An apparatus is disclosed for dispensing a precise volume of liquid. An emitter dispenses a stream of liquid to an appropriate collector and includes an outlet restriction for generating a positive pressure in the emitter behind the outlet restriction. Liquid is fed to the emitter under pressure. A time delay loop is provided in communication with the emitter behind the outlet restriction for receiving liquid therefrom under the influence of the positive pressure. The exit end of the time delay loop directs liquid received thereby against the stream of liquid dispensed by the emitter and diverts the stream of liquid away from the collector when the time delay loop becomes filled with liquid under pressure from the emitter. A fluid amplifier is provided for generating a laminar liquid power stream to the emitter and for controlling the on-off cycle of the apparatus.

An apparatus for dispensing a precise volume of liquid, comprising: emitter means for dispensing a stream of liquid to an appropriate collector, the emitter means including outlet restriction means for generating a positive pressure in the emitter means behind the outlet restriction means; supply means for feeding liquid under pressure to said emitter means; and time delay conduit means in communication with said emitter means behind said outlet restriction means for receiving liquid therefrom under the influence of said positive pressure, the time delay conduit means being positioned for directing liquid received thereby against the stream of liquid dispensed by the emitter means and diverting the stream of liquid away from said collector when the time delay conduit means becomes filled with liquid under pressure from the emitter means.
