Rotary piston engine
US 6868822 B1

Angelo Di Pietro 1999

A non-reciprocating engine comprising a hollow cylindrical shaft driver (13) located in a cylindrical stator cavity (14) of a stator. A number of expansion chambers (43) form between the outer wall of the shaft driver, the stator wall and movable dividers (25) which extend from the stator to bear on the shaft driver. The expansion chambers expand and contract during operation of the engine. An output shaft passes centrally through the stator cavity and shaft driver and has offset bearings (34) which bear on the inside surface of the shaft driver. Inlet ports in a removable inlet end plate of the stator allow pressurised air or air/fuel mixture, for example, to be introduced into the expansion chambers. Sequential expansion and contraction of the chambers around the circumference of the shaft driver causes a combination of orbital and rotational movement of the shaft driver and consequential rotation of the output shaft. The shaft driver rotates at only a fraction of the speed of rotation of the output shaft (in the order of

Klaus Herrmann 2005
Rotary piston engine (33) has two rotators (2,2a), in which 9-12 double actingrotary pistons (1,1a) are supported by fulcrum pins (3). The rotators form a hollow-shaped cylinder space with the housing (22) and a second gas-tight working chamber (4) in the two rotators for the rotary piston. The rotor rotates with theengine shaft (14) to the right, the rotor rotates with the engine shaft (14a) to the left and in such a way forms a flow direction for the working medium. By the displacement of the engine shafts, the rotators form working and pressure chambers (10) and the expansion chamber (20) with the rotary pistons. The upperpiston working surface forms a tangent to the rotators. Additionally the double acting rotary pistons are suspended by a stopper (7) and strengthen with a heat-proof material plate (5,6).

A rotary piston internal combustion engine with two counter-rotating pistons (14, 15) located on the same axis and engaging with one another. One of the pistons acts as a compression or charging piston and the other as an expansion or propulsion piston. The design is aimed at providing a favourable co-ordination between the charging piston and the propulsion piston with the operating chamber of the propulsion piston being several times that of the charging piston, and is such that the two rotary pistons, whilst maintaining conjugate peripheral angles of approximately 360o, possess different peripheral lengths which leave in the rotarypiston paths
