Abstract
A precompression pump sprayer has a stationary discharge and a reciprocable pump cylinder which squeezes the air out of the pump chamber to facilitate priming as the cylinder is plunged relative to a piston shifted by the plunger to open the discharge during priming. Once primed the piston is shifted to open the discharge upon a build up of pressure during plunger reciprocation. A container vent is controlled by operation of the plunger.
