Abstract
A high-pressure spray nozzle assembly (10) has a nozzle body (20) and nozzle cap (30), which are operatively coupled and co-operatively house a retainer (40) having a clasp (42) for retaining wear components (50). The nozzle cap (30) has an open-stepped detent (32) formed in relief on an internal peripheral surface of the nozzle cap (30), which operatively permits sealing of the retainer (40) against the nozzle cap (30) as a consequence of hydraulic pressure applied by fluid delivered through the spray nozzle assembly (10).
Claims26
A high-pressure spray nozzle assembly having a nozzle body and nozzle cap, which are operatively coupled and co-operatively house a retainer having a clasp for retaining wear components, wherein the nozzle cap has an open-stepped detent which is formed in relief on an internal peripheral surface of the nozzle cap, wherein the open-stepped detent permits sealing of the retainer against the nozzle cap as a consequence of hydraulic pressure applied by fluid delivered through the high-pressure spray nozzle assembly during operation.
A unitary retainer assembly for a high-pressure spray nozzle assembly comprising:
- a retainer having a clasp for releasably trapping wear components, and a sleeve having a radial detent;
- a check valve assembly comprising a valve seal attached to a valve body having a radial detent;
- and a helical spring which at one terminal end removably attaches to the radial detent formed on the sleeve of the retainer, and at its opposite terminal end removably attaches to the radial detent formed on the valve body of the check valve.
