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