  • Patent number: 9938656
    Abstract: Dryer appliances and methods for operating dryer appliances are provided. A method includes flowing internal air from a drum chamber through an outlet assembly of the dryer appliance, and selectively actuating a valve to flow external air to the outlet assembly of the dryer appliance from external to a cabinet of the dryer appliance. The method further includes alternately sensing open flow pressure values of the external air being flowed to the outlet assembly from external to the cabinet when the valve is open and closed flow pressure values of the external air being flowed to the outlet assembly from external to the cabinet when the valve is closed.

  • Patent number: 9581258
    Abstract: Check valves are disclosed, including check valve included in an aspirator, that includes a housing defining an internal cavity having a first port and a second port both in fluid communication therewith, and a sealing member within the cavity. The sealing member is translatable between a closed position against a first seat within the internal cavity of the housing and an open position against a second seat within the internal cavity of the housing. The sealing member has a sealing material positioned for sealing engagement with the first seat when the sealing member is in the closed position and a reinforcing member positioned for engagement with the second seat when the sealing member is in the open position.

  • Patent number: 7334599
    Abstract: A single lever faucet with spray, wherein two cold and hot water inlet holes, a water outlet hole and a through hole are defined in the bottom of the faucet body, and the water outlet hole is connected to a hollow threaded tube, and the through hole is connected to a connecting tube. One side of the peripheral of the faucet body is defined with a chamber and a controlling device, and in the top surface of the faucet body is formed an inserting groove that is connected to the through hole for inserting a discharging base. A tee joint member is mounted between the hollow threaded tube and the connecting tube, a valve room is defined in the tee joint member for installing a diverter valve, and the middle section of the tee joint member is connected to the hollow threaded tube, and the ends are connected to a spray gun and a guiding tube respectively. Therefore, by opening and closing the spray gun, the water that supplied to the spray gun and the water outlet tube can be changed automatically.

  • Patent number: 6422834
    Abstract: A valve arrangement including a valve housing (10) which includes an inlet port (11) and two outlet ports (12, 13) for fluid flowing through the housing. A valve element (15) is accommodated in a first valve space in the valve housing and movable between two end positions. The valve element includes two surfaces (16), each of which is adapted for co-action with a respective outlet port such as to close an associated outlet port in one and the other of the end positions of the valve element (15). A device (20 or 21 and 26, 47) for resetting the valve element between the positions. The valve element (15) is mounted on one end of a pivotal arm (18) and has the form of a valve plate or disc which includes valve-element surfaces (16) for alternate co-action with a respective outlet port (12, 13).

  • Patent number: 6419463
    Abstract: A valve housing (10) includes an inlet port (11) and two outlet ports (12, 13) for fluid passing through the housing. A valve element (15) accommodated in the valve housing is moveable freely between two end positions and has two surfaces (16) each adapted to close a respective outlet port in one and the other of the two end positions of the valve element. The valve element further includes members (20, 22: 21, 22: 21, 26, 47; 26, 48; 26, 50; 26, 51-54) for resetting between the positions. A double-action pump includes two spaces or rooms that have valve-controlled inlets and outlets (39, 40; 29, 30) for drive fluid and pump-transported working fluid respectively. The spaces are divided into an operating chamber (28) and a working chamber (27) by partition walls (26, 36, 37) which are pistons or diaphragms (26) and reciprocatingly move between end positions.
