发明名称 RETAINER AND O-RING FOR VALVE SEALING
摘要 A system for positioning a seal member on a movable valve stem. The system includes an O-ring surrounding a lower portion of a movable valve stem. A snap-on retaining collar is pushed into place along the valve stem. A lower edge of the collar contacts the O-ring. The interaction between the snap-on collar and the O-ring prevents the O-ring from flexing outwardly and becoming dislodged from the valve stem. The snap-on retaining collar can be formed from various materials, such as but not limited to plastic.
