    Abstract: A dispenser (1) comprises for its plunger chamber (13) an outlet valve (20) which after opening on the actuating stroke continues to remain open for a time during the subsequent return stroke due to a delay means (30) so as to ensure a more or less complete venting or filling of the plunger chamber (13). At the end of the delay period the closure maintained in the open position position by friction surface areas (37, 38) is released and automatically jumps back into its closed position. After venting, the effectiveness of the delay means (30) diminishes so that in normal operation substantially only a pressure dependent opening and closing of the outlet valve (20) is provided for.

    Abstract: A manual spray dispenser for pressurizing a liquid to a predetermined pressure is provided. The spray dispenser includes a pressure adjustment assembly to adjust the predetermined pressure between a preselected range of pressures. The pressure adjustment assembly includes an adjustable biasing member to supply a force to a pressure chamber check valve in a direction opposite the flow of liquid from the reservoir to the atmosphere so that the pressure in the delivery passageway can be varied. Optionally, a two-hole rotating nozzle is provided in combination with a pressure adjustment assembly. In another aspect of the invention, an exit orifice purge system is provided to reduce dripping from the nozzle in the manual sprayer after dispensing.

    Abstract: A precompression pump sprayer comprises a hollow piston and a plunger rod having a discharge passage and a lower enlarged end forming a discharge valve seat, the rod extending through the piston for reciprocation between an inactive position and an end-of-stroke position, the piston engaging the valve seat in a discharge closed position, a primary spring biasing the plunger rod toward its inactive position, and a secondary spring biasing the piston into engagement with the discharge valve seat, the valve seat being of conical or curved shape, and the piston having a shoulder defining a discharge valve for solely contacting the valve seat along a thin circular line without sliding for quickly and cleanly valving the discharge passage open and closed during plunger actuation.
