| 20090242054 | SELECTABLE DETENT ASSEMBLY WITH NEUTRAL PROTECTION - A selectable detent assembly that has a housing with a plurality of passageways. Within the housing is a selector spool that is disposed within a selector passageway and is rotatable to provide a plurality of rotational positions including a no detent position, a kick down position, and a continuous detent position. A pilot check valve is disposed within the housing and provides a fluid flow path from a pilot passageway to the selector passageway and a detent passageway. A detent arming piston is disposed within the detent passageway and is connected to a directional control valve spool. Thus, depending on the rotational position of the selector spool, the selector spool can either provide a continuous flow path through the selector passageway to a tank, a flow path that is controlled by the axial position of the selector spool or prevent flow to the tank in order to operate the detent arming piston. | 10-01-2009 |
| 20100139793 | Hot Side Only Spring Return Used On Single Lever Hot/Cold Faucet With Locking Mechanism - A faucet includes a valve body having a cartridge receiving bore.

| 20120160354 | CERAMIC VALVE CORE WITH COLD/HOT SEPARATION POINT SNAPPING FUNCTIONS - An improved ceramic valve core with snapping functions for the cold/hot separation point having a valve casing, rotary driving pedestal, brake valve stem, rotating axle, base and ceramic valve set. A protruding portion is formed onto one end of the rotating axle and protruded outside of the flanged tube of the rotary driving pedestal. An elastomeric snapping clip is assembled between the reducing circular frame of the valve casing and the flanged tube. A snapping flange is formed from the snapping clip, such that elastic clamping effect is generated when the protruding portion is mated with the snapping flange under the action of the rotary driving pedestal. An elastic locator is set correspondingly to the snapping clip such that the snapping clip can be assembled in a limited state. Minimized components are required to form the ceramic valve core, thus lowering the cost, improving the control and extending service life. | 06-28-2012 |
| 20130068330 | FLOW PATH SWITCHING VALVE AND DISCHARGE CONTROL APPARATUS FOR FLUID MATERIAL USING THE SAME - A flow path switching valve has an injection side portion formed with an injection chamber and an outer valve seating surface, and a discharge side portion provided with a partition member formed with an inner valve seating surface. A discharge control block communicating with a discharge chamber is formed with a control flow path which is increased and decreased in volume by a discharge rod. To fill the control flow path with grease, a valve element closes an inner flow path and opens an outer flow path. On the other hand, to discharge the grease in the control flow path to the discharge chamber, the valve element closes the outer flow path and opens the inner flow path. After being supplied to the control flow path, the grease is supplied to the discharge chamber. | 03-21-2013 |
| 20130087232 | BALANCE VALVE HAVING AN ASYMMETRIC STRUCTURE - A balance valve is provided with an asymmetric structure.
