Abstract: A fine particle sprayer including a nozzle for dispersing a liquid disinfectant into a spray plume of droplets and a means for directing pressurized air below the spray plume to increase droplet transfer efficiency, and above and around the spray plume to prevent errant droplets from drifting toward an operator. A sprayer system includes a sprayer, a housing, and a blower that may be removably attached to the sprayer for generating an air stream below the droplets to improve droplet transfer efficiency.

Abstract: Exemplary embodiments of self-adjusting sanitizer/disinfectant sprayers are disclosed herein. An exemplary self-adjusting sanitizer/disinfectant sprayer includes a tank for holding sanitizer or disinfectant, one or more batteries, a motor, a motor controller, and a pump. The pump includes a pump inlet in fluid communication with an interior of the tank and a pump outlet. A processor, a dispensing wand and a flow sensor are also included. The flow sensor and motor controller are in circuit communication with the processor. The processor provides input to the motor controller for controlling the speed of the motor that drives the pump as a function of a signal indicative of the flow rate received from the flow sensor.

Abstract: The present invention provides a plumbing fixture fitting having a spray mode with improved spray performance. The fitting includes a spray face. The spray face includes nozzles. The nozzles are operable to deliver water from the spray face in the form of a spray. The spray includes streamlets. An average unbroken length of the streamlets is greater than approximately two inches at a flow rate of approximately thirty-seven thousandths gallons per minute.

Abstract: The present invention provides a plumbing fixture fitting having a spray mode with improved spray performance. The fitting includes a spray face. The spray face includes nozzles. The nozzles are operable to deliver water from the spray face in the form of a spray. The spray includes streamlets. A velocity of the spray from each of the streamlets is greater than approximately two-hundred fifty inches per second at a flowing pressure of approximately sixty pounds per square inch. In exemplary embodiments, each of the streamlets has a substantially uniform width along an entire length of the streamlet, an average unbroken length of the streamlets is greater than approximately two inches at a flow rate of approximately thirty-seven thousandths gallons per minute, and a splash created from the spray is less than approximately twenty percent at approximately one and a half gallons per minute.

Abstract: A one-handle valve cartridge has a low point of contact for installing the valve cartridge in a valve body. A retention nut bears down on the low point of contact to secure the valve cartridge in the valve body.

Abstract: One-handle and two-handle valve cartridges have an increased maximum flow rate and/or a decreased size (e.g., volume). Accordingly, the valve cartridges achieve an improved flow rate to volume relationship.

Abstract: The present invention provides a faucet including a cartridge assembly with a radially offset key.

Abstract: The present invention provides a faucet including structure to ensure components of the faucet are properly and securely assembled together. In one embodiment, the faucet includes a valve body, a mounting tube, and a hose retainer. The valve body is operable to receive at least a portion of a cartridge assembly and to connect to at least two hoses. The mounting tube is operable to mount the faucet to a surface, to receive at least a portion of the valve body, and to connect to at least two hoses. The hose retainer is operable to interface between the valve body and the mounting tube and to connect to at least two hoses. The valve body, the mounting tube, the hose retainer, and the hoses include structure to ensure that the valve body, the mounting tube, the hose retainer, and the hoses are properly and securely assembled together.

Abstract: A one-handle valve cartridge has a housing that functions as a stop for an actuating mechanism of the valve cartridge to define a range of flow rates and/or temperatures for which the water flowing through the valve cartridge is delivered.
