Definitions
- This invention relates tocylinder heads or covers for internal combustion engines, and more particularly for double-actingengines, of the kind in which the head or cover is provided with a central opening which is surrounded by an annular water chamber and accommodates for example a piston rod, and with one or more other openings or sockets for valves, the cylinder head or cover being clamped to the cylinder by a clamping ring through holes in which pass retaining bolts connecting the ring to the cylinder.
- a cylinder head according to the present invention for an internal combustion engine of the kind referred to above comprises in combination with the clamping ring through which pass the retaining bolts, a water-cooled cylinder head or cover having an annular water chamber a part of the outer circumferential wall of which remote from the cylinder is surrounded by the clamping ring while a part adjacent to the cylinder is of larger diameter soas to lie adjacent to the retaining bolts and form a shoulder on which the clamping ring bears, this enlarged part of the circumferential wall ofv the annular water chamber being provided with a radially projecting portion extending between the Y retaining bolts adjacent to each valve socket so as to increase the water space around the sockets.
- the cylinder head comprises a body portion a provided with an opening I) for a piston rod and with sockets 0 for fuel injection valves which pass through the annular water cooling chamber cl surrounding the central opening 7).
- the outer circumferential wall of the part of the cylinder head a which lies adjacent to the cylinder is of larger diameter than that surrounded by the clamping ring 6 so that it lies adjacent to the retaining bolts f and forms a shoulder on which bears the clamping ring.
- this enlarged part of the circumferential wall of the cylinder head a is provided with protruding portions in the neighborhood of each of the valve sockets 0 so as to increasethe width of the cooling chamber around these sockets.
- Water isdelivered to the cooling chamber cl through a pipe 9 the outlet end of which is conveniently bent so that the water is delivered substantially tangentially with re spect to the cooling chamber so as to cause the water in this chamber to circulate in the direction of the arrows and thus increase its cooling action.
