Abstract
A disk valve construction having a unitary valve body formed with an internal cavity to receive therein a rotor spool passed through the fluid inlet end of the valve body. A replaceable sleeve member at an outlet chamber of the valve includes a truncated conical portion followed by a cylindrical portion of the fluid discharge end of the sleeve. The sleeve member is maintained in position by way of pressure of the fluid.
Claims10
A valve including the combination of:
- a one-piece body having an internal cavity with an inlet and outlet for fluid;
- a rotator spool seated for rotational movement in the cavity of said valve body at a spaced location upstream of the fluid outlet, said inlet being sized to allow introduction of said rotator spool through the inlet to the cavity in the valve body wherein the rotator spool is seated, said rotator spool having a fluid passageway;
- an upstream disk locked to rotate with said rotator spool in the cavity of said valve body downstream of said rotator spool, said upstream disk having a fluid passageway for conducting fluid from the fluid passageway of said rotator spool;
- a downstream disk arranged in a face to face and confronting relation with said upstream disk in the cavity of said valve body, said downstream disk having a fluid passageway for conducting fluid from the fluid passageway in said upstream disk;
- means for interlocking said downstream disk member with said valve body;
- and
- means for rotating said rotator spool while said rotator spool is seated in the cavity of the valve body to bring the passageway in the upstream disk and the passageway in the downstream disk into and out of fluid conducting relationship.
