Fluidic mud pulser

摘要

A liquid telemetry system is disclosed useful for transmitting data through a fluid body by means of pulses in the fluid. To generate the pulses in the fluid the system utilizes a bi-stable fluid amplifier in conjunction with a vortex valve. Control input signals direct the flow of fluid from the bi-stable amplifier into the vortex valve in such manner as to selectively impede the flow of fluid through the vortex valve. The resulting changes in fluid flow rates generate pulses within the fluid body.
