  • Patent number: 5722361
    Abstract: An internal combustion engine with rotating pistons works on the basis of the cat and mouse principle. The charge is axially exchanged over one of the housing lids (28) and the adjacent rotary side disk (24). The combustion chambers (34) are formed by axially open recesses in the pistons (24) of the outer rotor (12) which communicate transversely to the axial direction with the adjacent working chambers (20). The fuel is supplied by injection nozzles (30) oriented in the corresponding housing lid (28) in the direction of the rotary side disk (24).

  • Patent number: 4957068
    Abstract: A liquid-cooled, four-valve cylinder head for a multi-cylinder internal-combustion engine comprises a casting having a cooling-fluid space between the cylinder-head bottom and a cylinder-head cover in which supporting struts are arranged for reinforcing the cylinder-head bottom, valve channels of gas-reversing valves and chambers for receiving secondary combustion spaces. Above the cooling-fluid space is located a control space with guide housings for receiving the cup tappets for the actuation of the gas-reversing valves. In order to obtain a cylinder-head construction which is structurally rigid and nevertheless can easily be produced, the chambers are cast together with the valve channels within the cooling-fluid space. Further, the supporting struts are equipped with ribs projecting into adjacent combustion-space portions, and the lateral outer walls of the cylinder-head housing are connected to one another in the region of the control space by transverse booms.

  • Patent number: 4284042
    Abstract: A multicylinder internal combustion engine with valve disconnection wherein an intermediate mechanical device is interposed between an end of the valve stem end and a valve actuating mechanism with the intermediate mechanical device arbitrarily serving, in one case, as a rigid intermediate member between the end of the valve stem and the valve actuating mechanism and, in another case, in a closed setting of the valve, abolishes or eliminates the interconnection between the end of the valve stem and the valve actuating means.

  • Patent number: 4267811
    Abstract: A cylinder head for a mixture-compressing internal combustion engine with relatively small cylinder diameter, with a V-arrangement of two inlet valves and two exhaust valves each, which are actuated from a centrally arranged cam shaft by way of rocker arms; each rocker arm provided for the actuation of an inlet valve or each rocker arm provided for the actuation of an exhaust valve is supported overhung or all rocker arms are supported centrally while the spark plug is so arranged that the center longitudinal axis through the spark plug extends approximately parallel to the inlet valves or exhaust valves between the same and the cam shaft.
