VALVE ARRANGEMENT AND VALVE GUIDE

The present disclosure relates to a valve arrangement (200) for supplying air to a combustion chamber of an internal combustion engine, said valve arrangement comprising a first valve (206), said first valve (206) comprising a first valve head (208), a first valve stem (212) and an internal cavity (224), which is partly located in the first valve stem (212) and open towards a lower surface of the first valve head (208), a valve guide (214) arranged to surround a portion of said first valve stem (212) such that said first valve stem (212) is movable in said valve guide (214) 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 (208), said valve guide (214) comprising an air passage (242) allowing supply of additional air to said combustion chamber via the internal cavity (224) in said first valve (206), when said first valve (206) is in its closed position. The valve arrangement (200) comprises a guide leakage preventing means (300´, 300'') for preventing liquid from leaking from a region (301) externally of said first valve stem (212) to said valve guide air passage (242).
