Abstract: An exemplary embodiment of the invention is directed to a fuel flow control system for use with a fuel distribution system having a plurality of zones each including a servovalve. The fuel flow control system includes a fluidic multiplexer having a plurality of pressure ports and a plurality of servoflow ports. The fluidic multiplexer sequentially receives pressure from each zone and sequentially provides servo fluid to each servovalve. A pressure sensor is fluidly coupled to the pressure ports and generates a pressure signal for each zone. A controller receives the pressure signal and generates a control signal. A driver receives the control signal and increases or decreases flow through the servoflow ports in response to the control signal.

Abstract: The pressure of hydraulic fluid which is supplied to the continuously variable transmission in the power train of a motor vehicle is regulated by an apparatus wherein an adjustable pilot valve can receive fluid from a pilot conduit leading to a pressure reducing valve. The pilot conduit normally receives fluid from a further conduit, wherein the pressure of fluid is at least substantially constant, by way of a flow restrictor. A branch conduit serves to evacuate fluid from the pilot conduit into the pilot valve when the latter is at least partially open. The fluid-discharging end of the flow restrictor confronts the inlet of the branch conduit, and such inlet is narrowed to reduce the likelihood of turbulence developing in the fluid stream flowing from the pilot conduit, across the further conduit and into the inlet of the pilot valve.

Abstract: A pressure balanced valve assembly for mixing hot water and cold water includes a body with two inlets which communicates with two respective outlets in the body, a flexible balanced member securely located between the two pairs of the inlet and the outlet. Two side members are engaged with the two inlets and each of the side members has a plurality of L-shaped inlet paths in the outside thereof and a chamber in the inside thereof, wherein the inlet paths communicate with the corresponding chamber. Two rods each have one end thereof connected to the two sides of the balanced member and the other end thereof removably received in the chamber and engagable with the inner periphery of the inlet corresponding thereto. The water entering from the inlets of the body will not impact the balanced member directly which is therefore operated precisely.

Abstract: Disclosed is a gas inlet device comprising a gas reservoir (5), which is connected via a supply line (11) via a supply flow restrictor (10) which can be closed by a supply valve 13). The gas can be supplied into the antechamber (5) via a control valve (6) and a control flow restrictor (4). As the control valve (6) and the supply valve (13) close the antechamber from the outside, there are only minimal fluctuations in pressure during switching. By this means the pressure in the antechamber (5) can be controlled precisely and the gas flow from the antechamber (5) into the supply line (11) can be set with great precision.
