Abstract:

Disclosed is a vacuum steam-jet pump, comprised of a casing (1) containing the steam lines for a third jet stage (8) and a second jet stage (10) disposed in succession. An additional steam line (16) with additional apertures (17) is disposed symmetrically with respect to the axis of the third stage jet, the total area of said apertures being larger than the area of the apertures (14) of the membrane (13). Said membrane is set in the small base of a hollow truncated cone (12) disposed at the exit point of the second stage steam line. The additional steam line is connected with an umbrella-shaped structure (18) and forms an edge gap (19) with the nozzle (20) of the first stage. The area of the apertures (14) on the membrane (13) is greater than the area of the edge gap. The body further houses a rod (7) with an adjustable position, on which the three steam line stages are disposed, and a shaped head (21), set above a space over the umbrella.
