Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
124 words
In a disk valve structure in an internal combustion cam engine, said valve having an axis of rotation and disposed within a housing for feeding and exhausting fuel mixtures, said housing having on each side thereof a pair of cylinder blocks with each block having a pair of cylinders disposed on opposite sides of said axis of rotation, the improvement comprising: each of said cylinder blocks having at least one carbureting source adjacent each cylinder thereof, said disk valve being configured to conduct fuel mixture to each cylinder of each pair of blocks from said carbureting source disposed on the opposite cylinder of said respective block, whereby fuel mixture may absorb heat from said disk valve during an intake stroke of each individual cylinder.
