Abstract
A precompression pump sprayer is primed by the provision of a priming ramp for deflecting the lower end of a poppet valve member at the end of the plunger downstroke for cocking the valve member so as to disrupt its sealing action with the discharge valve seat to thereby permit air to be released from the pump chamber through the discharge orifice and to the atmosphere.
