Abstract: The disclosure teaches a novel radial engine. In accordance with the teachings of the disclosure, the radial engine includes a housing and a plurality of equally spaced openings disposed in a ring-like arrangement on the periphery of the housing. A respective piston and cylinder arrangement is located in each opening, and the piston rod of each piston and cylinder arrangement extends inwardly from its respective piston through its respective opening. A shoe means is pivotally attached at the other end of each piston rod, and a connecting ring is mounted for circular translation motion on the crankshaft within the housing. A respective channel or guides extend radially inward in the housing in line with each piston rod to permit radially inward motion of the shoe means and to guide the connecting rod block in this motion. Each shoe means is guidably connected to the peripheral edge of the connecting ring.
