A method of making an additively manufactured ejector pump includes creating a computer file defining the ejector pump in layers. The ejector pump includes a duct extending along a centerline from an upstream end to a downstream end, a nozzle extending inward from the duct including a flowpath, an annulus connected to the duct including a cavity. The method also includes building the ejector pump using an additive manufacturing process that builds the ejector on a layer-by-layer basis from the upstream end to the downstream end.

A blower/fan for the purpose of greatly reducing noise levels and extending longevity over conventional blade-based blower/fans (e.g., 50 decibel leaf-blower), due to having a totally novel absence of moving parts, such as motor and blades, which create most of the noise and wear out faster. The air motivating force comes from an electrohydrodynamic ionic wind created by a very strong electric field crossing two uniquely configured electrodes. This wind is then further amplified by inducing outside air to be added to this wind by means of a Coand surface at the entrance to the wind tunnel and which then feeds over a slit. A diffuser section follows causing the wind pressure to build for improving the exiting air characteristics. The novel diffuser and Coand surfaces will have reduced drag and noise due to both a low friction surface coating and a dimpled surface like a golf ball so as to further reduce drag.

Provided herein are articles of manufacture, systems, and methods employing a gas-deflector plate in low to ultra-high vacuum systems that use differential pumping (e.g., gas-target particle accelerators, mass spectrometers, and windowless delivery ports). In certain embodiments, the gas-deflector plate is configured to be positioned between higher and lower pressure regions in a pressurized system, wherein the gas-deflector plate has a channel therethrough shaped and/or angled such that jetting gas moving through the channel enters the lower pressure region at an angle offset from the vertical axis of the gas-deflector plate and/or the channel. In other embodiments, a jet-deflector component is employed such that the jetting gas strikes such jet-deflector component and is re-directed in another direction.

A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.
