Abstract: Hydraulic amplifiers are needed in the large flows [ 0.05 to 5 m3/s (800 to 80,000 GPM)] and moderate pressure [ 30 to 200 N/cm2 (45 to 300 psi)] class.The axisyrnmetric focusedjet amplifier appears particularly suited for this application.A model has been built and tested a t supply pressures up to 27 N/cm2 (40 psi) and supply flows up to 0.01 m3/s (160 GPM).Pressure recoveries and power efficiencies of the order of 50 percent have been achieved.Pneumatic control without mechanical interface has been developed, exploiting a standing cavitation bubble within the control cavity.
