Abstract
A vent for a hub cap may include a screen and fluid channels for release of pressurized fluid in a hub cap.
Claims19
A hub cap vent plug comprising:
- a stub configured for sealing disposition in a vent opening of a hub cap, the stub forming a fluid chamber and one or more vent orifices extending from the fluid chamber, the one or more vent orifices extending radially from the fluid chamber and configured to allow communication of fluid from said fluid chamber to atmosphere;
- a shroud disposed at the end of the stub and extending over an opening for each of the one or more vent orifices;
- and
- a screen disposed in a path of fluid communication for connecting the interior of said hubcap to atmosphere, the screen being configured to capture vapor from fluid vented from the hub cap.

- a shroud formed as a unitary body with the stub and disposed at the end of the stub, the shroud extending over an opening for each of the one or more vent orifices;
- and
- a screen disposed in a path of fluid communication comprising said fluid chamber, the screen being configured to capture vapor from fluid vented from the hub cap when the vent plug is mounted to the hubcap.

- a screen disposed in a path of fluid communication comprising said fluid chamber, the screen being configured to capture vapor from fluid vented from the hub cap;
- and
- a gland disposed about the stub so as to seal the one or more vent orifices to flow from the inside of the hubcap to atmosphere at low pressure differentials but to allow fluid flow from the inside of the hubcap to atmosphere above a threshold pressure differential when the vent plug is mounted to the hub cap.
