VORTEX CHAMBER FOR FLUID CONTROL VALVES

摘要

A fluid flow control apparatus includes first and second bodies, an inlet, and an outlet. The first body includes a slot, and the second body includes a vortex chamber. The second body is moveable relative to the first body to align the slot and the vortex chamber. The vortex chamber includes a chamber inlet section, an orifice, and a tapered section that has a frustoconical shape and tapers from the chamber inlet section to the orifice. The chamber inlet section is in fluid communication with the slot when the vortex chamber is aligned with the slot. The inlet is in fluid communication with the slot, and the outlet is in fluid communication with the orifice.
