A valve train 10 comprising at least one valve 12, at least one plunger 16 slidable in a corresponding cylinder 14, at least one rocker arm 18 coupling the valve and the plunger, a first chamber 48 bounded at least partially by the cylinder and the plunger and being capable of receiving a fluid, for example a hydraulic fluid, a second chamber 50 bounded at least partially by the cylinder and the plunger, the first chamber being arranged on a first side 52 of the plunger and the second chamber being arranged on a second side 54, at least one duct 56 fluidically connecting the two chambers, and at least one valve SV, for example a solenoid valve, for adjusting the flow of the fluid from one of the chambers through the duct to the other chamber thereby adjusting a valve lift of the valve. The assembly allows for precise adjustments of the valve stroke leading to increased efficiency and power of the associated engine. |
