Definitions
- the outer surface 62 defines a pair of grooves 64 and 66 which effectively define lands 70, 72 and 74.
- the lands 70, 72 and 74 engage the inner surface of the spool valve 18.
- the grooves 64 and 66 carry an adhesive such as an epoxy resin which is utilized to secure the cylindrical sleeve 60 in place within the spool valve 18.
- the sleeve 60 is split as is shown at 76 and also defines a beveled edge 78 and 80 at the top and bottom thereof as viewed in Figs. 3 and 6.
