The present disclosure is directed to a fluid separating flow nozzle which has a diffuser housing configured to be secured to a source of compressed fluid, and a diffuser element secured within a portion of the diffuser housing. The diffuser element may have at least one flow path opening forming a flow path through the flow nozzle, a nose portion and a moisture capturing area adjacent the nose portion for capturing moisture particles when a first airflow is directed through the flow nozzle in a first direction. A flow turning element may be incorporated which has a plurality of flow turning structures, and which is in communication with the flow path opening, and which imparts a turning motion to the first airflow and also to a second airflow flowing in a direction opposite to the first airflow. The turning motion helps to displace and eject moisture particles from the nose portion and from the moisture capturing area while the second airflow is occurring.

An aspirator assembly for an inflatable device includes an outer housing disposed about an axis, an inner housing disposed about the axis, and a manifold coupled through the outer housing to an annulus located between the inner housing and the outer housing, the manifold providing pressurized gas to said annulus via a plurality of gas ejector nozzles. The annulus may be divided into a plurality of annulus segments by a plurality of vanes protruding radially from the inner housing.

A centrifugal gas compressor with rotating hollow housing and an independently rotating, turbine compresses gas bubbles in capillary tubes and recovers energy from the liquid drain (sometimes a liquid recycler). The housing rotatably retains an internal spool having the turbine. Gas-liquid emulsion fed to the capillaries generates compressed gas-liquid emulsion at a radially distal annular region in an annular lake within the spool. Compressed gas leaves the lake and is ported away. A turbine blade edge in spilt over liquid drives the turbine, converting angular velocity/momentum into shaft torque as recovered energy. Blade captured liquid is recycled to capillary inputs.

A propeller-less unmanned aerial vehicle having a body having a plurality of channels, an inlet formed in the body and configured to allow air flow to enter the plurality of channels from an exterior of the body, an anechoic chamber formed in the body and coupled to the plurality of channels, a rotor comprising a plurality of angled fins located in the anechoic chamber, a control system configured to direct air flow within the plurality of channels, and one or more circular tubes coupled to the exterior of the body and in communication with the plurality of channels. The air flows into the body through the inlet, into the plurality of channels and the anechoic chamber, and exits through the one or more circular tubes to provide lift and directional control to the propeller-less unmanned aerial vehicle.

The present invention relates to an ejector assembly and a vacuum pump, the ejector assembly including a typical cylindrical vacuum ejector and a support part. The support part includes a first support having a supply line extending outwards from a hole in which a first end of the ejector is mounted, and a second support having a discharge line extending outwards from a hole in which a second end of the ejector is mounted. Further, the first and second supports facing each other are configured such that the outer circumferential surfaces thereof are in contact with the inner circumferential surface of a pipe member so as to form a space between the first and second supports, the space communicating with through holes. In the vacuum pump using the ejector assembly, the pipe member is a housing, and the space is a vacuum chamber formed in the housing.
