20150129787 | RETAINER AND O-RING FOR VALVE SEALING - 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. | 05-14-2015 |
20100097165 | Solenoid Assembly with Shock Absorbing Feature - A solenoid assembly includes a solenoid having a coil provided with a passageway and a plunger movable within the passageway upon application of electrical power to the coil. A frame holds the solenoid and includes a backstop movably mounted in the frame extending into the coil passageway. The backstop is selectively engaged by the plunger such that the backstop and the plunger are subjected to an impact therebetween. A resilient dampening element is positioned between the frame and the backstop for cushioning the impact between the backstop and the plunger. | 04-22-2010 |
20090038690 | SOLENOID MOUNTING ARRANGEMENT FOR LIQUID DISPENSING VALVE - A solenoid valve has a valve body with an inlet, an outlet and a valve chamber therebetween. A valve member is selectively engagable with the valve chamber for controlling the flow of fluid from the inlet to the outlet. A solenoid assembly is mounted upon the valve member for moving the valve member to control the flow of fluid from the inlet to the outlet. The solenoid assembly includes a solenoid and a frame for holding the solenoid. The solenoid assembly is connected to the valve body such that the frame is rotatable and slidable away from the valve body to permit access to and slidable removal of the solenoid from the valve member. | 02-12-2009 |
