Abstract
A control valve includes a slide valve having a slide movable within a channel between a first position and a second position. When the slide is in the second position, the channel is arranged in fluid communication with an outlet line. A pressure regulator is arranged upstream from and in fluid communication with the slide valve and is operably coupled to a fluid source. The pressure regulator includes a flow metering element movable between an open position and a closed position to regulate a flow of fluid and pressure through the control valve in response to a pressure variations within the downstream slide valve.
Claims18
A control valve, comprising:
- a slide valve including a slide movable within a channel between a first position and a second position, wherein when the slide is in the second position, the channel is arranged in fluid communication with an outlet line, the slide configured for movement from the first position to the second position by fluid pressure in the channel;
- a pressure regulator arranged upstream from and in fluid communication with the slide valve and operably coupled to a pressure vessel of pressurized inflation gas, the pressure regulator including a flow metering element movable between an open position and a closed position to regulate a flow of fluid and pressure through the control valve in response to a pressure variations within the downstream slide valve;
- wherein when the flow metering element is in the opened position pressurized inflation gas is directed from the pressure vessel, through the pressure regulator and to the slide valve;
- and
- wherein when the slide valve is in the second position the pressurized inflation gas flows from the slide valve into the outlet line for inflation of an inflatable evacuation slide.
An aircraft evacuation slide inflation system, comprising:
- an inflatable evacuation slide stored in an undeployed position;
- a source of inflation gas for inflating said inflatable evacuation slide;
- and
- a control valve including:
- a slide valve including a slide movable within a channel between a first position and a second position, wherein when the slide is in the second position, the channel is arranged in fluid communication with an outlet line, the slide configured for movement from the first position to the second position by fluid pressure in the channel;
- a pressure regulator arranged upstream from in fluid communication with the slide valve and operably coupled to the source of inflation gas, the pressure regulator including a flow metering element movable between an open position and a closed position to regulate a flow of fluid and pressure through the control valve in response to a pressure variations within the downstream slide valve;
- wherein when the flow metering element is in the opened position, pressurized inflation gas is directed from the pressure vessel, through the pressure regulator and to the slide valve;
- and
- wherein when the slide valve in the second position the pressurized inflation gas flows from the slide valve into the outlet line for inflation of an inflatable evacuation slide.
