    Abstract: An apparatus is described for controlling a flow of a fluid therethrough while the apparatus is connected to a source of control fluid. The apparatus includes an input, a valve seat, a diaphragm, an output, and a diaphragm control space. The diaphragm control space is partially defined by the diaphragm, and includes a control fluid inlet and a control fluid outlet. The apparatus is operative to independently control a flow of control fluid into the diaphragm control space through the control fluid inlet and a flow of control fluid out of the diaphragm control space through the control fluid outlet. A deflection of the diaphragm in relation to the valve seat is responsive to a pressure of the control fluid in the diaphragm control space. The deflection of the diaphragm in relation to the valve seat is operative to control a fluidic flow resistance between the input and the output.

    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.

    Abstract: A pilot valve that includes a pilot valve body including a chamber, a first fluid inlet and a second fluid inlet for providing fluid to the chamber, and a fluid outlet for receiving fluid from the chamber. The pilot valve further includes a separating element and a valve rod, the valve rod is arranged to control fluid flow from the first or second fluid inlet to the fluid outlet via the chamber. The separating element is connected to, and movable with the valve rod, and has a first fluid contacting area configured to be in fluid communication with the first fluid inlet, and a second fluid contacting area configured to be in fluid communication with the second fluid inlet and arranged on an opposite side to the first fluid contacting area. The pilot valve is at least partly controlled by a difference between a first force and a second forces acting on the first and second fluid contacting areas of the separating element.

    Abstract: A servo valve includes a movable throttling member positioned between a first opening and an opposing second opening, and a first inlet port and a second inlet port to convey a fluid flow toward the first and opening, respectively. A first inlet orifice, defined between the first inlet port and a first pressure reaction member, is located between and in fluid communication with the first inlet port and the first opening. A second inlet orifice, is located between and in fluid communication with the second inlet port and the second opening. The second pressure reaction member is secured to the first pressure reaction member at a substantially fixed distance. Each of the first inlet orifice and the second inlet orifice is variable via a change a pressure of the fluid flow downstream of the first inlet orifice and the second inlet orifice.

    Abstract: Pilot valve structures are described as including a main valve having a main flow body and having an inlet and outlet, and a diaphragm, with a perimeter, a moveable portion, and first and second sides. A main flow orifice is located in the flow body between the inlet and outlet. A main valve plug is attached to and/or disposed in the moveable portion of the diaphragm and opens and closes the flow orifice when the moveable portion of the diaphragm is in first and second positions. The pilot valve also includes a pilot valve inlet that is connected to the flow path of the main flow body. A pilot valve outlet/orifice is disposed within and co-located with the main valve plug. The pilot valve includes a pilot valve plug, which is moveable to open and close the pilot valve orifice. Related mass flow controllers with such pilot valve structures are further described.
