Abstract
A cylinder head (12) comprising a guideway in which is located a rotatable valve (10,12) comprising a fluid port operable to effect fluid communication between a cylinder and a fluid manifold in the guideway, whereby rotation of the valve effects alignment of the fluid port with the combustion chamber of a cylinder (4) to enable fluid flow between the valve (10, 12) and a cylinder (4), and wherein the cylinder head (2) further comprises a seal (22) which, in use, is movable from a first, non-sealing position in which the seal (22) is biased away from the valve (10, 12), and a second, sealing position in which the seal (22) is biased onto the valve by gaseous pressure from within a cylinder (4).
Claims33
A cylinder head for mounting on a cylinder of a combustion engine, the cylinder head comprising a guideway in which is located a rotatable valve comprising a fluid port operable to effect fluid communication between a cylinder and a fluid manifold in the guideway, whereby rotation of the valve effects alignment of the fluid port with the combustion chamber of a cylinder to enable fluid flow between the valve and a cylinder, and wherein the cylinder head further comprises a seal which, in use, is movable from a first, non-sealing position in which the seal is biased away from the valve, and a second, sealing position in which the seal is biased onto the valve by gaseous pressure from within a cylinder.
The cylinder head for mounting on a cylinder of a combustion engine, the cylinder head comprising a single guideway in which is located a rotary valve comprising a fluid inlet and a fluid outlet, operable to effect fluid communication between a cylinder and a corresponding inlet manifold and outlet manifold in the guideway, wherein rotation of the valve effects alignment of the fluid inlet and fluid outlet with a combustion chamber of a cylinder to enable, in use, fluid flow between the valve and a cylinder, and wherein the fluid inlet and fluid outlet are axially spaced along the rotary valve.
