Valve arrangement and valve guide

A valve arrangement for supplying air to an internal combustion engine, the valve arrangement comprising:

• a first valve for controlling an air supply to a cylinder, the first valve being movable between a closed position in which the air cannot be supplied to the cylinder and an open position in which the air is supplied to the cylinder, the first valve comprising:
• a first valve head, and a first valve stem comprising an inlet in a side wall of the first valve stem, wherein the inlet is configured to receive additional air from a feeder channel, the first valve stem further comprising an internal passage, arranged in the length direction of the valve stem and fluidly connected to the inlet and configured to supply the additional air to the cylinder;
• a second valve arranged within the first valve and configured to control the flow of additional air to the cylinder, the second valve comprising a second valve stem and a second valve head in contact with an inner surface of the first valve head when the second valve is in a closed position;
• a tubular valve guide arranged to surround a portion of the first valve stem such that the first valve stem is movable in the valve guide;
• wherein the valve guide comprises an inner groove forming a cavity between the valve guide and the first valve stem, wherein the valve guide further comprises a valve guide aperture configured to fluidly connect the inner groove to the feeder channel, and wherein the inlet of the first valve stem is aligned with the valve guide aperture when the first valve is in a closed position.
