Abstract

See full text

A method and apparatus for controlling the logic of a spool valve including providing a valve block having a bore and a plurality of ports formed therein, the ports in fluid communication with the bore. A spool is selectively movable in the valve block and in fluid communication with the ports. A plurality of annular laminates is located on the spool, wherein each of the annular laminates comprises an outer diameter and an inner diameter. The outer diameter of each of the annular laminates seals against the bore and the inner diameter seals against the spool. A laminate plug is secured within the bore and compresses the annular laminates within the bore. Guiding the annular laminates by the spool controls the logic of the spool valve.
