Abstract

The ejector consists of a convergent/divergent nozzle with an upstream connection to a supply of air or water. The downstream connection is the outlet. A lateral branch is the vacuum connection to a vessel or machine. Air or water flow through the nozzle induces a vacuum in the lateral branch. The vacuum in the vessel, or speed of the machine is regulated by adjusting the pressure of the air or water entering the inlet branch.

  NAME OF DEPOSITORS: Mr. CASTRONOVO Angelo

  
Mister GALLO Vittorio

  
 <EMI ID = 1.1>

  
operating both in air and at 1 "water, this type AV venturi can replace any vacuum pump and will give efficient performance without any maintenance and minimal energy consumption.

DESCRIPTION

  
By injecting air or water through a convergent, divergent, the Venturi type A.V. creates a vacuum according to the needs requested.

  
The characteristics of the venturi will be such that

  
 <EMI ID = 2.1>

  
vacuum pushes or not able to operate receiving or driving machines.

  
 <EMI ID = 3.1>
