Claim 8:
9. An automatic tire inflator assembly for inflating a tire to a pre-determined pressure, said assembly comprising:
an input hose being fluidly attachable to an air source wherein said input hose is configured to receive compressed air from the air source, said input hose having a first end and a second end, said second end having a quick release coupler being fluidly coupled thereto, said quick release coupler for releasably engaging the air source to fluidly couple said input hose to the air source;
an output hose being fluidly attachable to an air stem of an inflatable tire, said output hose having a primary end and a secondary end, said secondary end having a quick release coupler for releasably engaging the air stem to fluidly couple said output hose to the air stem;
a control unit being fluidly coupled to said input hose wherein said control unit is configured to receive the compressed air from the air source, said control unit being fluidly coupled to said output hose wherein said control unit is configured to inflate the inflatable tire, said control unit sensing air pressure for sensing the pressure of the compressed air received from the air source, said control unit comprising:
a housing, said housing having a pair of longitudinal sides and a pair of ends extending between said pair of longitudinal sides, said input hose extending from one of said ends of said housing, said housing having an air conduit being integrated therein, said air conduit having an intake and an exhaust, said first end of said input hose being fluidly coupled to said intake, said primary end of said output hose being fluidly coupled to said exhaust;
a control circuit being positioned in said housing, said control circuit receiving a shut off input;
a shut off valve being fluidly coupled to said air conduit, said shut off valve being electrically coupled to said control circuit, said shut off valve being actuatable into a closed condition such that said shut off valve inhibits air from flowing through said conduit, said shut off valve being actuatable into an open condition such that said shut off valve permits air to flow through said conduit, said shut off valve being actuated into said closed condition when said control circuit receives said shut off input, said shut off valve being actuated into said open condition when said control circuit does not receive said shut off input;
a pressure sensor being fluidly coupled to said air conduit wherein said pressure sensor is configured to sense air pressure within said air conduit, said pressure sensor being electrically coupled to said control circuit, said control circuit receiving said shut off input when said pressure sensor senses air pressure that exceeds a pre-determined threshold pressure;
a speaker being coupled to said housing wherein said speaker is configured to emit an audible alert outwardly therefrom, said speaker being electrically coupled to said control circuit, said speaker being turned on when said control circuit receives said shut off input wherein said speaker is configured to audibly alert a user;
a light emitter being coupled to said housing for emitting light outwardly therefrom, said light emitter being electrically coupled to said control circuit, said light emitter being turned on when said control circuit receives said shut off input wherein said light emitter is configured to visually alert the user;
a power switch being movably coupled to said housing, said power switch being electrically coupled to said control circuit, said power switch turning said control circuit on and off; and
a power supply being positioned in said housing, said power supply being electrically coupled to said control circuit, said power supply comprising at least one battery; and
a gauge being fluidly coupled to said control unit wherein said gauge is configured to receive the compressed air, said gauge being settable to determine said pre-determined threshold pressure, said control unit being turned off when said gauge measures air pressure that exceeds said pre-determined threshold pressure wherein said control unit is configured to inflate the inflatable tire to a desired air pressure, wherein said gauge is coupled to said housing such that said gauge is positioned offset from said housing adjacent to said input hose, said gauge having a rotatable bezel, a pressure needle and a threshold needle, said rotatable bezel being rotatable around said gauge thereby facilitating said threshold needle to be aligned with a desired pressure displayed on said gauge for determining said pre-determined threshold pressure, said gauge being electrically coupled to said control circuit thereby facilitating said control circuit to communicate said pre-determined threshold pressure to said pressure sensor, said gauge having a supply hose, said supply hose extending through said housing and being fluidly coupled to said air conduit.
