A low pressure limited overspray handheld aerosol spray gun for spraying a two-component adhesive, a method for spraying a two-component adhesive and a two-component adhesive obtainable by that method. In manufacturing of larger objects, such as matrasses and furniture, adhesives are often applied to fix parts of the large object together. Most adhesives are applied using either air-spray equipment or air-assisted spray equipment.

The present disclosure provides an aerosol unit for an aerosol dispenser. The aerosol unit includes an axially oriented body, having a distal inlet part and a proximal outlet part. The aerosol unit also includes a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part. The carrier member includes through-holes which place the inlet part in fluid communication with the outlet part, and the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal.

A coating comprises a resin solution including a solution of neoprene latex and liquid asphalt emulsion and an accelerator solution including an aqueous solution of zinc sulfate powder and water. A spray system for applying the coating includes a spray gun having first and second nozzles, a first pump fluidly connected between the first nozzle and a resin solution reservoir for delivering the resin solution to the first nozzle at a first fluid pressure, and a second pump fluidly connected between the second nozzle and an accelerator solution reservoir for delivering the accelerator solution to the second nozzle at a second fluid pressure different from the first pressure. The accelerator solution may be aerated by a source of compressed air prior to discharge from the second nozzle.

The disclosure presents templates that can be useful in construction. Embodiments of the templates include a face, and two or more indicators. The indicators are located at one or more predetermined intervals on the face, and each indicator defines a window. Each window is of a predetermined length, and each indicator is coded to indicate that each indicator is located at one of the one or more predetermined intervals.

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 fluid dispensing device has a spool valve in a dispenser housing with a spool in a spool housing and a spool wall around the spool housing with entrance and an exit openings defined therethrough; an entrance channel in the dispenser housing proximate to the spool wall entrance opening; a force applying element in the entrance channel that applies force against the spool wall with entrance and exit ends with the exit end proximate to the spool wall; a hose adapter fitting with an entrance end extending out from and an exit end extending into the entrance and contacting the force applying element with a flow passage extending through it; and fluid communication through the hose adapter fitting flow passage through the force applying element and into an entrance opening in the spool wall; where the force applying element defines a tortuous path through which fluid must travel.

An airbrush that sprays liquid in a mist form. A supply of a compressed air and a supply of the spray liquid can be controlled at the same time only using a spray button included in a spray head. Accordingly, a loss of the spray liquid can be minimized, the airbrush can be maintained clean, and usability of the airbrush can be enhanced.

A fluid delivery system utilizes Bernoulli pressure differentials and kinetic forces is provided. The system includes a pressurized channel in fluid communication with a flexible pressurized line for translating pressurized fluids to a mixing chamber. The mixing chamber is also in fluid communication with a source channel receiving fluids from a flexible source line. The mixing chamber is configured for entraining the source fluids with the pressurized fluids 26 using Bernoulli principles. Kinetic valves may be used in conjunction with, or in lieu of, the Bernoulli siphoning.

A pressure washer for dispensing either water or a water-chemical mixture includes an injector for injecting chemical into water flowing through a hose at a relatively high flow rate. A sprayer connected to the hose has a passage having one upstream, one middle, and first and second downstream portions. The first downstream portion is connected to a high pressure conduit and the second downstream portion is connected to a high flow conduit less resistance to fluid flow than the high pressure conduit. A valve between the upstream portion and the middle portion selectively allows fluid flow to the middle portion of the passage. Another valve between the middle portion and downstream portion selectively allows flow to the second downstream portion and high flow conduit. Otherwise the valve directs flow through only the first downstream portion and high pressure conduit, which limits flow rate so as not to activate the injector.
