ABSTRACT:
A float assembly for a multifunction fuel vapor vent valve with a float having a recess formed in the upper surface of the float with a slot formed in the side of the float and communicating with the recess. A raised surface portion is formed in the bottom of the recess and downwardly extending projections are formed in the slot at the recess. A flexible wafer like valve disk is inserted in the slot and deformed or curled to pass under the projections and over the raised surface and into the recess. When fully received in the recess the disk returns to its flat configuration; and, the downward projections prevent removal without distortion. Radially inwardly projections about the recess retain the disk for limited lost motion in the direction of float movement.
