Abstract
A fluid spray nozzle tip can include a feed hole body that defines at least one feed hole and a spray outlet, the at least one feed hole being in direct fluid communication with the spray outlet without also being in fluid communication with an upstream spin chamber. The at least one feed hole can be a plurality of feed holes, wherein the tip further includes a pintle sealing surface body extending from the feed hole body and configured to allow a pintle to seal against a sealing surface thereof.
Claims20
A fluid spray nozzle tip, comprising:
- a feed hole body that defines at least one feed hole and a spray outlet, the at least one feed hole being in direct fluid communication with the spray outlet without an upstream spin chamber, wherein the at least one feed hole is a plurality of feed holes, wherein the tip further includes a pintle sealing surface body extending from the feed hole body and configured to allow a pintle to seal against a sealing surface thereof.
A fluid spray nozzle, comprising:
- a housing defining a flow cavity;
- a nozzle tip disposed at an end of the housing, comprising:
- a feed hole body that defines a plurality of feed holes;
- and
- a pintle sealing surface body extending from the feed hole body and configured to allow a pintle to seal against a sealing surface thereof, and
- wherein at least one of the feed hole body and the pintle sealing surface body define a spray outlet in direct fluid communication with the plurality of feed holes without an upstream spin chamber;
- and
- a pintle disposed within the flow cavity and configured to axially actuate therein between an open position where the feed holes are in fluid communication with the flow cavity, and a closed position where the pintle interacts with the pintle sealing surface to seal the feed holes from the flow cavity.
5 more elements
A fluid spray nozzle tip, comprising:
- a feed hole body that defines at least one feed hole and a spray outlet, the at least one feed hole being in direct fluid communication with the spray outlet without an upstream spin chamber, wherein the at least one feed hole is defined at a non-normal angle relative to a centerline axis of the nozzle tip where the at least one feed hole intersects with the spray outlet.
