This paper presents a lumped network approach for the modelling and design of micro-hydraulic systems. A hydraulic oscillator has been built consisting of hydraulic resistors, capacitors and transistors (pressure controlled valves). The scaling of micro-hydraulic networks consisting of linear resistors, capacitors and inertances has been studied. An important result is that to make smaller networks faster, driving pressures should increase with reducing size.
