Claims

[Scope of Claim for Utility Model Registration] (1) A disk-shaped shim of uniform thickness is provided on the top seat surface of the intake and exhaust valve that slides over the shaft end of the intake and exhaust valve of an internal combustion engine and comes into contact with the intake and exhaust valve. What is claimed is: 1. A valve lifter installed in the valve lifter, characterized in that a communication passage is provided that communicates a press-fitting part formed to be open to the outside and a discharge part formed on a mounting surface side of the shim. (2) The valve lifter according to claim 1, wherein the communication passage is a small hole bored in the top portion. (3) The valve lifter according to claim 1 or 2, wherein the press-fit portion is opened in a sliding surface of the valve lifter. (4) The valve lifter according to any one of claims 1 to 3, wherein the discharge part is formed near the center of the seat surface of the top part. (5) The valve lifter according to any one of claims 1 to 4, wherein the discharge portion has a concave shape with a concave seating surface at the top. (6) The valve lifter according to any one of claims 1, 2, 4, and 5, wherein the press-fitting portion is opened at an end face of the valve lifter. (7) The valve lifter according to any one of claims 1, 4, and 5, wherein the communicating path is a groove dug in the seat surface of the top portion. (8) Utility model registration claims 1, 4, 5, and 7, characterized in that the press-fitting part is opened at the inner circumferential surface of the top part that contacts the outer circumferential surface of the shim. The valve lifter described in any of the paragraphs. (9) The valve lifter according to claim 1, wherein the communication path is a groove dug in the mounting surface of the shim. (10) The valve lifter according to claim 1 or 9, wherein the press-fit portion is opened toward the outer peripheral surface of the shim. (11) 11 Utility model registration claims 1, 9, and 1, characterized in that the discharge portion has a concave shape in which the mounting surface of the shim is depressed near the center.
The valve lifter according to any one of item 0.
