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.
