Quick disconnect devices for spray nozzles
View Patent ↗A nozzle assembly includes a nozzle body defining an inlet and an opposed spray outlet for producing a spray of fluid supplied at the inlet. The nozzle body includes a radially outward extending retainer feature. An adapter having an adapter bore therethrough is provided for supplying fluid to the inlet of the nozzle body. The nozzle body is engaged within the bore of the adapter. A retainer radially outward of the adapter and nozzle body includes a retainer feature engaged to the retainer feature of the nozzle body to hold the nozzle body and adapter body together. A sleeve is engaged to the retainer radially outward thereof to prevent disengagement of the retainer features of the nozzle body and retainer. The sleeve and retainer are configured for relative movement for releasing the retainer features of the nozzle body and retainer for removal of the nozzle body from the adapter.
1. A nozzle assembly comprising:
a nozzle body defining an inlet and an opposed spray outlet for producing a spray of fluid supplied at the inlet, wherein the nozzle body includes a radially outward extending retainer feature;
an adapter having an adapter bore therethrough for supplying fluid to the inlet of the nozzle body, wherein the nozzle body is engaged in fluid communication with the bore of the adapter;
a retainer radially outward of the adapter and nozzle body and including a retainer feature engaged to the retainer feature of the nozzle body to hold the nozzle body and adapter together; and
a sleeve engaged to the retainer radially outward thereof to prevent disengagement of the retainer features of the nozzle body and retainer, wherein the sleeve and retainer are configured for relative movement for releasing the retainer features of the nozzle body and retainer for removal of the nozzle body from the adapter;
wherein the sleeve is configured for movement between a first position in which the sleeve is engaged outboard of the retainer feature of the retainer to prevent disengagement of the retainer features of the nozzle body and retainer, and a second position in which the sleeve is axially retracted from the retainer feature of the retainer to allow disengagement of the retainer features of the nozzle body and retainer for removal of the nozzle body from the adapter;
wherein the adapter includes a retainer feature engaged with the retainer feature of the nozzle body, and wherein in the first position of the sleeve, the retainer feature of the retainer captures the retainer features of the nozzle body and adapter to prevent disengagement of the nozzle body;
wherein the retainer feature of the adapter extends radially outward, wherein the retainer features of the nozzle body and adapter abut one another when engaged with the sleeve in the first position, and wherein the retainer feature of the adapter extends radially outward beyond the retainer feature of the nozzle body.
2. A nozzle assembly as recited in claim 1 , wherein the retainer features of the nozzle body and adapter abut one another at an interface that is oblique with respect a longitudinal axis defined by the nozzle body.
3. A nozzle assembly as recited in claim 1 , wherein a groove is defined on an outlet portion of the nozzle body for gripping of the nozzle body for removal of the nozzle body from the adapter.
4. A nozzle assembly as recited in claim 1 , further comprising a sleeve spring engaged to the sleeve to bias the sleeve toward the first position.
5. A nozzle assembly comprising:
a nozzle body defining an inlet and an opposed spray outlet for producing a spray of fluid supplied at the inlet, wherein the nozzle body includes a radially outward extending retainer feature;
an adapter having an adapter bore therethrough for supplying fluid to the inlet of the nozzle body, wherein the nozzle body is engaged in fluid communication with the bore of the adapter;
a retainer radially outward of the adapter and nozzle body and including a retainer feature engaged to the retainer feature of the nozzle body to hold the nozzle body and adapter together; and
a sleeve engaged to the retainer radially outward thereof to prevent disengagement of the retainer features of the nozzle body and retainer, wherein the sleeve and retainer are configured for relative movement for releasing the retainer features of the nozzle body and retainer for removal of the nozzle body from the adapter;
wherein the sleeve is configured for movement between a first position in which the sleeve is engaged outboard of the retainer feature of the retainer to prevent disengagement of the retainer features of the nozzle body and retainer, and a second position in which the sleeve is axially retracted from the retainer feature of the retainer to allow disengagement of the retainer features of the nozzle body and retainer for removal of the nozzle body from the adapter;
wherein the sleeve includes a locking feature configured to lock the sleeve in the first position by twisting the sleeve about a longitudinal axis defined by the nozzle body.
