摘要：
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 said recess mating with that of the said valve; at least one intake and/or exhaust pipe (7, 9) which communicates with the said recess; at least one pipe (10) which connects the said recess with the space inside the cylinder (3) of the reciprocating engine; the said valve has at least one facet (13) or a recess or an eccentric hole which allows communication between the said intake and/or exhaust pipe (7,9) and the said pipe (10) which connects with the space inside the cylinder while the valve itself is rotating, whilst actuating devices are provided which cause the valve to rotate in synchronization with the phases of the reciprocating engine; the actuating devices of the said valve comprise a camshaft (17) to which the said valve is connected so that it can rotate and also slide, the axis of the said shaft coinciding with the axis of revolution of the solid of revolution which forms the valve itself.
