Abstract
A gas delivery augmenter may include a pump mechanism for facilitating inflation of an inflatable. The pump mechanism is generally configured to be driven/powered by pressure-volume energy from a primary gas received by the gas delivery augmenter, and the pump mechanism of the gas delivery augmenter is configured to entrain a secondary gas deliver the entrained secondary gas (and any remaining primary gas) to the inflatable. The pump mechanism, as described in greater detail below, enables secondary gas to be pumped/delivered to the inflatable even as the inflatable backpressure increases, thus providing improved inflation over conventional aspirators.
Claims20
A gas delivery augmenter comprising a pump mechanism, wherein the gas delivery augmenter is configured to receive a primary gas from a gas supply, wherein reception of the primary gas is configured to drive the pump mechanism using pressure-volume energy from the primary gas to entrain a secondary gas and pump at least a portion of the primary gas and the secondary gas to an inflatable.
An inflation system comprising:
- a gas supply configured to provide a primary gas;
- and
- a gas delivery augmenter coupled to the gas supply and comprising a pump mechanism, wherein the gas delivery augmenter is configured to receive the primary gas from the gas supply, wherein in response to reception of the primary gas, the gas delivery augmenter is configured to drive the pump mechanism using pressure-volume energy from the primary gas to entrain a secondary gas and to pump at least a portion of the primary gas and the secondary gas to an inflatable.
An evacuation assembly of an aircraft, the evacuation assembly comprising:
- an inflatable slide;
- a gas supply configured to provide a primary gas;
- and
- a gas delivery augmenter coupled to the gas supply and comprising a pump mechanism, wherein the gas delivery augmenter is configured to receive the primary gas from the gas supply, wherein in response to reception of the primary gas the gas delivery augmenter is configured to drive the pump mechanism using pressure-volume energy from the primary gas to entrain a secondary gas and to pump at least a portion of the primary gas and the secondary gas to the inflatable slide.
