Abstract
Embodiments of the present invention allow an operator to select one, two, or more tires in the system to have their individual pressure measured or equalized and set by either connecting it to a compressed air supply or by bleeding out excess air to reduce tire pressure. This is all done by operating the push-button valves on the gauge handle to read and/or bleed when the push-button valve for reading is not actuated; it isolates the gauge from the compressor's air pressure during a filling phase to prevent its being damaged.
Claims19
A tire pressure monitoring system comprising:
- a first handheld manifold having at least two finger grips, first and second push button valves, and a plurality of openings;
- a second manifold having a plurality of threaded bores, a plurality of toggle valves, and a plurality of tubes which connect the second manifold to at least one tire;
- at least one tube which couples the first handheld manifold to the second manifold;
- and
- a pressure gauge.
A tire pressure monitoring system comprising:
- a handheld manifold having at least a first and second push button valves, and a plurality of openings;
- at least one length of tubing connecting the first handheld manifold to at least one tire;
- and
- a pressure gauge coupled to the handheld manifold.
A method of using the tire pressure monitoring system comprising the steps:
- (a) attaching an air compressor to a first handheld manifold;
- (b) coupling a second manifold to the first manifold with a tube;
- (c) coupling a pressure gauge to the first handheld manifold;
- (d) coupling an interface fitting to at least one tire on a vehicle;
- (e) coupling the interface fitting to a least one of a plurality of toggle valves by connecting one end of a tube to the interface fitting and the other end of the tube to a threaded bore disposed on the top of a second manifold;
- (f) engaging the desired toggle valve to open a connection between the corresponding tire and the second manifold;
- and
- (g) applying pressure to one of a pair of push buttons valves on the first handheld manifold wherein the pair of push button valve controls airflow to and from the tire.
