Device for increasing the transmission of inlet and exhaust port in reciprocating piston internal combustion engines

摘要

In a device for increasing the transmission of the inlet and exhaust port in reciprocating piston internal combustion engines with a cylinder, having a combustion chamber, and a cylinder head which has the inlet port and the exhaust port, which open out into a common port connecting with the combustion chamber and can be controlled by valves, the increase of the transmission can be reliably achieved in that a poppet valve (8) is arranged between the ends of inlet port (3) and exhaust port (4) facing the common port (5), which valve has valve seat surfaces (8' and 8'') on both sides and can be alternately applied with the valve seat surfaces (8', 8'') to valve seat surfaces (3', 4') of the inlet port (3) or exhaust port (4), and the common port (5) of which can be closed or opened by a further valve (7). <IMAGE>
