A backpack blower is provided with a water spray capability to suppress the generation of dust when used as a blower, and to also allow for use as a basic power washer. A leaf blower power unit having an engine driving a fan is interconnected with a wand having an outlet orifice. A spray nozzle is positioned within the wand adjacent the outlet orifice. A source of liquid to be sprayed is interconnected through a control valve to the spray valve such that a spray of water can be introduced into the vortex of the air being emitted from the wand. Both the speed of the airflow and volume of the water being introduced into the vortex may be regulated by the user in accordance with the use to which the unit is put.

A painting system used in a painting method in which a plurality of colors of paint supplied from a paint supply device are mixed and toned with a mixing device and applied to a workpiece, the painting system comprising a storage unit that can store the paint that is mixed and toned with the mixing device, and a cleaning unit that can clean the mixing device. When applying the paint in the storage unit to the workpiece, the cleaning unit cleans the mixing device.

A flow control assembly includes a manifold coupled to a positive displacement pump. A fluid input unit is coupled to the fluid inlet and includes a diluent input to receive a diluent and a concentrate input to receive a selectively adjustable flow of a liquid concentrate. A mixing chamber combines the diluent and the liquid concentrate to form a mixed solution to be delivered to the pump. A bypass unit has a bypass conduit to receive a high pressure mixed fluid from the pump. A bypass valve is positionable within the manifold between a closed position and an open position. The bypass valve is closed when the high pressure mixed fluid is below a threshold pressure and open when the high pressure mixed fluid is above the threshold pressure. A portion of the high pressure mixed fluid is reintroduced to the mixing chamber via the bypass inlet.

A fire suppression nozzle assembly includes a spray-type nozzle for spraying a fire suppression fluid. The spray-type nozzle includes a body portion defining a passage extending longitudinally through the body portion for conveying the fire suppression fluid. The spray-type nozzle also includes a deflector portion coupled to the body portion and configured to spray the fire suppression fluid onto a fire suppression target area using a radial spray pattern.

An apparatus for injecting liquid fertilizer into a water flow line in a sprinkler system, includes an injector mechanism body having a water inlet and a water outlet adapted to be connected in the water flow line of the sprinkler system so that water flows through at least a portion of the injector mechanism body, a plunger chamber, a plunger movably positioned in the plunger chamber, a paddle wheel positioned to be rotated by water flowing through the injector mechanism body, a plunger gear coupled to the paddle wheel and the plunger so as to rotate when the paddle wheel rotates so as to move the plunger back and forth within the plunger chamber and a valve assembly secured at a fixed location in the plunger chamber.

The present invention addresses the problem of providing an atomizer that is easy to handle and that is particularly suitable for atomizing a cosmetic material. The present invention comprises: an atomizer body 2 that has a coating composition atomizing head 2a at a leading end thereof; a pressure tank 3 that is filled with a compressed gas; and a gas supply pipe 4 that supplies the pressurized gas to the atomizing body from the pressure tank. A composition supply tank 5 that supplies the coating composition and an operation part C that causes the coating composition to be sprayed from the atomizing head are provided between the leading end and a trailing end of the atomizer body. A substantially ovoid-shaped gripping part G that is gripped by the palm of a hand of a user is formed at the trailing end of the atomizer body.
