Document Type and Number:
Japanese Patent JP2001502776
Kind Code:
A
Abstract:
An improved apparatus and method for calibrating a float-type vent valve for use in an automobile fuel tank. The valve is provided with a calibration plate in the lower end thereof below the float, the calibration plate defining an axially-adjustable support for the spring which balances the float. The calibration plate includes a force probe aperture through which a force measuring device of known type can be inserted to measure the downward force of the spring-balanced float at a specified distance from closure, preferably a near-closed position. The calibration plate then is adjusted up or down as needed until a position is determined where the spring-balanced float is properly calibrated, and then the calibration plate is permanently secured in place on the valve body so that the valve remains calibrated.
