Valve having axial and radial passages
View Patent ↗A valve includes a valve body ( 100 ) disposable within a chamber ( 103 ) of a housing ( 101 ) and capable of being fluidly sealed with respect to the housing ( 101 ) when the valve is closed. At least one radial passage ( 117 ) is disposed in the valve body ( 100 ). At least one axial passage ( 119 ) is disposed in the valve body ( 100 ) in fluid communication with the at least one radial passage ( 117 ). When the valve at least partially opens, a fluid path opens between the valve body ( 100 ) and the housing ( 101 ), which fluid path ( 301 ) in is fluid communication with the at least one radial passage ( 117 ), and fluid from within the housing ( 101 ) is capable of passing out of the at least one axial passage ( 119 ).
1. A valve comprising:
a valve body disposable within a chamber of a housing and capable of being fluidly sealed with respect to the housing when the valve is closed;
at least one radial passage disposed in the valve body;
at least one axial passage disposed in the valve body in fluid communication with the at least one radial passage;
a threaded engagement interface disposed on the valve body and engaged with the housing;
a seal disposed between the valve body and the housing and capable of preventing fluid in the fluid path from reaching the threaded engagement interface;
wherein, when the valve at least partially opens, a fluid path opens between the valve body and the housing, which fluid path in is fluid communication with the at least one radial passage, and fluid from within the housing is capable of passing out of the at least one axial passage.
2. The valve of claim 1 , further comprising:
at least one radial channel disposed in the valve body;
at least one axial channel disposed in the valve body in fluid communication with the at least one radial channel.
3. The valve of claim 1 , wherein the at least one radial passage is disposed at an angle other than 90 degrees from the at least one axial passage.
4. The valve of claim 1 , wherein the seal disposed on the valve body prevents fluid in the fluid path from leaking between the valve body and the housing.
5. The valve of claim 1 , further comprising a retention device disposed on the valve body and capable of retaining the valve body with the housing, wherein the retention device is disposed in the housing.
6. The valve of claim 1 , wherein the housing is a filter cap for an oil filter.
7. The valve of claim 1 , wherein the housing is a canister for an oil filter.
8. The valve of claim 1 , further comprising a tool engagement element capable of engaging a tool that operates to cause the valve to open by operating on an engagement interface disposed on the valve body and capable of engaging with the housing.
9. The valve of claim 8 , wherein the engagement interface is a threaded interface and wherein the tool engagement element rotates the valve body along the threaded interface.
10. The valve of claim 1 , further comprising a seal disposed on the valve body and capable of engaging with the housing at a position above the at least one radial passage when the valve is closed.
11. The valve of claim 1 , wherein the valve is utilized in a lubrication system for an internal combustion engine.
12. The valve of claim 5 , wherein the retention device is disposed in the housing and is capable of retaining the valve body with the housing when the valve fully opens.
13. The valve of claim 1 , wherein the seal is disposed between the engagement interface and fluid from within the housing at all times.
14. An apparatus comprising:
a housing having a chamber;
a drain valve including a valve body disposed in the chamber and fluidly sealed with respect to the housing when the valve body is in a closed position;
at least one radial drain channel disposed in the valve body;
at least one axial drain channel disposed in the valve body in fluid communication with the at least one radial drain channel;
at least one radial drain passage disposed in the valve body;
at least one axial drain passage disposed in the valve body in fluid communication with the at least one radial drain passage;
an engagement interface disposed on the valve body and engaged with the housing;
a seal disposed between the valve body and the housing and capable of preventing fluid in the fluid path from reaching the engagement interface;
wherein, when the drain valve at least partially opens by operation of the engagement interface, a fluid path opens between the valve body and the housing, which fluid path in is fluid communication with the at least one radial drain passage, and fluid from within the housing is capable of passing out of the at least one axial drain passage.
15. The apparatus of claim 14 , wherein the engagement interface is a threaded interface.
16. The apparatus of claim 14 , further comprising a retention device disposed on the valve body and capable of retaining the valve body with the housing.
17. The apparatus of claim 14 , wherein the housing is one of a filter cap for an oil filter and a canister for an oil filter.
18. The apparatus of claim 14 , further comprising a tool engagement element capable of engaging a tool that operates to cause the drain valve to open by rotating the valve body at the engagement interface.
19. The apparatus of claim 14 , further comprising a seal disposed between the valve body and the housing at a position above the at least one radial drain passage when the drain valve is closed.
20. The apparatus of claim 14 , wherein the at least one radial drain passage is disposed at an angle other than 90 degrees from the at least one axial drain passage.
21. A valve comprising:
a valve body disposable within a chamber of a housing;
at least one axial channel disposed at a first end of the valve body and having an opening in fluid communication with an environment inside the housing;
at least one radial channel in fluid communication with the at least one axial channel and disposed in the valve body;
at least one radial passage disposed in the valve body;
a first seal disposed on the valve body between the at least one radial channel and the at least one radial passage;
at least one axial passage in fluid communication with the at least one radial passage, disposed at a second end of the valve body, and having an opening in fluid communication with an environment outside the housing;
an engagement interface disposed on the valve body and capable of engaging with the housing;
a second seal disposed on the valve body between the at least one radial passage and the engagement interface, such that fluid in the fluid path is prevented from reaching the engagement interface;
wherein, when the valve at least partially opens, a fluid path opens between the valve body and the housing, such that the environment inside the housing is in fluid communication with the environment outside the housing.
22. The valve of claim 21 , further comprising a retention device disposed on the valve body and capable of retaining the valve body with the housing.
23. The valve of claim 21 , wherein the at least one radial passage is disposed at an angle other than 90 degrees from the at least one axial passage.
24. The valve of claim 21 , further comprising a tool engagement element capable of engaging a tool that operates to cause the valve body to open by rotating the valve body at the engagement interface.
