Digital tire pressure gauge with bleed valve
First Claim
1. A digital tire pressure gauge comprising:
- a housing having a first and a second end;
a port at said first end of said housing, said port adapted to engage with and open a needle valve of a tire valve stem;
a sensor housing disposed in said housing and defining an air chamber therein;
a pressure sensor disposed in said sensor housing;
a processor in electronic communication with said pressure sensor;
a bleed valve disposed in said sensor housing, said bleed valve comprising;
a tube having a first end disposed in an opening of a wall of said sensor chamber;
a stem comprising, at a first end, a head protruding outside said tube and adapted to cover said opening in the wall of said sensor chamber;
a spring in contact with said stem and said tube, wherein said spring is adapted to provide contact between said head and said opening; and
a bleed lever in contact engagement with a second end of said stem,wherein, when said port is coupled to the tire valve stem, in a first operational mode, said bleed valve is closed and an air pressure measurement is obtained, and, in a second operational mode, said bleed lever, when pressed, causes said bleed valve to open and to allow air to be bled out from the tire via the pressure gauge.

Abstract
A digital tire pressure gauge has a housing having a first and a second end. A port at the first end of the housing is adapted to engage with and open a needle valve of a tire valve stem. The gauge also includes a pressure sensor and a processor in electronic communication with the pressure sensor. A bleed valve is disposed in the housing and a bleed lever is in contact engagement with the bleed valve. When the port is coupled to the tire valve stem, in a first operational mode, the bleed valve is closed and an air pressure measurement is obtained. In a second operational mode, pressing the bleed lever causes the bleed valve to open and to allow air to be bled out from the tire via the pressure gauge.

22. A method for bleeding excess air from a tire comprising the steps of:
-
engaging a port of a tire pressure gauge to a valve stem of the tire, the tire pressure gauge comprising; a housing having a sensor housing disposed therein, wherein said sensor housing defines an air chamber; a bleed valve disposed in said sensor housing and in a switchable fluidic communication with the air in the tire; a bleed lever in contact engagement with said bleed valve, wherein said bleed lever is adapted to switch on and off the fluidic communication of said bleed valve with the air in the tire; and while keeping said port of said tire pressure gauge engaged with the valve stem, pressing said bleed lever to cause at least some air to bleed out of the tire via said bleed valve in said pressure gauge. - View Dependent Claims (23, 24, 25, 26)
