Abstract
In at least one embodiment, the present invention relates to a tire pressure monitor system located within the interior of a tire. The system comprises a housing having a wall forming a cavity and an interior wall forming an opening in fluid communication with the cavity, a tire pressure sensor located within the housing cavity, and a pressure cap inserted into the housing opening. The tire pressure sensor has an orifice for helping to sense tire pressure. The pressure cap comprises a wall having a portion that contacts the sensor and extends around the sensor orifice.
Claims19
A tire pressure monitor system located within the interior of a tire, the system comprising:
- a housing having a wall forming a cavity, the housing further having an interior wall forming a chamber in fluid communication with the cavity;
- a tire pressure sensor located within the housing cavity, the sensor having an orifice for helping to sense tire pressure;
- and
- a pressure cap inserted into the housing chamber, the pressure cap comprising a wall having a portion that contacts the sensor and extends around the sensor orifice, the pressure cap substantially blocking fluid communication between the senor orifice and the housing cavity while providing fluid communication between the senor orifice and the exterior of the housing.
A pressure cap for use with a tire pressure monitor, the monitor comprising a housing having a wall forming a cavity and an interior wall forming a chamber in fluid communication with the cavity and an air pressure sensor within the housing, the cap comprising:
- a cap wall which when inserted within the chamber extends between the housing wall and the sensor and extends around the sensor orifice and substantially blocks fluid communication between the sensor orifice and the housing cavity while providing fluid communication between the sensor orifice and the exterior of the housing.
A method for manufacturing a tire pressure monitoring system located within the interior of a tire, the method comprising:
- providing a housing having a wall forming a cavity and having an interior wall forming a chamber in fluid communication with the cavity;
- locating a tire pressure sensor within the housing cavity, the sensor having an orifice for helping to sense tire pressure;
- and
- locating a pressure cap into the housing chamber, the pressure cap comprising a wall having a portion that contacts the sensor and extends around the sensor orifice wherein the pressure cap substantially blocks fluid communication between the sensor orifice and the housing cavity, the pressure cap having at least a first conduit providing fluid communication between the sensor orifice and the exterior of the housing.
