Abstract
Abstract A jet pump in combination with a fluidic device or system, the jet pump receiving a small volume of high pressure fluid and supplying a larger volume at lower pressure to the fluidic device or system, utilizing the fluid at a maximum pressure of 2 p.s.i., the pump entraining fluid from an auxiliary source to provide the increased volume. Fluid under high pressure is passed through a nozzle into an expansion chamber connected to an auxiliary fluid source. The high velocity fluid stream emanating from the nozzle draws fluid from the auxiliary source and passes through a collector to an output. A feedback may be bled off the output to operate restriction means varying the fluid available from the ambient source, or the high pressure source.
