摘要： A hydraulic valve lifter is held in the recess of the rocker arm swingably pivoted to the rocker shaft. An oil pressure chamber is formed between the lifter body and the plunger. An oil chamber to supply the oil to the oil pressure chamber is formed between the plunger and the recess. An oil supply path to supply the oil through the oil path of the rocker shaft communicates to the oil chamber. A return path is provided extending from the top of the oil chamber to a clearance between the inside of the rocker arm hole and the outside of the rocker shaft or to a clearance between the outside of the lifter body and the inside of the rocker arm recess. With this arrangement of the device, the air infiltrating the oil chamber can be discharged from the top of the oil chamber via the return path and the clearance, thereby preventing invasion of the air into the oil pressure chamber and ensuring normal functioning of the hydraulic valve lifter.

摘要： The present invention provides a variable valve mechanism that varies amounts of opening and closing of a valve includes a rotating cam, a rocker arm, two lash adjusters, a hydraulic passage, and a switching mechanism. The rocker arm includes an input member and an output member. The two lash adjusters support the rocker arm so that the rocker arm can rock. The hydraulic passage includes an internal oil passage that is provided in an interior of at least one of the lash adjusters, and an arm oil passage that is provided in an interior of the rocker arm and that is connected from the internal oil passage. The switching mechanism uses a hydraulic pressure in the hydraulic passage to perform a switching between a linked state and a released state, and the switching varies the amounts of the opening and the closing of the valve.
