ABSTRACT:
A two stage pressure build-up discharge valve assembly is mounted within the end of the discharge nozzle surrounded by a nozzle cap of a trigger actuated pump sprayer, and includes a spring biased discharge valve element having a high pressure throttle valve fixed to a second stage low pressure valve piston to provide a predetermined pressure threshold which when exceeded by fluid pressure generated by the pumping force applied during trigger actuation unseats immediately permitting the fluid pressure to act upon the low pressure secondary valve piston rapidly snapping the valve element to a full open flow position.
