バルブリフター。[Scope of Claim for Utility Model Registration] A hydraulic valve lifter that is held within a cylinder head and transmits the rotational displacement of a cam to intake and exhaust valves without creating a valve clearance, which is substantially cylindrical in shape and has a cylindrical portion that opens downward. a cup-shaped follower; a substantially cylindrical body that is coaxially and slidably housed in the follower and opens upward; and a cup-shaped follower that is housed in the body in close contact with the outer periphery and in close contact with the follower in the axial direction; a plunger that guides the body in the axial direction; a plunger defined between the follower and the plunger;
a reservoir to which oil is replenished from the supply chamber; a high-pressure chamber defined between the body and the plunger; and a high-pressure chamber that supplies oil from the reservoir to the high-pressure chamber and connects the body to the intake and exhaust valves. a valve means provided between the reservoir and the high pressure chamber for pressing; an oil inlet drilled in the cylindrical portion of the follower for introducing oil from the engine block into the supply chamber; A hydraulic valve lifter comprising: the follower integrally having a portion for holding the body.
