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;
an insert co-molded with said sensor housing;
a stem tube in engagement with said insert; and
a stem positioned in said stem tube, said stem comprising;
a first head protruding outside said stem tube and adapted to cover an opening of said stem tube; and
a second head positioned inside said stem tube; and
a spring disposed about said stem and seated on said second head; and
a bleed lever in contact engagement with 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.
