Abstract
A continuous, extended spray pump which has two opposing and coaxial chambers. The upper chamber is fitted with an upper and middle piston urged upwardly by a spring, the lower chamber is fitted with an opposing piston urged upwardly by a spring. When the upper and middle pistons are depressed, pressure is built up and the lower piston moves downward. Discharge occurs when the lower end of the lower piston is deflected by nibs on the inside of the upper chamber.
