ABSTRACT:
An ultra low volume pressure independent spray head is disclosed whereby low flow characteristics of point source devices can be applied to larger wetted areas. Device uses elastomeric flow control where the emission channel is large enough to purge particulate matter from it's channels and the spray head has large enough orifices to allow the particulate to pass unimpeded through the discharge arena. This device is designed to utilize flow rates of less than 2 gallons per hour and can compensate for pressures between 10 and 60 pounds per square inch. Construction of this device is through the use of polymers, but other materials can be used as the design is such as to allow for a large variety of applications. This device can be used in the agricultural or horticultural application and is adapted for use in vineyards and can be used singularly or in multiple head arrangements. Design of inlet portion allows for use with flexible or rigid water supply means.
