Distributor for reciprocating heat engine

摘要

There is a shaft on the engine cylinder head with two distributor discs (5) for each cylinder. Each cylinder contains a groove along its angular sector. Thus, in one position the grooves close one of two coupled lines, while opening the other one, and providing a reversed action in the other position for intake and exhaust engine strokes. Each distributor disc contains a lightly cylindrical inner zone (5c), extending up to the lightly frusto-conical walls (5a,b) of the disc, fitted with sealing elements.
