the piston housing about a common axis; piston heads extending radially outwardly from the hubs for travel in a circular path about the axis, each piston head having a pair of working surfaces, each working surface facing the piston head adjacent thereto; a transmission housing coupled to the piston housing; an output shaft extending from the transmission housing; a pair of crank levers each coupled to one of the hubs and rotatably mounted about the axis; a pair of connecting rods each having first and second portions, each first end portion being pivotally coupled to nose of the crank levers; a sun gear secured to the transmission housing; a pair of planet gears coupled to the sun gear; a pair of crank journals; a pair of crankshafts each having a first portion pivotally coupled through one of the crank journals to the second end portion of one of the connecting rods and a second portion coupled to one of the planet gears and the output shaft for rotating the plate gears and the output shaft; and the moment arm between the axis and each connecting rod.
