摘要：The invention proposes a variable valve train () for a gas exchange valve () of aninternal combustion engine, which gas exchange valve () is actuated by a cam (), said valvetrain () comprising a force transmission device () that is arranged between the cam () and
the gas exchange valve () and includes a hydraulic lifting device () comprising a pressurepiston () that is arranged for longitudinal displacement in a cylinder (), said pressurepiston () defining a pressure chamber () that is connected to a pressure medium supply ofthe internal combustion engine and said pressure piston () permitting, under high-pressure loading, an actuation of the gas exchange valve () independently of the cam ().The force transmission device () is configured as an oscillating lever or rocker arm ()mounted for pivoting on a lever shaft () comprising a longitudinal channel () thattransports pressure medium and acts as a link () between the pressure medium supplyand the pressure chamber ().
