Document Type and Number:
Japanese Patent JPH0437283
Kind Code:
B2
Abstract:
The invention relates to fluidic transducers of electrical signals from an electronic computer for accurately metering flow of a liquid to a utilization device. A liquid filled hollow channel means is accelerated along the flow axis thereof to produce a fluid control signal for a bistable fluidic switch element having a pressurized, cross-over type interaction region leading to a common outlet and to a pair of output passageways. In a preferred embodiment, electrical signals from an electronic computer are supplied to a coil centered by a spring in a magnetic field, first in one direction of current flow and then in the opposite direction, to introduce bidirectional movement of the coil and the hollow channel means coupled thereto. The signals are preferably frequency modulated (but may be pulse width modulated).
