    摘要： A manually actuated pump sprayer of the type having a discharge nozzle cap in engagement with a probe, spin mechanics formed between the cap and the probe. A generally cylindrical fluid flow dampening chamber, formed at the end of the probe in communication with the spin chamber or being integrated with the spin chamber, has a non-smooth sidewall defined by at least one projection extending toward the axis of the probe for reducing spin energy of the fluid spinning in the dampening chamber and/or in the spin chamber about the axis to effect a solid spray cone of fluid exiting the orifice.

    摘要： A sprayer has a nozzle assembly which includes first and second fluid flow paths, the latter partially negating the spin velocity produced from the first path to effect a spray having a narrower spray cone. The second fluid flow path is established by a through opening located in a spinner probe, which opening is blocked and unblocked upon relative rotation of a surrounding nozzle cap.

    摘要： A sprayer has a spray pattern which can be varied by the provision of a second fluid flow path which partially negates the spin velocity to produce a spray having a narrow spray cone producing spray. An opening in the spinner probe establishes the second fluid flow path from the discharge passage, and can be selectively opened and closed upon plunger rotation relative to a hollow piston stem.

    摘要： A precompression pump sprayer has a variable volume suck-back chamber in communication with the discharge orifice for inwardly suctioning any residual liquid away from the orifice and the spin mechanics to avoid clogging as a result of dried accumulated product. In one embodiment a cover on the plunger head is spring loaded and therewith defines the suck-back chamber. In another embodiment the plunger head is spring loaded on the piston stem, such that in both embodiments a top end wall of the suck-back chamber is shiftable relative to the piston stem independently of piston reciprocation. The biasing spring has a spring force permitting a shifting of the end wall to reduce the volume of the suck-back chamber at a peak pressure reached in the pump chamber beyond the threshold pressure required to open the discharge valve, at which time the spring is compressed. The restoring force of the spring causes the top end wall to shift to expand the volume of the suck-back chamber.
