Valves With Separate, Correlated, Actuators Patents (Class 137/637)
  • Patent number: 9612019
    Abstract: A safety system for gas-operated cooking appliances which include at least one burner which is connected to the mains gas network via a distributor, the gas flow of which is controlled by a manually operated gas tap, includes a position switch, a flame detection device, an electrically controlled control valve which is installed in the mains gas network, a manually actuated restoring switch in operable communication with the control valve, and a control circuit. The control circuit is configured to open the control valve after the latter was shut off by the flame detector of the burner only when the control circuit simultaneously receives a signal from the restoring switch and the position switch. The safety system serves as a child safety measure which prevents an inadvertent re-activation of a gas flow system that has been shut off.

    Abstract: Embodiments relate to valves comprising a member such as a plate or poppet, that is moveable relative to a stationary seat. The state of the member may be maintained against opposing forces with relatively little expenditure of energy. According to one embodiment, a poppet displaced from seating in the valve seat, may be held in position against opposing forces tending to close the valve, until a desired flow of gas through the valve has taken place. The poppet may then be released as desired, such that those opposing forces serve to passively close the valve. The valve may be secured in position utilizing mechanical, magnetic, electromagnetic, pneumatic, electrostatic, or hydraulic approaches. Valve embodiments may be particularly suited to controlling gas flows for compression and/or expansion in an energy storage system.

  • Publication number: 20120137688
    Abstract: A valve device incorporating two valves is provided. For example the two valves could be a stop valve and a control valve, housed in the same side of a common casing. The proposed valve device includes an inlet port and an outlet port connected by a fluid flow channel. The valve device further includes a first valve and a second valve housed in a common casing. The first valve includes a first valve head mounted on an annular-shaped first spindle. The second valve includes a second valve head mounted on a second spindle, the second spindle extending concentrically and slidably through the annular-shaped first spindle. The first and second valves are displaceable along a common axis and operable to influence fluid flow between the inlet port and the outlet port through the flow channel.

    Abstract: Disclosed is a work vehicle having a hydraulic apparatus which can reliably prevent erroneous operation of the valve of the hydraulic apparatus even when the operating lever is moved inadvertently. With this hydraulic apparatus, with operations of a single operating lever in two directions, two valves are operated respectively. Two valve operating links for operating the two valves respectively are pivotally supported to a support shaft provided to a pair of frame plates and a lock pin is provided to the frame plates. The two valve operating links form pin holes. When the two valves are at the neutral positions, the lock pin is inserted into the pin holes with a locking operation of a lock operating tool, thus fixing the valve operating links and locking the valves.
