  • Timing device for reciprocating positive-displacement engines, such as endothermic reciprocating engines, with a rotary valve in the shape of a solid of revolution particularly a sphere
    Patent number: 4834038
    Abstract: For each cylinder a timing device comprises at least one valve (12) in the shape of a solid of revolution which rotates inside a corresponding recess (15) in a seat formed in the cylinder head (1), the surface of the recess mating with that of the valve; at least one intake and/or exhaust pipe (7, 9) which communicates with the recess; at least one pipe (10) which connects the recess with the space inside the cylinder (3) of the reciprocating engine. The valve has at least one facet (13) or a recess or an eccentric hole which allows communication between the intake and/or exhaust pipe (7,9) and the pipe (10) which connects with the space inside the cylinder while the valve itself is rotating. Actuating devices are provided which cause the valve to rotate in synchronization with the phases of the reciprocating engine.
