    摘要: A hollow poppet valve (31) is disclosed, in which a stem portion (13) includes a flared fillet portion (17), having a wall thickness (T), and a downwardly-extending cylindrical portion (33;51), having a cylindrical external surface (35). In the main embodiment, the valve includes a cap member (15) defining a seat face (25), and a cylindrical internal surface (39), the internal and external surfaces (39,35) being closely spaced apart, defining an interface having an axial length (L), and being consumed by a weld (43). Preferably, the length (L) of the weld (43) is equal to at least 1.1 times the thickness (T). The fillet portion (17) defines an internal fillet radius (R1), greater than 0.3 times the thickness (T), and near the radius (R1) is a transition region (TR). The present invention improves fatigue strength of the poppet valve by separating the transition region (TR) from the weld (43) so that there is overlap for no more than a minor portion of the weld.

    摘要: A rocker arm for engaging a cam is disclosed. An outer arm and inner arm are configured to transfer motion to a valve of an internal combustion engine. A latching mechanism includes a latch, sleeve and orientation member. The sleeve engages the latch and a bore in the inner arm, and also provides an opening for an orientation member used in providing the correct orientation for the latch with respect to the sleeve and the inner arm. The sleeve, latch and inner arm have reference marks used to determine the optimal orientation for the latch.
