Abstract
Shown is a latch pin for use in a valve lifter and a valve lifter including the same. The latch pin for selectively latching within a pin chamber provided in the valve lifter is configured as a whole as a cylindrical pin with one end in the shape of a spherical crown, wherein a stepped flat is formed on radially one side of said one end and is dimensioned to be received within the pin chamber to engage with an axial latching surface thereof. On the top side of said one end, a first relief is formed by beveling the spherical crown, and on the radially other side opposite to the stepped flat across said first relief, a second relief is formed by beveling the spherical crown, wherein the second relief radially adjoins the first relief and circumferentially adjoins a remaining pin face in the shape of the spherical crown.
