特徴とするバルブリフタ組立体。a cup-shaped first plunger element having a plunger bore formed in a cylinder head and an upwardly open cylinder bore slidably received within the plunger bore;
a hollow box-shaped second plunger element that is slidably received in the cylinder head of the plunger element and that is constructed by joining members and has an inner chamber therein; A cylinder chamber whose upper end is limited by the lower end wall of the second plunger element is formed in the plunger element, and the lower end wall of the second plunger element connects the inner chamber and the cylinder chamber. A hole is formed in the hole □, and a check valve is installed in the hole □ to allow fluid to flow only from the inner chamber toward the cylinder chamber. A compression coil spring is provided which acts in a direction of pushing out from the first plunger element;
and a second plunger element has a through hole in its cylindrical side wall that is in constant communication with each other, and the through hole of the second plunger element is in constant communication with an oil passage formed in the cylinder head and opening into the plunger bore. The upper end wall of the second plunger element is configured to directly contact and engage the valve lift cam, and the lower end wall of the first plunger element is configured to exert a valve opening pushing force on the valve stem. Features a valve lifter assembly.
