摘要： A pressure regulator system is disclosed. The system includes: a valve module; a controller; and a plurality of sensors. The controller is operably coupled to the valve module to adjust outflow of gas from an outlet of the valve module to a plurality of masks in an interior of an aircraft. The plurality of sensors comprises at least one of a pressure sensor and a temperature sensor and the controller is configured to receive feedback of sensed data at the outlet of the valve module about at least outlet pressure and ambient temperature from at least the pressure sensor and the temperature sensor and adjust the outflow of gas from the outlet of the valve module by determining an open-valve time based on the feedback of sensed data received from each sensor.

摘要： A brake system for actuating a pair of front wheel brakes and a pair of rear wheel brakes includes a reservoir and a deceleration signal transmitter. First and second power transmission units are configured for selectively providing pressurized hydraulic fluid during a braking event. The first power transmission unit actuates a selected one of the front wheel brakes and a selected one of the rear wheel brakes. The second power transmission unit actuates the other one of the front wheel brakes and the other one of the rear wheel brakes. First and second electronic control units control the first and second power transmission units. A pair of rear brake motors selectively electrically actuate rear wheel brakes. Multiplex control of each of the pairs of front and rear wheel brakes is provided by an arrangement of first and second parallel valves for each wheel brake.

摘要： A control system may include a recirculation circuit configured to direct fluid from an outlet of a fluid pump, via a first portion of the recirculation circuit, to an inlet of the fluid pump via a second portion of the recirculation circuit. The control system may include a control valve in the recirculation circuit between the first portion and the second portion. The control system may include a check valve downstream of the first portion. The control system may include a controller configured to cause a pulse of the control valve that opens the control valve for a time interval and closes the control valve, and to transmit a signal to indicate that the check valve allows reverse flow of the fluid based on a pressure, in the time interval, of the fluid in the first portion being indicative of the check valve allowing reverse flow of the fluid.

摘要： A dual-chamber pressure control method and a dual-chamber pressure control device are described. The dual-chamber pressure control method uses a stepped pressure adjustment to ensure that the pressure adjustment at each stage will not exceed a safe value of an internal chamber body. The dual-chamber pressure control device includes a dual-chamber member, an external chamber pressure control module, and an internal chamber pressure control module. The external chamber pressure control module is used to adjust an external chamber pressure of the dual-chamber member, such that an external chamber pressure value changes with time to show a stepped external chamber pressure adjustment line. The internal chamber pressure control module is used to adjust an internal chamber pressure of the dual-chamber member, such that an internal chamber pressure value changes with time to show a stepped internal chamber pressure adjustment line.

摘要： A pressure fluid handling system includes a closed pressure fluid circuit. The pressure fluid circuit includes, connected in series, a compressor and a pressure sink and a primary pressure fluid route from the compressor to the pressure sink and a secondary pressure fluid route from the pressure sink to the compressor. The pressure fluid handling system further includes a pressure fluid accumulator connected to the pressure fluid circuit via a first pressure fluid accumulator conduit. The first pressure fluid accumulator conduit includes a pump configured to pump pressure fluid from the pressure fluid circuit to the pressure fluid accumulator to lower the pressure levels in the pressure fluid circuit, and in that the pressure fluid handling system includes a controllable component for returning the pressure fluid from the pressure fluid accumulator to the pressure fluid circuit to increase the pressure levels in the pressure fluid circuit.
