Exemplary two chamber foam pumps, refill units and dispensers utilizing the same are disclosed herein. An exemplary refill unit includes an inverted container having a neck located at the bottom of the container and a foam pump secured neck. The foam pump includes a first air pump chamber, a liquid pump chamber and a second air pump chamber. In addition, the pump includes a piston. The piston has a hollow central portion. A first air inlet aperture is located through a wall of the piston between the first air pump chamber and the hollow central portion. A liquid inlet aperture is located below the first air inlet aperture and between the liquid pump chamber and the hollow central portion. A second air inlet aperture is located through the wall the piston located below the liquid inlet aperture and between the second air pump chamber and the hollow central portion.

A sprayer system includes a trigger sprayer having a trigger, a pump mechanism, and a nozzle. The sprayer system further includes a solvent reservoir for accommodating a solvent substance and a bottle for accommodating a concentrate substance. Further, the solvent reservoir is positioned above the trigger sprayer and is in fluid communication with the trigger sprayer and the bottle is positioned below the trigger sprayer and is in fluid communication with the trigger sprayer.

A system is proposed for cleaning and sterilization wherein a carrier fluid is provided through a spray head having a mixing chamber, the flow of carrier fluid converted to a spray by the spray head. In the mixing chamber, ozone and ozone reaction products are mixed with the flow of carrier fluid to obtain a higher mixture of ozone and ozone reaction products in the carrier fluid immediately before the carrier fluid and ozone and ozone reaction products are dispensed as a spray.

A spray device, such as one used with a pressure washer, includes a housing, a chemical container coupled to the housing, and a chemical conduit coupled to the container. The chemical conduit has an inlet and an outlet forming a chemical flow path therebetween. The spray device further includes a chemical flow controller allowing a user to adjust a chemical flow rate through the chemical conduit. Further, the spray device includes a water conduit forming a water flow path through the housing, the water conduit terminating at a spray orifice. The chemical flow path and the water flow path merge at a point proximate the orifice.

A shower head includes a main body, a motor, a cleaning device and a liquid dispenser. The main body has a channel, an inlet and a plurality of outlets. The channel fluidly connects the inlet and the plurality of outlets. The motor is disposed in the main body and has a driving shaft. The cleaning device is connected to the shaft of the motor. The cleaning device has a cleaning portion exposed on the main body. The liquid dispenser is disposed in the main body and has an outlet terminal in fluid connection with the cleaning portion.

A high volume low pressure (HVLP) coating application system employing a rotary vane pump and manifold assembly that provides an improved source of air for increased spray gun atomization of high solid coatings and faster applications of more even coated surfaces with continuous HVLP pressures of 10 PSI at the spray gun output and the ability to power multiple spray guns and breathing apparatus from a single manifold system.

A dispenser that includes a nozzle that is configured to dispense a fluid. The dispenser also includes a pump in fluid communication with the nozzle and a pulsation dampener in fluid communication with the nozzle. The pulsation dampener has a spring biased movable piston. The dispenser is configured to, when the pump is activated, emit a substantially constant stream of the fluid from the nozzle for at least one second.

A fluid dispenser (1) for dispensing a cosmetic composition (2) comprises a housing (3), a dispenser head (4), at least one first receptacle (16) being connectable to a first reservoir (5) comprising a first fluid (6), and at least one second receptacle (17) being connectable or connected to a second reservoir (7), the second reservoir (7) being configured to receive a second fluid (8). The fluid dispenser (1) further comprises a mixing area (18) being in fluid communication with the dispenser head (4), the first receptacle (16) and the second receptacle (17). The mixing area (18) is configured such, that the cosmetic composition (2) is generated when a dose of the first fluid (6) is mixed with the second fluid (8) within the mixing area (18).

A device for dispensing a mist of an ophthalmic fluid includes a discharge opening for said mist, a mixing chamber communicating with said discharge opening, an air chamber holding a volume of air, a first drive operable to expel air from said air chamber, a fluid chamber for holding a volume of the fluid to be dispensed and communicating with said mixing chamber, a second drive for delivering a predetermined dose of said fluid to said fluid chamber, said air chamber communicating with said fluid chamber and with said mixing chamber, said device establishing one flow of expelled air flowing into said fluid chamber, so as to force liquid from said fluid chamber into said mixing chamber, and another flow of said expelled air flowing past said fluid chamber into said mixing chamber.
