  • Patent number: 8413951
    Abstract: A valve device includes a temperature sensor disposed to project from a housing to a tank inner space to detect the temperature in the tank inner space, and can detect the temperature without being influenced by the heat capacity of the housing. A coil generates a magnetic force to drive a valve with three terminals arranged at different positions in an axial direction, and a drive voltage is selectively applied between two of the terminals. A current value of the driving current which energizes the coil can be changed by selecting the terminals between which the drive voltage is applied. Without controlling the drive voltage, it is possible to suppress wasting power such that the driving current of the large current value is generated in the start-up time, and the current value of the driving current is decreased in the holding time.

  • Publication number: 20120180778
    Abstract: The present disclosure is directed to a mobile machine, such as hydronic surface heater designed to be transported to a potentially remote worksite and operated for an extended period of time. The machine has a fueled component, such as a burner, fueled by a fuel supply system having at least two fuel tanks that are operably connected to one another by a connection line having an electronically controlled valve therein. The valve is coupled to the machine's electrical system, such as being coupled to the output of the machine's main breaker, so as to be opened whenever the machine is operating but to be otherwise closed. The fuel supply system thus has, in effect, a single tank when the machine is running and multiple separated tanks when the machine is not running. Fuel spill risks therefore are mitigated without having to sacrifice operating time and without significantly complicating the machine's fuel supply systems or its controls.

The electromagnetic valve includes a valve core including a plurality of orifices for a passage of fluid therethrough; a directional housing enclosing the valve core and enabling a controllable, lateral movement of the valve core from a closed position to an open position; a plurality of seals positioned within the directional housing to prevent leakage of the fluid; and a plurality of magnet cores attached adjacent to the directional housing, each magnet core including a wire winding for generating an electromagnetic field when actuated by means of an electrical current. When the generated electromagnetic field is applied to a first magnet core, the valve core slides laterally into the first magnet core to an open position enabling the flow of water through the orifices and an opening of the directional housing.

  • Publication number: 20100051843
    Abstract: Precise control over gas delivery is achieved at the micro and nanobar mass levels by incorporating blocks of aligned carbon nanotubes into valves and finely adjusting the flow through the block by controlling a compressing force applied to the block. A valve for controlling gas flow includes: a valve housing; a block of aligned carbon nanotubes, the block and the valve housing being configured to direct the gas through the carbon nanotubes in the block; and a device configured to apply a force to the block in order to compress the block, wherein the block is compressed perpendicular to the walls of the carbon nanotubes in the block; whereby the application of the force to the walls restricts the flow of the gas through the valve. The valve may further comprise an electrical device for monitoring the electrical properties of the carbon nanotube block. This monitoring provides information on the state of compression of the carbon nanotube block and/or the gas that is flowing through the valve.

  • Publication number: 20090140186
    Abstract: A solenoid actuator includes an electrical circuit with a first power input terminal, a second power input terminal, a first coil wound around a first axis and configured to generate a first magnetic field while electrical current flows through the first coil, and a second coil wound around a second axis configured to generate a second magnetic field while electrical current flows through the second coil. An electric switch connects or disconnects the first coil and second coil in series. Thus, the electric switch can energize or de-energize the second coil. A movable member, such as a rod, bar, spool, or hollow tube, influenced by the magnetic fields generated by the first and second coils is configured to move with respect to the first and second coils from a first position to a second position in response to the magnetic field generated by the first coil.

  • Patent number: 7527072
    Abstract: A gas cook-top with glass (capacitive) touch controls and automatic burner re-ignition is provided. The gas cook-top utilizes a variable flow gas control valve that is driven by an electronic controller whose user interface provides a glass capacitive touch interface. Various electronic features including safety lockouts and burner re-ignition are provided, as is relational control of the burner flame. As a user moves their finger along a flame adjust indicator, the electronic control positions the variable flow gas valve to control the flame height of the burner to correspond to the relative position along the indicator selected by the user.

    Abstract: An electromagnetically driven valve operated by electromagnetic force includes a stem, a driven valve, a swing member, and a first and second electromagnet. The first electromagnet and the second electromagnet include: a first and second core made of magnetic material, respectively; and a first and second coil, respectively, which are wound around the first core and the second core, respectively. The first coil and the second coil have the same number of turns, and are connected with each other. A magnetic path width of the second core is larger than a magnetic path width of the first core. When the swing member is located at a neutral position at which the swing member is in contact with neither the first electromagnet nor the second electromagnet, the distance between the second core and the swing member is smaller than the distance between the first core and the swing member.
