Centrifugal gas-liquid separation and an outer-side oil return passage help a refrigeration ejector recover pressure without harming compressor durability.

Shared suction and motive lines simplify multi-ejector flow paths, cutting fluid losses while keeping compact, adjustable capacity.

A common suction and motive line lets multiple ejectors raise fluid capacity with simpler construction, lower losses, and controlled flow paths.

A movable needle varies ejector nozzle exit and throat areas to limit overexpansion loss and preserve refrigeration efficiency.

A cylindrical inline pump layout stabilizes vacuum generation while simplifying passages and enabling flexible use of universal ejectors.

A needle valve varies ejector throat and exit area to limit overexpansion, preserve refrigeration effect, and cut power consumption.

A semipermeable membrane separates hydrogen from water and nitrogen in fuel cell anode recirculation, improving gas purity and component protection.

An adjustable nozzle passage helps a fuel cell ejector sustain recycled hydrogen suction at low new-gas flow while keeping operation stable.

Electrodes and ion-selective membranes generate osmotic pressure to pump conductive solutions without moving parts, cutting maintenance and energy use.

Balanced pressure surfaces keep the second nozzle path open under jet pump pressure, stabilizing hydrogen recirculation in fuel cell conveyors.

Pressure-sensed inflation, venturi deflation, and emergency release cut mining tire service time while improving field safety.

Undercut inlets and deflecting walls create vortex-driven negative pressure to improve low-level operating medium withdrawal in tight vehicle packaging.

High hydrogen pressure actuates a recirculation blocking valve, cutting fuel cell loop cost while maintaining fresh hydrogen flow.

Multiple fixed nozzle geometries in one movable body improve hydrogen jet-pump recirculation across varying fuel flows without complex valves.

A quick-closure line block disconnects all supply air lines at once, speeding powder injector cleaning and color changes while reducing contamination risk.

A snap-coupled line block disconnects air lines and the powder hose together, speeding injector cleaning and color changes.

A confuser-constriction-diffuser charging inlet raises pump inlet pressure, cuts cavitation risk, and improves oil charging at high speed.

Multiple feed orifices and adjustable distribution ducts stabilize low-speed Coanda gas flow, reducing turbulence and protecting fragile materials.

A rotatable elbow joint lets a water-powered sump pump fit vertical or horizontal layouts while maintaining a secure, leak-resistant connection.

Separate molded suction and mixing parts with translational and rotational locking simplify ejector assembly while maintaining durable vacuum generation.
