Patent ID: 8196615

Claim:
A method of selectably extracting or filling a tire with a tool comprised the steps of: providing said tool, comprising: a first connection means; a corrosion-resistant ball valve with a handle, comprising a threaded connection and in fluid communication with said first connection means; a “T”-fitting comprising a first end having a threaded connection and in fluid communication with said ball valve, a central end, and a second end; a Schrader valve threadably connected to said central end of said “T”-fitting; and, a second connection means having a threaded connection and in fluid communication with said second end of said “T”-fitting; connecting said first connection means to a fluid pump hose and securing with a pipe clamp; connecting said second connection means to a fluid extraction hose and securing with a pipe clamp; connecting said ball valve to said first connection means with said threaded connection; connecting said first end of said “T”-fitting to said ball valve with said threaded connection; connecting said Schrader valve to said central end of said “T”-fitting; connecting said second end of said “T”-fitting with said threaded connection to said second connection means; and, selectively commencing an extraction means from or a filling means to said tire; wherein said commencing an extraction means step further comprises: orienting a valve stem portion of said tire to an accessible position; opening said ball valve using said handle; activating a suction pump in fluid communication with said fluid extraction hose, thereby extracting fluid from said tire and through said tool until said tire begins to cavitate; turning off said suction pump; closing said ball valve; injecting compressed air into said Schrader valve with an air hose, wherein said compressed air enters said tire through said tool until restoring a desired tire shape or a desired pressure; and, continuing to extract fluid from said tire and injecting said compressed air into said tire until a desired amount of fluid has been extracted from said tire.
