Abstract
A rotary piston engine with a frame, a cylinder liner mounted rotatably therein, a rotor mounted coaxially in the cylinder liner and a gear mechanism connecting the frame, the liner and the rotor, where the gear mechanism is outside a working space arranged between liner and rotor and where the gear mechanism couples the cylinder liner and the rotor for a relative movement periodically oscillating between positive and negative rotational speed. The gear mechanism and the liner form with the rotor a transmission with five rotational joints with a degree of freedom of one and one rotational/prismatic joint, where the gear mechanism has a rotational element mounted rotatably by a first rotational joint on the frame and a connecting rod connected rotatably by a second rotational joint to the rotational element and rotatably by a third rotational joint to the cylinder liner and by the rotational/prismatic joint to the rotor.
