    摘要： A cylinder head assembly is for an internal combustion engine. The cylinder head assembly includes a cylinder head and first and second valves coupled to the cylinder head. The first and second valves are associated with a combustion chamber partially defined by the cylinder head. The cylinder head assembly also includes a fixed member coupled to the cylinder head and a valve bridge engageable with the first and second valves. The valve bridge is axially moveable along an axis relative to the fixed member to move the first and second valves together between an open position and a closed position. The cylinder head assembly further includes an anti-rotation feature between the valve bridge and the fixed member. The anti-rotation feature restricts rotational movement of the valve bridge about the axis.

    摘要： A hydraulic flow adjuster includes a first hydraulic tank, a second hydraulic tank, and a piston actuator. A first piston operates within the first hydraulic tank and a second piston operates within the second hydraulic tank. The piston actuator adjusts a relative position of the first piston in the first hydraulic tank and a relative position of the second piston position in the second hydraulic tank, such that the relative position of the first piston in the first hydraulic tank is the same as the relative position of the second piston in the second hydraulic tank.
