Abstract: An air motor assembly includes an exhaust block with an exhaust port that conveys exhaust air into an exhaust manifold. The exhaust port includes an expansion chamber that creates a pressure drop in the exhaust gas, thereby decreasing the temperature of the exhaust gas. The expansion chamber is defined between a first wall that is tangential to the air motor cylinder and a second wall that is transverse to an axis of the exhaust port. Poppet valves control actuation of a shuttle. The poppet valves are disposed on the exterior of the air motor assembly and are thermally insulated from the air motor assembly.
