Abstract: An air-assisted sprayer comprises a platform, a fluid cup, an air reservoir, a spray cap, a pressure line, a fluid reservoir and a poppet valve. The fluid cup is connected to the platform to hold a volume of fluid. The air reservoir extends through the platform and is configured to receive pressurized air. The spray cap is connected to the platform to receive pressurized air from the air reservoir. The pressure line connects the air reservoir with the fluid cup to pressurize the volume of fluid. The fluid reservoir extends from the fluid cup to the platform to provide pressurized fluid to the spray cap. The poppet valve is in fluid communication with the pressure line between the volume of fluid and the air reservoir to prevent fluid from entering the air reservoir.

Abstract: An airless spray pump is provided with a single-acting piston pump which allows the use of a low-cost yoke drive. Motor and pump shaft are offset for most efficient force utilization.

Abstract: An apparatus for maintaining an effective concentration of alkaline detergent in an aqueous medium in a warewashing machine, which apparatus comprises a batch-fill warewashing machine having an aqueous rinse system, an alkaline detergent dispenser and a sump sized for a predetermined volume of an aqueous solution of the alkaline detergent in the aqueous medium; a source of the aqueous medium fluidly connected to the rinse system; means for controlling the flow of the aqueous medium through the rinse system; diverting means for obtaining a predetermined portion of the aqueous flow from the rinse system and for directing the diverted portion through a metering cap and volume control to the alkaline detergent dispenser, thereby to dissolve the alkaline detergent; and means for directing the dissolved alkaline detergent to the sump; wherein the detergent is dispensed only in a rinse cycle and an effective concentration of alkaline detergent is maintained in the warewashing machine sump.

Abstract: A water-driven jet or venturi extraction means is used to remove, capture and cool the hot, highly humid air created within commercial dishwashers during a wash rinse or sanitization cycle. A cold water spray is used to create a pressure reduction zone which serves to draw in hot, highly humid air from the dishwasher. Water vapor cools and condenses on contact with the cold water spray within the venturi. The invention also serves to help vent the dishwasher. Cool, fresh air is drawn into the dishwasher while the hot air is drawn into the venturi.
