  • Patent number: 12044325
    Abstract: In the present disclosure, A cold waterway, a hot waterway and a mixing waterway and a main body are formed integrally in a valve structure, and a faucet structure has the valve structure, a valve core and a handle cover. The cold waterway, the hot waterway and the mixing waterway are formed in the main body by drilling the main body, such that the above three waterways and the main body are formed integrally. Then, an outlet is disposed to be connected to an annular waterway surrounding the main body, and the annular waterway outputs water to the outlet. Thus, it effectively solves the problems of water seepage caused by the tolerance between components or the long-term use of the valve core, and achieves the main advantages of effectively saving water by avoiding water seepage, and eliminating the need for gaskets to avoid poor sealing after aging.

  • Patent number: 11982376
    Abstract: Disclosed embodiments include ball valves with an asymmetric seal and seat, to minimize seal wear. In embodiments, a seal is disposed upon a ball with a first and second section, where the first section of the seal is disposed at a different angle from the second section. A seat has a first and second section at different angles that correspond to angles of the first and second section of the seal, respectively, such that the seal fully contacts the seat when the ball is in a closed position. When the ball is rotated to an open position, the different angles of the first and second sections allow the second section of the seal to clear the first section of the seat without contact.

  • Patent number: 11976746
    Abstract: A fail-safe actuator for moving a part has in each case a drive (18, 118) by means of which a first or a second drive train (24, 26) can be moved. The drive trains (24, 26) in each case have their own output shaft (34, 38) and can be actuated independently of one another. An energy storage device is coupled with the second output shaft (38), wherein a holding device selectively holds the energy or releases it from the energy storage device, so that the second output shaft (38) can be moved. A rotary entrainment of the first output shaft (34) ensures that in the event of a failure of the drive (18) this is moved into a specified end position. The two output shafts (34, 38) are set in motion via gear wheels (32, 36) if the drive trains are actuated. An assembly unit consisting of actuator and moved part is also described.
