ABSTRACT:
A flow control device that is uniquely capable of providing uniform flow under changing environmental conditions of temperature and pressure. The device achieves flow rate stabilization by taking advantage of the properties of the moving fluid in a channel with eddy currents that are generated as fluid moves past obstacles located in the fluid flow path. The shape and magnitude of such eddies depend on the viscosity of the fluid. Additionally, the device can also simultaneously stabilize the fluid flow rate under varying pressure by using a strategically positioned, yieldably deformable elastomeric membrane. Therefore, the invention uniquely combines two devices into one novel fluidic device that can stabilize a flow rate under simultaneously changing temperatures and pressures.
