Abstract

Claims (36)

1. A fluid jet for providing fluid under pressure to a desired location, said fluid jet comprising:

a valve body having a cavity therein, said valve body comprising:

at least one wall integral with said valve body and extending inwardly within said cavity so as to at least partially define a valve element retaining region extending longitudinally within at least a portion of said body wherein said at least one wall includes a semi-circular wall portion partially defining said valve element retaining region;

at least one fluid passage extending longitudinally within at least a portion of said valve body and in fluid communication with at least a portion of said valve element retaining region;

at least one fluid-exiting aperture through said valve body in fluid communication with said at least one fluid passage;

wherein said valve body is die cast as a one-piece component;

a fluid pressure actuated valve element located within said valve retaining region and moveable longitudinally therealong between a valve-open position and a valve-closed position, said valve element retaining region preventing said valve element from vacillating within said valve body along the length of said valve element retaining region in response to fluid flow during said valve-open position wherein said valve element is actuated to a valve-open position along said valve element retaining region in response to a predetermined fluid pressure acting on said valve element;

a cap having a fluid-entering aperture therethrough, said cap connected to said valve body coaxially with said valve element retaining region so as to retain said valve element therein, said valve element being spring biased against said aperture in a valve-closed position; and

at least one nozzle connected to said at least one fluid-exiting aperture so as to direct fluid under pressure to a desired location.

2. The fluid jet of claim 1 wherein said valve element is a ball.

3. The fluid jet of claim 1 wherein said fluid is oil.

4. The fluid jet of claim 1 wherein said valve body is die cast from powdered metal.

5. The fluid jet of claim 1 wherein said valve element is a ball.

6. The fluid jet of claim 1 wherein a compression spring biases said valve element against aperture in a valve-closed position.

7. The fluid jet of claim 1 wherein said fluid is oil.

8. An oil jet for providing oil under pressure to a desired location, said oil jet comprising:

a valve body having a cavity therein and an orifice;

a wall integral with said valve body and extending inwardly within said cavity, at least a portion of said wall defining a valve element retaining region extending longitudinally within at least a portion of said valve body, said valve element retaining region preventing a valve element from vacillating within said valve body along the length of said valve element retaining region wherein said wall includes a semi-circular wall portion partially defining said valve element retaining region;

an oil passage at least partially defined by said wall and extending longitudinally within said valve body in fluid communication with at least a portion of said valve element retaining region;

an oil-exiting aperture through said valve body in fluid communication with said oil passage;

a nozzle connected to said oil-exiting aperture so as to direct oil under pressure to a desired location;

an oil pressure actuated valve element located within said valve retaining region and moveable longitudinally therealong between a valve-open position and a valve-closed position, said wall preventing said valve element from vacillating in response to oil flow during a valve open position;

a spring located within said valve element retaining region and biasing said valve element toward said orifice wherein said valve element is spring biased against said oil-entering aperture during said valve-closed position and is movable against said spring force within said valve element retaining region during said valve-open position in response to a predetermined oil pressure; and

a cap having an oil-entering aperture therethrough, said cap coaxially connected to said valve body relative to said orifice so as to retain said valve element therein.

9. An oil jet for providing oil under pressure to a desired location, said oil jet comprising:

a valve body having a cavity therein and an orifice;

first and second confronting walls integral with said valve body and extending inwardly within said cavity, at least a portion of each of said walls defining a valve element retaining region extending longitudinally within at least a portion of said valve body, wherein said first and second walls each include a semi-circular wall portion, said confronting semi-circular wall portions partially defining said valve element retaining region, said valve element retaining region preventing a valve element from vacillating within said valve body along the length of said valve element retaining region;

first and second oil passages at least partially defined by said walls and extending longitudinally within said valve body in fluid communication with at least a portion of said valve element retaining region;

first and second oil-exiting apertures through said valve body in fluid communication with corresponding first and second oil passages; and

first and second nozzles connected to said corresponding first and second oil-exiting apertures so as to direct oil under pressure to a desired location.

10. The oil jet of claim 9 further comprising:

a spring located within said valve element retaining region and biasing said valve element to a valve-closed position.

11. The oil jet of claim 9 wherein said valve body is die cast from powdered metal.

12. The oil jet of claim 9 wherein said valve element is a ball.

13. The oil jet of claim 9 further comprising:

a cap having a fluid-entering aperture coaxially connected to the valve body.
