This pressure cuff tire pump device, provides a unique way of inflating an automobile tire, without removing the tire or jacking up the automobile. Primarily, it consists of a flexible rubber casing containing a bladder, which is secured to the wheel having the tire that is to be inflated, by a pair of adjustable straps. The device also includes a hose attached to the bladder, so as to fill the tire with air from the bladder when the automobile is moving. The device further includes an intake valve for receiving air at atmospheric pressure, and an air output valve is included in the hose, to enable the air received in the bladder, to travel into the tire by its valve stem, and the pumping action is supplied by the tire rotating when the automobile is being driven. The device further includes a pressure relief valve, to prevent excessive build-up of air pressure within the bladder and casing of the device.
A pressure cuff tire pump device, comprising, a resilient flexible casing, an inflatable bladder received in said casing, for receiving air at atmospheric pressure and discharging it under pressure into a vehicle tire, a pair of straps secured to said casing, for fastening said casing to a vehicle wheel and its tire, a flexible hose secured to said bladder, for air transfer into said tire, and three valves secured in said bladder, for controlling the air entering and being discharged from said bladder.
