  • Patent number: 10967733
    Abstract: A fuel shutoff valve includes a valve, a float, and an auxiliary member. The valve is configured to open or close an air passage of a fuel tank. The float floats on fuel and moves in a valve closing direction to close the valve, or in a valve opening direction opposite to the valve closing direction to open the valve. The auxiliary member has a predetermined weight, and abuts on the float to apply a weight on the float in the valve opening direction, or separating from the float not to apply the weight on the float in the valve closing direction.

  • Patent number: 10006555
    Abstract: Provided is a fluid flow valve including a housing including a fluid inlet port, and a fluid outlet port including an outlet aperture and a valve seating bounding the outlet aperture; a sealing-member configured to be biased, under fluid pressure within the housing, against the valve seating so as to seal the outlet aperture; a sealing-member displacing mechanism secured to the sealing-member so that displacement of the displacing mechanism in a first sense detaches the sealing-member from the valve seating so as to open the outlet aperture, while displacement of the displacing mechanism in an opposite sense allows for the sealing-member to become sealingly biased against the valve seating; and a sealing-member opening mechanism configured for displacing the sealing-member against the biasing effect of the displacing mechanism so as to discharge the fluid flow valve.

  • Patent number: 9999792
    Abstract: A dual air vent allows air or gas to be vented from a wet pipe fire protection sprinkler system, but inhibits water from spilling out. A conventional first air vent valve is operative to vent air or gas as a pipe is filled with water, but not vent the water. However, it may discharge a small amount of water when the pipe fills and substantially all air or gas has been vented. The output of the first air vent valve is not released into the protected premises, but rather is routed to a reservoir having a second air vent. Air or gas is vented through the second air vent, but any water discharged by the first air vent valve is retained in the reservoir. The reservoir is connected to the pipe by a one-way valve which allows air flow in either direction, and allows water flow from the reservoir to the pipe, but blocks water flow from the pipe to the reservoir. When the pipe is again drained, water retained in the reservoir is allowed to flow into the pipe, where it is also drained.

  • Patent number: 9845259
    Abstract: An apparatus for filtering water has a valve head and a filtration/purification canister removably mountable thereon. Connecting the canister to the valve head automatically opens a check valve in the valve head to permit water to flow from the valve head into and through the canister, and then back to and through the valve head to an outlet port. Disconnecting the canister from the valve head automatically closes the check valve, stopping the flow of water. A bypass valve is provided in the valve head to permit a sanitizing solution to flow through the valve head and along the lines of the water distribution system to sanitize the system, while bypassing the canister. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly from the outlet port to the appliance instead.
