Abstract

A dehydrator breather is provided that includes a vessel, a desiccant container, a valve housing coupled to the vessel, and a vent assembly coupled to the valve housing. The vent assembly includes screened ports disposed along a vertical axis of the vent assembly body that allow air to enter and exit the dehydrator breather. The vent assembly, along with a filter placed between a desiccant container and the valve housing, individually and jointly, prevent desiccant that escapes the desiccant container from clogging the valve assembly.

Claims (29)

1. A dehydrating breather apparatus, comprising:

a vessel comprising a desiccant container mounted within an interior of said vessel, said desiccant container comprising a desiccant and a heater;

a valve housing, said valve housing coupled to the vessel and secured with a mounting mechanism;

a seal positioned between the valve housing and the vessel;

a floating ball valve positioned within the valve housing, said floating ball valve comprising a first width that accommodates a floating ball and a second width that is narrower than the first width to prevent passage of the floating ball; and

a vent assembly, said vent assembly coupled to the valve housing and comprising:

a vent assembly body;

sintered bronze vents for trapping desiccant particles: and

at least one screened port, said screened port disposed along a vertical axis of the vent assembly body.

2. The dehydrating breather of claim 1 , wherein the at least one screened port is a plurality of screen ports aligned along a vertical axis of the vent assembly body.

3. The dehydrating breather of claim 1 , wherein the vent assembly has threaded portions.

4. The dehydrating breather of claim 3 , wherein the valve housing is threadably coupled to the vent assembly.

5. A dehydrating breather apparatus of claim 1 , wherein the seal positioned between the valve housing and the vessel comprises a gasket.

6. A dehydrating breather apparatus comprising:

a vessel comprising a desiccant container mounted within an interior of said vessel, said desiccant container comprising a desiccant and a heater;

a valve housing, said valve housing coupled to the vessel, and secured with a mounting mechanism;

a seal positioned between the valve housing and the vessel;

a floating ball valve positioned within the valve housing said floating ball valve comprising a first width that accommodates a floating ball and a second width that is narrower than the first width to prevent passage of the floating ball;

a vent assembly, said vent assembly coupled to the valve housing and comprising:

a vent assembly body; and

a muffler comprising at least one port, said port disposed along a vertical axis of the vent assembly body.

7. The dehydrating breather apparatus of claim 6 , wherein the seal positioned between the valve housing and the vessel comprises a gasket.

8. The dehydrating breather apparatus of claim 1 , wherein the desiccant container comprises a screened material.

9. The dehydrating breather apparatus of claim 1 , wherein a filter is positioned within the vessel.

10. The dehydrating breather apparatus of claim 1 , wherein the floating ball controls air flow into and out of the vessel.

11. The dehydrating breather apparatus of claim 6 , wherein the desiccant container comprises a screened material.

12. The dehydrating breather apparatus of claim 6 , wherein a filter is positioned within the vessel.

13. The dehydrating breather apparatus of claim 6 , wherein the floating ball controls air flow into and out of the vessel.

14. The dehydrating breather apparatus of claim 6 , wherein the ports of the muffler comprise a screen material to allow air to flow into and out of the vessel.
