Patent number: 5417240Abstract: A head valve for maintaining a desired pressure head in a vehicle fuel tank which responds automatically to pressure changes in the filler pipe corresponding to a change from normal vehicle operation to a refueling operation to adjust the pressure head maintained by the head valve. In a vehicle fuel system including a filler pipe selectively opened and closed by a cap, the valve of the present invention responds to pressure changes near the filler pipe inlet upon removal of the cap to increase the pressure head it maintains in fuel tank 10 and prevent the fuel tank from being overfilled. When the refueling operation is completed and the cap is replaced, the change in pressure near the filler pipe inlet operates the valve to decrease its head valve closing force and reduce the pressure head maintained in the tank for normal vehicle operation.Type: GrantFiled: November 8, 1993Date of Patent: May 23, 1995Assignee: G.T. Products, Inc.Inventor: Robert P. Benjey
