Abstract: An anti-clog pump sprayer has a cover mounted for independent reciprocation on a plunger head, the cover having a cupped spring biased portion covering the discharge orifice on the head to avoid clogging on product drying, and being lifted off the orifice during the relative shift for uncovering the orifice in readiness for spraying. The sprayer may also have a product retraction device on the plunger head in communication with the discharge orifice, a projection on the underside of the cover top wall for actuating the device at the commencement of the plunger return stroke for creating a slight sub-atmospheric pressure for suctioning any residual product inwardly of the orifice to thereby avoid clogging.

Abstract: A pumping system includes a chamber (10) having an intake orifice (11) for introducing liquid into said chamber (10). A discharge orifice (12) discharges the liquid from the chamber (10). Another orifice (13) receives pressurized gas. A valve is located at each of the orifices (11, 12, 13). The valves (15, 16, 17) are controlled in synchronization according to two phases. During the first phase the valve (15) opens at the intake orifice (11) while the other two valves (16 and 17) are closed, in order to fill the chamber (10). During a second phase the valve (15) associated with the intake orifice (11) is closed while the other two valves (16 and 17) are open, this enabling pressurized gas to be introduced into the chamber (10), thereby expelling the liquid in the chamber (10) through the discharge orifice (12).

Abstract: A plastic bottle for spraying liquid has a liquid chamber defined by a sidewall. The sidewall terminates in a neck having a neck opening. A tube integrally formed alongside the sidewall leads from the bottom of the liquid chamber up to a nozzle. A top end of the tube is inclined away from the neck, and a squeeze bulb is in liquid communication with the tube. By squeezing the squeeze bulb, liquid is drawn from the liquid chamber, through the tube, and out through a nozzle attached to the top end of the tube.

Abstract: With this device the fluid is located in a container which can be set under pressure, into which two cannulas of differing lengths may be inserted. A short cannula, via a gas conduit and a release valve, is connectable to a pressurised gas source in order to impinge the container above the fluid level with pressurised gas, whilst the other longer cannula is connectable to a fluid conduit leading to the instrument and protrudes into the fluid located in the container. The fluid flow to the instrument is interruptable with a blocking element and the pressurised gas supply to the container is interruptable with the release valve. Such a device may be simply constructed and used when, according to the invention, the cannulas, the blocking element and a control valve are grouped together into a constructional unit on which there is located one connection for the gas conduit and a further connection for the fluid conduit.

Abstract: The present invention provides a spray head assembly with a moving spray nozzle that delivers fluid in a substantially uniform spray distribution. The movement of the spray nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the spray housing and nozzle to wobble. The spray pattern produced by the wobbling spray housing changes more or less rapidly so that fluid droplets or streams are directed along arcuate paths rather than at a single point. This type of spray distribution pattern is gentler than many stationary patterns and the unique design of the wobble inducing member does not include complex mechanical parts or significant flow restrictions.
