摘要： [Object] To provide an ejector and a vacuum generating device that are capable of reducing an installation space for a switching valve, the ejector, and a pipe and reducing the time and effort for an assembly work.
[Solution] An ejector 20 includes an ejector body 21 having an internal passage 27 and a negative-pressure generating mechanism 22 including a nozzle unit 23 that ejects compressed air and a diffuser unit 24 that generates a negative pressure by using compressed air ejected by the nozzle unit 23. The ejector body has a first attachment surface 20a to which a valve body 41 of a switching valve 40 is fixedly attached and a second attachment surface 20b to which a base body 18 of the manifold base 10 is fixedly attached. The first attachment surface has a first inflow port 28a for supplying compressed air to the negative-pressure generating mechanism by being connected to a first output port A of the switching valve, and this port communicates with the nozzle unit through a supply passage 28. The second attachment surface has a negative-pressure supply port 29c for outputting a negative pressure to the outside by being connected to a negative-pressure inflow port of the manifold base, and this port communicates with the diffuser unit through a negative-pressure communication passage 29.

摘要： A hydrokinetic amplifier 10 having a primary liquid input formed into a primary liquid jet surrounded by a motivating vapor that transfers vapor momentum to the primary liquid jet and accelerates the primary liquid jet through a minimum cross-sectional area 20 upstream of a diffuser is provided with a secondary inlet that admits a secondary fluid to merge with the primary liquid jet in a diffuser 16 beyond the minimum cross-sectional area. Without varying the primary inflows of liquid and vapor, the secondary flow varies inversely with the fluid flow resistance of the output load; and this can be used to vary the volume, pressure, and temperature of the output. The product of the pressure and volume of the combined flows can exceed the product of the pressure and volume of the primary flow, and change in the load resistance can be used to turn the secondary flow on and off for adding a material to the primary flow.

摘要： The invention relates to an inflating device containing a pressurized gas chamber arranged in a housing. To achieve small dimensions and a cheap structure, never-the-less maintaining a large capacity for the device, the pressure chamber constitutes a standard type of gas bulb (2), a discharge duct (7) in communication with the chamber being formed to provide ejector action for inducting air via secondary air passages (11) leading from the duct (7) to the outside of the housing and suitably provided with non-return valves.
