Claims

[Claims for Utility Model Registration] 1. In a hydraulic latch adjuster that is held within an engine block and transmits the rotational displacement of a cam to intake and exhaust valves without forming a gap; a cup-shaped main body; an oil inlet drilled in the cylindrical portion of the main body for introducing oil from the engineering block; a substantially cylindrical-shaped main body that is coaxially and slidably accommodated in the main body and opens upward; a cup-shaped member; a plunger that is housed in the member in close contact with its outer periphery and in close contact with the main body in the axial direction and guides the member in the axial direction; and a plunger formed between the main body and the member and configured to introduce the oil a supply chamber with an opening; a high pressure chamber formed between the member and the plunger; a supply chamber formed between the plunger and the main body; supplying oil from the supply chamber to the high pressure chamber. an oil passageway communicating between the supply chamber and the supply chamber, comprising: valve means disposed between the supply chamber and the high pressure chamber for supplying and pressing the cup member toward the intake and exhaust valves; A hydraulic lash adjuster, characterized in that the oil inlet is carved on the inner surface of the upper part of the main body so as to open into the supply chamber on the opposite side of the axis with respect to the oil inlet. 2. The hydraulic lash adjuster according to claim 1, wherein the main body is provided with an air vent hole in the cylindrical portion of the main body in the vicinity of the oil inlet just above the oil inlet.
