    Abstract: A valve arrangement for supplying air to a combustion chamber of an internal combustion engine includes a first valve, the first valve including a first valve head, a first valve stem assembly and an internal cavity, which is at least partly located in the first valve stem assembly, and a second valve partly arranged within the internal cavity of the first valve, the second valve including a second valve head and a second valve stem assembly, and being movable within the internal cavity between an upper, closed position and a lower, open position, wherein a junction seal extends over a junction between the first valve stem assembly and the second valve stem assembly when the second valve is in the closed position. A leakage preventing arrangement is arranged to hinder leakage of liquid from the outside of the junction seal from reaching in between the first valve stem assembly and the second salve stem assembly.

    Abstract: A gas feeding arrangement for feeding gas from an internal combustion engine cylinder chamber to a gas tank includes a feeding conduit assembly and a dedicated feeding valve. The feeding valve is adapted to assume an open condition in which it provides for gas transport in a direction from the cylinder chamber towards the gas tank, via the feeding conduit assembly. The gas feeding arrangement includes a one-way valve adapted to prevent gas transport from the gas tank to the cylinder chamber, via the feeding conduit assembly.

    Abstract: A valve arrangement is provided for supplying air to a combustion chamber of an internal combustion engine, the valve arrangement including a first valve, the first valve including a first valve head, a first valve stem and an internal cavity, which is partly located in the first valve stem and open towards a lower surface of the first valve head, a valve guide arranged to surround a portion of the first valve stem such that the first valve stem is movable in the valve guide along a longitudinal direction between an upper, closed position of the valve, and a lower, open position, in which open position air may be supplied to the combustion chamber past the first valve head, the valve guide including an air passage allowing supply of additional air to the combustion chamber via the internal cavity in the first valve, when the first valve is in its closed position. The valve arrangement includes a guide leakage preventing means for preventing liquid from leaking from a region externally of the first valve stem to the valve guide air passage.
