This paper presents a fundamental study on a bistable fluid amplifier load oscillator. To make preliminary clarification of the effect of the amplifier on the oscillating system, the flow characteristics of the amplifier is discussed in terms of solving steady two-dimensional Navier-Stokes equations by computer. And experiments are also carried out. The results obtained are summarized as follows : (1) Wall-attachment phenomenon of the jet which is essential to the operation of a bistable fluid amplifier may appear in laminar flow region. (2) To construct a mathematical model of the fluidic load oscillator, it would be reasonable to represent the amplifier's characteristics by the plots of the pressure difference versus the flow difference between both amplifier branches. (3) Using thus represented characteristics, it is easily explained that a bistable fluid amplifier can cause self-sustained oscillations in the system.
