Title: Assembling arrangement for tensioner and hydraulic control valve

Abstract: A tensioner for a camshaft driving chain (a plunger device 17 shown in thefirst embodiment of the invention) and a hydraulic control valve 21 aredisposed close to each other. An oil passage 31 for supplying an oilpressure to the tensioner is caused to branch off from a downstream sideof an oil filter 27 provided at an inlet port 28 of the hydraulic controlvalve. With this construction, the arrangement of the oil passage can besimplified, and therefore not only can man hours required for forming theoil passage be reduced, but also the number of components required canalso be reduced by commonizing the oil filter. Accordingly, it is possibleto provide an improved assembling arrangement for a tensioner and ahydraulic control valve in an internal combustion engine without involvingan increase in production costs.
