| 20160090720 | Two-Path Water Output Device - A two-path water output device includes a valve, and is mounted around by a shell. The valve has a first waterway and a second waterway. The first waterway is constantly connected to a water converter, while the second waterway is controlled to be open or closed by a control valve core. Such two-path structure is simple, novel and easily controllable for two types of water output like tap water and filtered water. When the second waterway is closed, the water pressure switches a water converter connected to the inlet end of the valve to the first waterway to output water. When the second waterway is open, the released pressure switches to the first waterway to output water. | 03-31-2016 |
| 20160091101 | Pressure Reducing Valve with Separate Radial Bores for Different Fluid Flow Paths - A hydraulic cartridge valve includes a sleeve with a longitudinal bore that forms a working port via an end opening. A plunger is accommodated for linear motion in the longitudinal bore. The sleeve is penetrated in an inlet port region by a first radial bore that extends radially with respect to a longitudinal axis of the hydraulic cartridge valve. The sleeve is penetrated in a return port region by a second radial bore that extends radially with respect to the longitudinal axis. A first fluid flow path extends from the inlet port to the working port and a second fluid flow path extends from the working port to the return port. The plunger has third and fourth radial bores that extend radially with respect to the longitudinal axis and form part of the first and second fluid flow paths, respectively. | 03-31-2016 |
| 20160186882 | LOW POWER SOLENOID ACTUATED VALVE - A solenoid valve has a housing defining a first axis and second axis, a solenoid which produces a magnetic field along the first axis, a valve shaft movable between open and closed positions along the second axis, and a manifold mounted to the housing. The axis is biased toward the closed position by a spring and mechanical forces sufficient to overcome the force of the spring are transferred from the solenoid to the shaft by a lever to open the valve and then hold the valve open. A poppet seal, which interacts with a portion of the housing to close the valve, and a spool seal, which interacts with portions of the manifold to route fluid to the desired port, are mounted to the shaft. An electronic circuit controls delivery of current to the solenoid to shift and hold the shaft in the open position. | 06-30-2016 |
