Abstract

In a jet pump, the suction pressure (Po) generated may be kept constant within predetermined limits and times by varying the pressure ratio f(p) providing a prescribed value for the pressure ratio f(p) is determined by computer-aided iterative changing of an existing value of the pressure ratio f(p) using an algorithm and a measured value for the pressure (Pe) of the delivery fluid.
