EXCESS PRESSURE CLAIBRATED GUAGE
First Claim
1. An apparatus, comprising:
- a valve assembly, including;
a housing;
a valve portion disposed in the housing, the valve portion having an open position and a closed position; and
a variable pneumatic device located in the housing;
wherein air is allowed to pass through the valve portion when the valve portion is in the open position and at last partially flows into the variable pneumatic device to change the variable pneumatic device between a first configuration and a second configuration.

Abstract
A valve assembly having a housing, and a valve portion disposed in the housing, where the valve is able to change between an open position and a closed position. The valve assembly also includes a variable pneumatic device disposed in the housing, which is able to change between a first configuration and a second configuration, and an inner cavity in fluid communication with the housing. An exhaust aperture is formed as part of the housing, and as pressure builds in the variable pneumatic device, the variable pneumatic device changes from the first configuration to the second configuration such that air is prevented from flowing around the variable pneumatic device, and air flowing through the valve body passes through the exhaust aperture.

15. A valve assembly for preventing the over inflation of a tire, comprising:
-
a housing; a valve body disposed in the housing; a valve seat formed as part of the valve body; a valve member selectively in contact with the valve seat such that the valve member is in contact with the valve seat when the valve member is in a closed position, and the valve member moves away from the valve seat when the valve member is moved to an open position; a pneumatic muscle having a variable volume cavity such that the pneumatic muscle is able to change between a first configuration and a second configuration, the pneumatic muscle disposed in the housing in proximity to the valve body; an inner cavity, the housing in fluid communication with the inner cavity; and an exhaust aperture formed as part of the housing; wherein air flows through the valve body and around the pneumatic muscle when the valve member is in the open position and the pneumatic muscle is in the first configuration, and as pressure builds in the inner cavity, the pneumatic muscle expands, such that when the pneumatic muscle is in the second configuration, a portion of the pneumatic muscle contacts the valve body and prevents air from flowing around the pneumatic muscle, and air flowing through the valve body passes through the exit aperture. - View Dependent Claims (16, 17, 18, 19)
