摘要： The subject invention is a valve for regulating the viscosity of fluid. The valve includes a housing defining a bore having a first inlet supplying “cold” hydraulic fluid at a first viscosity and a second inlet supplying “hot” hydraulic fluid at a second viscosity. A spool valve disposed within the bore has at least one land to proportionally control the flow of hydraulic fluid through the inlets. Hydraulic fluid from the first and second inlets mixes within the valve and exits the valve through an outlet at an optimum viscosity. A flow restrictor creates a pressure force on the spool valve that is proportional to the viscosity of the hydraulic fluid flowing through the outlet. The pressure force acts to move the spool valve such that the spool valve partially blocks the flow of hydraulic fluid through the first and second inlets, thereby controlling the proportion of “cold” and “hot” fluid to maintain the viscosity of the hydraulic fluid flowing through the outlet.

摘要： A fuel supply system for a gas turbine engine has a first pump for delivering fuel to a first use on a gas turbine engine, and a second pump for delivering fuel to a second use on the gas turbine engine. A valve allows flow from the first pump to be delivered to the first use, but also routes some flow from the first pump to supplement fuel flow from the second pump until a pressure downstream of the second pump increases. The valve then allows flow from the second pump to flow to the first use to supplement the flow from the first pump.

摘要： A fuel control system independently meters fuel flow to a first and a second set of pilot fuel nozzles, and to a set of main fuel nozzles. A pilot coaxial metering and pressure regulating valve is coupled between a primary fuel inlet line and the first and second sets of pilot nozzles, and a main coaxial metering and pressure regulating valve is coupled between the primary fuel inlet line and the set of main fuel nozzles. Each coaxial metering and pressure regulating valve maintains a substantially constant pressure drop across the respective valve, and includes a metering window. The size of each metering window is controlled by an engine electronic control unit based on the signals transmitted by a respective LVDT, in order to precisely meter the fuel flow through the valve and to the respective sets of fuel nozzles. A control pressure regulating valve maintains a minimum pressure differential between the fuel inlet line and the downstream sides of the coaxial metering and pressure regulating valves, in order to provide sufficient pressure to operate the valves, and directs excess fuel from the fuel pump into a return line. A minimum pressure and shut-off valve is coupled between each coaxial metering and pressure regulating valve and the respective fuel nozzles, in order to maintain a minimum fuel pressure level, and to terminate fuel flow to the nozzles. A sequence valve is coupled to the minimum pressure and shut-off valves to control actuation of the valves.

摘要： A method and system for providing fuel to primary and secondary fuel nozzles in a gas turbine engine fuel system comprises generating a fuel flow and routing primary fuel from the fuel flow to a primary fuel nozzle. Backpressure on the fuel flow is maintained using a valve. The valve is opened at increased fuel flow to route secondary fuel from the fuel flow to a secondary fuel nozzle. The valve is progressively opened under increasing fuel flows to reduce a pressure drop across the valve produced by the secondary fuel.
