A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

A nozzle for spraying substances, more particularly dispersions, emulsions or suspensions, and to a method for the open-loop or closed-loop control of the volumetric flow rate of a substance to be sprayed and/or of a gas of a nozzle suitable for spraying substances, more particularly dispersions, emulsions or suspensions. The nozzle includes an inner tube discharge opening and a constriction in an inner tube channel carrying the substance to be sprayed at a distance from the inner tube discharge opening.

A massage nozzle includes a nozzle housing and a nozzle core detachably attached in the nozzle housing. The nozzle housing is split-type and includes a cover mounted in a hole of a wall of a hot tub, a nozzle seat and a fastener. The cover includes an end ring and a side wall extending from the end ring. The side wall is conformed with the hole. The nozzle seat includes an inlet and a spray end which has a surface conformed with the side wall. The nozzle seat passes through and detachably connects with the cover. The outer circumferential surface of the spray end contacts with an inner surface of the side wall. The fastener is detachably sleeved on the outer circumferential surface of the nozzle seat and cooperates with the cover to fix the nozzle seat to the hot tub. The installation is convenient and the cost is reduced.

A multi-functional shower head attachment device with suction and pressure capabilities enables users to induce a pressurized flow of liquid, or suction with handheld device selectively removably couplable to a conventional shower head. The device includes a housing containing a fluid transport network that is selectively manipulated along a valve translation path to selectively induce a negative pressure vacuum, and a pressurized discharge of fluid. The vacuum is generated as the pressurized fluid is diverted through a configuration of conduits, past a venturi channel and through a secondary exit port; thereby creating the vacuum through adjacent, fluidly coupled conduits. The pressurized fluid discharge is generated as the incoming pressurized fluid is diverted directly through a series of conduits to an exit port. The housing is coupled to a handheld suction and pressure housing assembly through which the user washes, removes acne/oils, etc., with both suction and pressurized fluid discharge.

A stationary fertilizer sprayer assembly for watering or fertilizing a selected area includes a container that is comprised of a fluid impermeable material to contain a fluid fertilizer. A base is coupled to the container and the base rests on a support surface adjacent to an area to be fertilized. A dispensing nozzle is removably coupled to the container such that the dispensing nozzle is in fluid communication with the container and the dispensing nozzle is fluidly attachable to a water source to receive water. The dispensing nozzle includes a mixture valve that is positionable in a mixing position of a non-mixing position. In this way the dispensing nozzle can spray either pure water or a mixture of the fluid fertilizer and water.

Nozzle assemblies (10) for spray guns are disclosed. The nozzle assemblies (10) generally include a fluid outlet (100) extending along a fluid axis (102), the fluid outlet (100) including a fluid aperture (104) and a fluid side wall (164) defining the fluid aperture (104), an atomizing aperture (108) adjacent the fluid side wall (164) and at least partially surrounding the fluid axis (102), an atomizing inlet (110) configured to receive a pressurized gas, and an adjustment member (150) located on the nozzle assembly (10) and movable to: (i) an atomizing position such that the atomizing inlet (110) is in communication with the atomizing aperture (108), and (ii) a non-atomizing position such that the atomizing inlet (110) is not in communication with the atomizing aperture (108). The foregoing nozzle assemblies (810) allow dispensing of fluid coating media in both spray and bead patterns with improved ease of cleaning, superior spray performance, and adaptability with existing spray gun platforms.

A system, including a spray cap configured to couple to a spray tool, wherein the spray cap includes a body and an air shaping passage through the body. The air shaping passage includes a flow control passage, an expansion chamber downstream from the flow control passage, and one or more air shaping outlets downstream from the expansion chamber.

A kit for a spray gun including a sleeve delimiting an inner volume provided to contain a pressurized fluid, the sleeve being configured to be connected to a main body of a spray gun, the sleeve having a radial periphery delimiting a fluid outlet of the sleeve and at least one orifice emerging on the radial periphery and fluidly connecting the inner volume and the radial periphery, a connector having an intake end connected to the fluid outlet and a connecting end suitable for being connected to a cup so as to fluidly connect the cup to the inner volume of the sleeve, and a ring surrounding the sleeve and covering the fluid outlet outside the intake end of the connector.

Systems and methods for two-component mixing in a jetting dispenser are provided herein. A jetting dispenser includes a fluid chamber having a first fluid inlet providing a first fluid and a second fluid inlet providing a second fluid, wherein the first fluid and the second fluid mix within the fluid chamber into a mixed fluid. A method for dispensing a mixed fluid from a dispenser having a fluid chamber in fluid communication with first and second fluid inlets is also provided. A first fluid is provided to the fluid chamber via the first fluid inlet and a second fluid is provided to the fluid chamber via the second fluid inlet. At least a portion of a valve element is moved relative to a valve seat to cause dynamic mixing of the first fluid and the second fluid within the fluid chamber to produce the mixed fluid that is dispensed.

A trigger sprayer is described which utilizes a ball valve to control the flow of a carrier fluid such as water. The ball valve is actuated by a trigger which is biases to the open position by a torsion spring. Provision is made for the trigger sprayer to draw a chemical solution from a supply container and meter it through one or more outlet devices for providing streams in the form of fan or mist sprays, or other shaped sprays.
