Patent ID: 7762223

Claim:
A valve train of an internal combustion engine, said valve train comprising a stationery support element that is mounted in the internal combustion engine and further comprising a finger lever or a rocker arm for a stroke-operation of a gas exchange valve between a closed position and an open position, said finger lever or rocket arm comprising a joint socket comprising a semispherical portion for a pivotal mounting of the finger lever or rocker arm on a spherical joint head of the support element and further comprising, adjacent to the semispherical portion, a depression from which a spray bore starts to extend through the joint socket for transporting hydraulic medium to a contact surface of the finger lever or rocker arm for contact with a valve train component that drives the finger lever or rocker arm, said spray bore being in hydraulic communication with a supply bore that, downstream of a hydraulic medium supply connected to the support element, extends through the spherical joint head and opens within the joint socket, wherein a valve body that is arranged in the depression for displacement with an outer peripheral surface on an inner peripheral surface of the depression and is biased by gravitational force and/or by a force of a spring means towards the spherical joint head and comprises a projection cooperation with the supply bore, so that, in the closed position of the gas exchange valve, the spray bore and the supply bore are substantially or entirely separated hydraulically from each other by a snapping of the projection into the supply bore.
