2. Vacuum ejector - Wikipedia

   en.wikipedia.org/wiki/Vacuum_Ejector

   A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.

3. Injector - Wikipedia

   en.wikipedia.org/wiki/Injector

   It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow. Depending on the application, an injector can also take the form of an eductor-jet pump, a water eductor or an aspirator. An ejector operates on similar principles to create a vacuum feed connection for braking systems etc.

4. Diffusion pump - Wikipedia

   en.wikipedia.org/wiki/Diffusion_pump

   The steam ejector is a popular form of pump for vacuum distillation and freeze-drying. A jet of steam entrains the vapour that must be removed from the vacuum chamber. Steam ejectors can have single or multiple stages, with and without condensers in between the stages. While both steam ejectors and diffusion pumps use jets of vapor to entrain ...

5. Jet injector - Wikipedia

   en.wikipedia.org/wiki/Jet_injector

   Since the late 1970s, jet injectors have been increasingly used by diabetics in the United States. These devices have all been spring-loaded. At their peak, jet injectors accounted for 7% of the injector market. Currently, the only model available in the United States is the Injex 23. In the United Kingdom, the Insujet has recently entered the ...

6. Vacuum engineering - Wikipedia

   en.wikipedia.org/wiki/Vacuum_engineering

   Vacuum systems usually consist of gauges, vapor jet and pumps, vapor traps and valves along with other extensional piping. A vessel that is operating under vacuum system may be any of these types such as processing tank, steam simulator, particle accelerator, or any other type of space that has an enclosed chamber to maintain the system in less than atmospheric gas pressure.

7. Pratt & Whitney J58 - Wikipedia

   en.wikipedia.org/wiki/Pratt_&_Whitney_J58

   The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
