Abstract
A valve-actuating lever for reciprocating-piston internal combustion engines is proposed, wherein this lever is supported on a cylinder head of the internal combustion engine or a part of this cylinder head, is in active connection with a cam of a camshaft, has an essentially inverted U-shaped cross section, is made from steel sheet metal by a punching, bending, and/or deep-drawing measure, and has, in addition to a support plate (5) for a shaft of a gas-exchange valve or for an intermediate piece, lateral guide cheeks (3, 4). A height of the lateral guide cheeks (3, 4) can be changed with regard to the support plate (5) by an embossing procedure.
Claims4
A valve-actuating lever for reciprocating-piston internal combustion engines, wherein the valve-actuating lever is supported on a cylinder head of the internal combustion engine or a part of the cylinder head and contacts a cam of a camshaft, the valve-actuating lever comprising an essentially inverted U-shaped cross section formed from steel sheet metal that is at least one of punched, bent, or deep-drawn, and includes a support plate defining a support surface for a shaft of a gas-exchange valve or an intermediate piece, and lateral guide cheeks, and a height of the lateral guide cheeks with respect to the support plate is changed by embossing an opposite side of the support plate such that a top surface of the support plate opposite the support surface is indented relative to the lateral guide cheeks.
