Abstract

The fluid system operates a varying pressure impulse drive for a fluid pump. It has a drive circuit with a fluid load amplifier. A switching circuit with a fluid oscillator is connected to a common fluid pressure pipe to produce a main flow path through the entire system. The load amplifier and oscillator each have a main fluid inlet and various outlets and control fluid flow outlets which are cut off from one another. A back coupling circuit with a fluid flow retard device controls the main flow through the oscillator.
