| 20130199626 | WATER-SAVING DEVICE STRUCTURE - A water-saving device structure is provided. When the pressure of an entry water is high, a water-barrier sheet body is pressed to cause a downwardly-moved elastic stopping portion to block a water-inflow opening of a water-outflow seat body, so that the water flow is conducted to a water-outflow opening through a water-conducting opening of the water-barrier sheet body. When the pressure of the entry water is low, the entry water is conducted to the water-outflow opening via one path traveling from the water-conducting opening of the water-bather sheet body to the water-outflow opening of the water-outflow seat body and the other path traveling along the clearances of stopping wall portions of the water-outflow seat body, a water-storage circular slot portion, the water-inflow openings of the water-outflow seat body and the water-outflow opening of the water-outflow seat body. Therefore, the outflow water with steady flow rate can be obtained. | 08-08-2013 |
| 20140230919 | VALVE SEAL FOR A DIVERTER ASSEMBLY - A valve for controlling the flow of a waste gas stream received from an industrial process is disclosed. The valve includes ducts to permit entry of the stream for removal of harmful VOCs and exit of the treated gas stream to the atmosphere. The valve includes several open frames extending radially from a central axis. A distribution blade mounted on the axis rotates between two positions to control the flow of the stream through the open frames during processing. A seal ring mounted to each open frame forms a seal with the distribution blade when in contact with the frame. Pressurized air delivered within the seal ring during contact with the blade acts to significantly reduce of the gas stream from within the valve to the atmosphere during operation. | 08-21-2014 |

| 20080210309 | DIVERTER VALVE - A diverter valve may include a body portion and a lid portion. The lid and body portions may define a fluid chamber. The lid portion may include a first stop and a second stop. A closure member may at least partially be received within the fluid chamber. A movable member, such as a handle, may be operatively associated with closure member. The movable member may be selectively movable relative to the lid portion between the first and second stops. A stop member may be selectively positioned on the lid portion. When positioned between the first and second stops, the stop member may limit movement of the movable member to between the stop member and one of the first and second stops. The first stop, the second stop, or both, may also comprise a stop member. | 09-04-2008 |
| 20100012197 | AUTOMATIC WATER DIVERTER - An automatic water diverter is provided, in which a flange is disposed on a passage of a valve seat, so as to form a through hole. In addition, an upper and a lower side of the passage are respectively connected to an upper and a lower outlet pipe, and two sides of the passage are respectively connected to an inlet pipe. A diverting assembly is disposed within the passage, and a seal is fixed on a diverting rod of the diverting assembly, so as to seal the through hole. Moreover, a check valve is disposed on a lower side of the diverting rod. A sliding sleeve is disposed between the tapered seal and the check valve, and has a via hole corresponding to the inlet pipe. The sliding sleeve has a spring disposed therein, and two heads of the spring are pressed against the flange and the sliding sleeve respectively. | 01-21-2010 |

| 20130299006 | FAUCET CONTROL STRUCTURE - A faucet control structure includes an outlet head, a switch rod and a valve body. The outlet head is provided therein with a through-hole, a downward outlet end and an inlet chamber. The outlet end and the inlet chamber are separated by the through-hole. One end of the switch rod is enlarged to form a pulling head, and the other end is provided with a restricting groove. The valve body has a partitioning plate whose front surface is provided with two clamping claws. An inverted U-shaped flexible piece is integrally formed atop the valve body. Both sides of the flexible piece are provided with a bending section respectively. The bending sections provide a force for supporting the valve body when the valve body is compressed by an external force, and provide a restoring force to the valve body after the external force is removed. | 11-14-2013 |
