Summary:

On internal combustion engines, the intake and exhaust valves are reciprocated by the cam mechanism. Cam-shower' is oil supplying device for each cam of a camshaft.The conventional cam-shower is simple pipe shape with several same size outlets for each cam. Oil from cylinder head is supplied in the middle point of cam-shower pipe. The oil flow of outlets near the oil supplied point is large amount, and outlet far from supplied point is small. The distribution of oil flow from each outlet is uneven.A new structure of cam-shower has been developed, and it has two important features. First, it has branched oil passage like cereoid cactus. Second, supplied oil flow from cylinder head to a cam-shower is intermittent by using throughhole passage in a camshaft journal.The new developed cam-shower properly distributes oil flow to each cam evenly and reduces wasted oil flow, so that total amount of oil flow of the cam-shower can be remarkably reduced by 90%. Then small discharge rate of the oil pump for engine can be set up and its driving torque gets lower. Eventually, that achieves low fuel consumption of engine
