Abstract

The assembly has a valve 3 and a valve cate 1, affording a seat 10 against which a face 11 of the head of the valve seats and includes means 8 for cooling the seat. In order to make the valve face 11 and the valve seat 10 resistant to corrosion, they are each provided with armouring, the armouring of the valve face being harder than that of the valve seat. Owing to the relative hardness of the armourings, any combustion residue will not be deposited on the valve face but it may be pressed into the valve seat. However, the seat will be at a temperature at which the combustion residues will not corrode the valve seat. The valve seat may be provided by an annular element 9 welded to the cage. <IMAGE>
