ABSTRACT:
An improved roll-over valve includes a hollow valve housing, a valve member in the valve housing, and a base for retaining the valve member in the valve housing. A ball is provided for moving the valve member within the valve housing. The valve member is positioned within the hollow valve housing for movement generally along a longitudinal axis between an outlet-opening and -closing position. The valve member includes a ball-receiving cup configured to define a first inclined ramp portion. The base retains the valve member within the housing and includes a second inclined ramp portion. The base is coupled to the valve housing the present the first and second inclined ramp portions in opposing spaced-apart relation to define a ball-receiving space therebetween. The ball is positioned in the ball-receiving space in substantially camming relation to each of the opposing first and second inclined ramp portions. The ball rides on both ramp portions to move the valve member to its outlet-closing position in response to tilting the valve housing about its longitudinal axis during a vehicle rollover and during abrupt changes to vehicle motion.
