摘要： A shut-off valve system includes a tank having an inlet and an outlet with a flow path defined therebetween. A float within the tank occludes the tank outlet at a first fluid level under positive G forces and unoccludes the tank outlet at a second fluid level under positive G forces. A flow restricting orifice and/or a hydraulic fuse is downstream of float and tank outlet to restrict fluid communication between tank outlet and an ejector pump. A method for restricting flow in an ecology fuel return system includes recovering fuel from engine components, communicating the fuel to an inlet of a fuel tank, pumping the fuel from an outlet of fuel tank to an inlet of an engine when a float within tank unoccludes the outlet of the fuel tank, and restricting fluid flow from tank outlet to an ejector pump with a flow restricting orifice and/or a hydraulic fuse.

摘要： A fuel supplying system includes a primary circuit for delivering fuel from a fuel tank to a primary circuit outlet. The system also includes a first supply circuit connected to the primary circuit outlet, the first supply circuit comprising a first supply circuit pump configured to pump fuel from the primary circuit outlet to engine fuel nozzles. The system further includes a second supply circuit also connected to the primary circuit outlet. The second supply circuit includes at least one actuating device configured to receive power from hydraulic pressure of the fuel. The second supply circuit also includes a second supply circuit pump configured to pump fuel from the primary circuit outlet to an actuating device, wherein the second supply circuit pump is independent from the first supply circuit pump. The second supply circuit further includes a return circuit configured to return fuel from the actuating device to the second supply circuit between the primary circuit outlet and the second supply circuit pump.

摘要： An electrical chassis for use in high temperature environments is disclosed. The electrical chassis may be employed, for example, in close proximity to the combustion chamber of a jet engine. The electrical chassis is constructed with a substrate formed from a material with low thermal conductivity and low electrical conductivity, such as polyetheretherketone. A reflective surface may be disposed on a housing containing the substrate to reduce the absorption of radiation. A heat sink and fluid inlet and outlet may also be arranged to remove heat generated by the electrical components.

摘要： A starter air valve has a valve member and an actuator. A rotary spool valve has a rotatable valve body and an outer housing to selectively provide three modes of operation for the starter air valve. A first mode of operation connects air through the rotatable valve body to communicate with an actuator control, and to receive air back from the actuator control. The rotatable valve body then communicates the air to the actuator. In a second mode the rotatable valve body blocks communication between the actuator control and the actuator, and delivers air through a variable area port in a wall of the rotatable valve body to bypass the valve member. In a third mode the rotatable valve body blocks communication between the actuator and the actuator control, and connects air to the actuator without having passed to the actuator control. A starter air system is also disclosed.

摘要： A starter air valve (SAV) system can include a pressure actuated SAV actuator configured to be operatively connected to a SAV and a first pressure valve configured to selectively allow pressure from a pressure source to the SAV actuator when in fluid communication with the SAV actuator. The first pressure valve can be a pulse-width modulation solenoid valve configured to provide a duty cycle of pressure from the pressure source to the SAV actuator.
