Abstract
Official abstract text for this publication.
A cylinder head comprising a cavity for receiving a pre-chamber gas valve, wherein an opening extending substantially or completely around the pre-chamber gas valve forms an annular passage with a wall of the cavity, that surrounds the pre-chamber gas valve, wherein the annular passage is connected to at least one gas feed passage for supplying the pre-chamber gas valve with combustion gas, wherein the annular passage with at least one inclined gas passage is connected with the lower cavity of the pre-chamber gas valve.
First claim
Opening claim text (preview).
1 . A cylinder head comprising a cavity for receiving a pre-chamber gas valve, wherein a recess extending substantially or completely around the pre-chamber gas valve forms an annular passage with a wall of the cavity, that surrounds the pre-chamber gas valve, wherein the annular passage is connected to at least one gas feed passage for supplying the pre-chamber gas valve with combustion gas, characterized in that the annular passage with at least one inclined gas passage is connected with the lower cavity of the pre-chamber gas valve. 2 . A cylinder head as set forth in claim 1 , wherein the angle of the gas passage with respect to the symmetric axis of the valve body is of between 20° and 70°. 3 . A cylinder head as set forth in claim 1 , wherein a spark plug sleeve is fitted into the cylinder head so that the wall of the cavity, that with the pre-chamber gas valve forms an annular passage, is formed by the wall of the spark plug sleeve. 4 . A cylinder head as set forth in claim 1 , wherein the wall of the cavity, that with the pre-chamber gas valve forms an annular passage, is formed by a wall of the cylinder head itself. 5 . A cylinder head as set forth in claim 1 , wherein provided between the seat of a valve head of the pre-chamber gas valve and the mouth opening of the pre-chamber gas valve into a pre-chamber or between the seat of the valve head of the pre-chamber gas valve and the mouth opening of the pre-chamber gas valve into a passage leading to a pre-chamber is a space. 6 . A cylinder head as set forth in claim 5 , wherein the space is of a substantially pear-shaped configuration which narrows towards the pre-chamber. 7 . A cylinder head as set forth in claim 1 , wherein at its outside contour the pre-chamber gas valve has at least one projection whose flank that is towards the annular passage also delimits the annular passage and against the other flank of which bears a sealing means for sealing off the pre-chamber gas valve with respect to the bore. 8 . A cylinder head as set forth in claim 1 , wherein a spark plug is arranged in the cylinder head, wherein the spark plug and the pre-chamber gas valve are arranged in a common cavity of the cylinder head. 9 . A cylinder head as set forth in claim 7 wherein the spark plug and the pre-chamber gas valve are arranged in bores which mutually pass through each other.
