能なバルブロツカアーム。 A cylinder hole is provided at either end of the valve rocker arm body, which opens and closes the intake or exhaust valve of a V-type or horizontally opposed internal combustion engine by the rotation of the cam, and the cam or valve is installed inside this cylinder hole. A plunger having a sliding surface that comes into sliding contact with either side is slidably inserted in the axial direction, and a seat plunger is fitted inside the plunger so as to define the interior of the plunger into a reservoir chamber and a high pressure chamber. A check valve is provided in the communication hole formed in the seat plunger to allow compensation flow of oil from the reservoir chamber to the high pressure chamber, and a check valve is installed in the high pressure chamber to separate the plunger and the seat plunger from each other. A latch characterized in that a biasing return spring is provided, an air separation passage is formed between the cylinder hole and the plunger, and an air vent hole that communicates with the atmosphere is provided only in the vertically upper part of the air separation passage. Adjustable valve brodka arm.
