    Abstract: The present invention pertains to improved manually operated atomization systems which combine atomizing nozzles with high pressure, pre-compression type pump mechanisms in order to provide a consistent, high quality, finely-atomized spray of a comparatively higher viscosity fluid. The pre-compression pump mechanism ensures that the product will only be delivered when sufficient pressure is available for atomization regardless of the speed or authority with which the pump mechanism is actuated. When the fluid is discharged from the nozzle in a swirling, conical film, the fluid is broken up into a finely-dispersed mist which may then be directed toward the surface to be coated. Pump mechanisms for use with the present invention incorporate specific design features which facilitate the flow of comparatively viscous fluids with reduced flow resistance and hence reduced pressure losses, as well as providing enhanced structural integrity to better withstand such operating pressures and forces while providing improved reliability. The combination of pre-compression and comparatively higher operating pressures ensures that the comparatively higher viscosity fluid will be delivered to the nozzle with a pressure (and hence a velocity) that is comparatively high and within a comparatively narrow range. This in turn ensures a finely-dispersed product spray with a comparatively narrow range of particle sizes, under a wide range of actuation circumstances.

    Abstract: A trigger-type device for operating a pump of the axial displacement piston type against a bias spring, sprays liquids out of a handheld container. The pump has a delivery head which is movable axially with the piston and provided with a delivery conduit set at an angle to the displacement axis of the piston and lying in the same plane where the angular movement of the trigger lever takes place. The device includes a rocker lever which converts the angular movement of the trigger lever into a corresponding axial displacement of the delivery head to thereby drive the pump piston against the bias spring and produce the spray.

    Abstract: A trigger actuated sprayer for dispensing liquid products featuring a movable hinge point for the trigger handle in the form of a flexure. The flexure allows a constant orientation for the spray nozzle to be maintained by accommodating changes in radial distance as the trigger handle is depressed, while decreasing the complexity and parts count of the overall structure. A sealing member is incorporated into the piston and the cylinder of the pump for the device to reduce leakage of the liquid product when the pump is not used or is inverted.

    Abstract: A pumping system is disclosed in which a storage compartment formed by a spring-loaded piston and cylinder assembly cooperates with a trigger actuated, spring loaded piston and cylinder assembly to store some product during a pressure stroke and discharge that product on a subsequent intake stroke to maintain a stream or spray issuing from the system. In a preferred embodiment, the trigger is part of a lever so constructed as to apply to the trigger actuated piston and cylinder assembly a force which is greater than the force applied to the trigger by the finger of a person. The lever projects outwardly beyond the outlet orifice of the pumping system and forms a ramp and opening for returning drips from the outlet orifice to the trigger actuated piston and cylinder assembly and ultimately to the container. The storage compartment preferably includes a strainer which strains product flowing through the storage compartment in order to inhibit clogging of the outlet orifice of the pumping system. A vent structure is also provided which includes a guide for guiding the trigger actuated piston and cylinder assembly to prevent distortion of a resilient seal of the vent structure.
