  • Patent number: 10287968
    Abstract: An engine cooling system includes a coolant circuit, a multi-way valve, a relief route and a relief valve. The coolant circuit includes a first route and a second route into which the coolant circuit is branched off at a branched position. The first route passes through a radiator. The multi-way valve is provided at the branched position. The relief route sets a relief source to a portion downstream of a pump and upstream of the multi-way valve in the coolant circuit, sets a relief destination to a portion downstream of the radiator in the first route, and causes coolant to flow from the relief source to the relief destination so as to bypass the multi-way valve. The relief valve interrupts circulation of coolant through the relief route when the relief valve is closed, and permits circulation of coolant through the relief route when the relief valve is open.

  • Patent number: 9850644
    Abstract: A plunger-type diaphragm valve is disposed in an accommodation trough of a flush device. The accommodation trough communicates with an inlet passage and an outlet passage. The valve includes a control unit. One end of the control unit is provided with a diaphragm member and an engaging member, and another end leans against the outlet passage to block the inlet passage and the outlet passage. An outer wall of the diaphragm member is fixed to the accommodation trough. The diaphragm member has a curved portion. When the valve is actuated, the curved portion is deformed by water pressure to bring the control unit to move away from the inlet passage for the inlet passage to communicate with the outlet passage. The stressed area of the diaphragm member is small and the deformation is less, so the diaphragm member won't wear. The valve is durable and has a long life.

  • Patent number: 8496021
    Abstract: An aircraft includes an overpressure valve with a sealing member which is moveable, in response to a first pressure differential across the valve, between a closed position and an open position. The overpressure valve further has a frangible portion, for example, a carbon or sheet metal disc. The frangible portion is arranged to fail in response to a second pressure differential across the valve, the second pressure differential being more than the first pressure differential. Thus the valve is still able to relieve pressure when the sealing member is jammed (due to ice, for example). The valve may be in the surge tank of a fuel tank system.

  • Patent number: 6745794
    Abstract: A valve assembly in which a primary valve is provided within a primary passageway of a valve housing to control flow rates of a fluid flow within the primary passageway. The primary valve is moved between open and closed positions relative to a valve seat defined in the primary passageway to produce higher flow rates as the primary valve is moved towards the open position and lower flow rates as the primary valve is moved towards the closed position. As the primary valve is moved towards the closed position an ever increasing flow rate occurs within a secondary passageway formed in the primary valve by at least an orifice. A secondary needle valve, projecting into the orifice, meters such ever increasing flow rate and thereby the lower flow rates of the fluid flow. The secondary needle valve can be attached to the valve housing and thus, be fixed in position or can be attached to a valve steam to control the degree to which the secondary needle valve projects into the orifice.
