Abstract
A sleeve valve assembly. The assembly includes a valve seat, a sleeve valve and an oil path-defining piece. The sleeve valve includes a distal end with a cavity. The distal end contacts the valve seat when the sleeve valve is located in a closed position. The oil path-defining piece includes an inlet port, an outlet port and a plurality of cooling passages. The flange of the sleeve valve is slidably in contact with the oil path-defining piece such that cooling fluid travelling into the inlet port and through the cooling passages enters into the cavity before exiting out the exit port.
Claims25
A sleeve valve assembly, comprising:
- a valve seat;
- a sleeve valve having a distal end with a cavity, wherein the distal end contacts the valve seat when the sleeve valve is located in a closed position;
- and
- a fluid path-defining piece having an inlet port, an outlet port and a plurality of cooling passages;
- wherein the sleeve valve is slidably in contact with the fluid path-defining piece and cooling fluid traveling through the fluid path-defining piece travels into the inlet port and through the cooling passages before entering into the cavity and exiting out the outlet port.
A sleeve valve assembly for an internal combustion engine, comprising:
- a cylindrical sleeve valve at least in part defining a combustion chamber of the internal combustion engine, the cylindrical sleeve valve comprising a distal end that contacts a valve seat when the cylindrical sleeve valve is in a closed position;
- and
- a fluid path-defining piece at least partially surrounding the cylindrical sleeve valve and including an inner surface facing the cylindrical sleeve valve, the fluid path-defining piece including:
- an inlet port,
- an outlet port, and
- a plurality of passages defined between the inner surface of the fluid path-defining piece and the sleeve valve for fluid to pass between the inlet port and outlet port, the inlet port, the outlet port, and the plurality of passages being arranged such that cooling fluid traveling through the plurality of passages moves toward the distal end of the cylindrical sleeve valve.
A method comprising:
- defining a combustion chamber of an internal combustion engine at least in part by a sleeve valve, the sleeve valve being slidably in contact with a fluid path-defining piece of the internal combustion engine, the fluid path-defining piece at least partially surrounding the sleeve valve and comprising an inlet port, an outlet port, an inner surface facing the sleeve valve, and a plurality of passages defined between the inner surface and the sleeve valve;
- and
- passing fluid through the plurality of passages between the inlet port and outlet port.
