    Abstract: A spraying apparatus for applying a friction modifying fluid to a railroad rail, comprising: a nozzle body disposed in a housing; a fluid inlet conduit in fluid communication with an opening in housing; a fluid inlet disposed in the housing in fluid communication with a first fluid conduit defined by or disposed in the nozzle body; wherein the first fluid conduit runs from fluid inlet to a hollow nozzle tip body disposed on and protruding through a bottom of housing and wherein fluid inlet is also disposed below, and in fluid communication with, the fluid inlet conduit; a control fluid supply line and an atomizing fluid supply line each partially disposed in the housing and each having respective portions external of the housing for connecting with the same fluid supply or respective fluid supplies; wherein the control fluid supply line injects a pressurized control fluid against a piston assembly disposed in a piston cavity; wherein the piston assembly carries stopper needle which is biased towards hollow nozzle tip body by a spring so that the needle closes a nozzle tip opening of hollow nozzle tip body; wherein the atomizing fluid supply line provides a pressurized atomizing fluid into hollow nozzle tip body to atomize the first fluid supplied by the first fluid conduit into the hollow nozzle tip body via a fluid cap disposed on the hollow nozzle tip body; wherein in operation the control fluid supply line and the atomizing fluid supply line are operated simultaneously while the first fluid is supplied by the first fluid conduit into the hollow nozzle tip body via a fluid cap such that the pressurized control fluid injected by control fluid supply line against a piston assembly displaces needle out of the nozzle tip opening and allows the first fluid to exit out of the nozzle tip opening where the first fluid is atomized by the pressurized atomizing fluid supplied by the atomizing fluid supply line.

    Abstract: An embodiment of the present invention is an air brush including a housing, a head assembly, and a trigger assembly. The housing has a main body with an air valve, reservoir and a handle. The head assembly mounts to the main body with a nozzle, nozzle cap, and a needle cap. The trigger assembly fits within the housing and includes a needle engaging the head assembly, a needle chucking guide, a needle chucking nut, a lever assembly, a spring guide and a spring device. The lever assembly actuates the needle to release compressed air and contents of the reservoir. The spring device controls release of the contents relative to the air flow through the air valve and nozzle. The spring device includes a first spring, a second spring, and a ring member. The ring member is positioned between the springs, and the springs have different strengths.

    Abstract: A dispensing head for emitting an atomized spray of liquid droplets includes an actuator and a nozzle insert. The actuator includes a gas duct and a liquid duct and may be attached to a container housing a propellant gas and a liquid product. The nozzle insert includes at least one modular structure that can be installed in an actuator socket on the actuator. The nozzle insert includes a pressure cap defining a pressure chamber having an exit orifice. A liquid conduit is disposed in the pressure chamber and defines a liquid supply channel having a liquid supply channel exit opening. The nozzle insert is configured to form a reflux cell in the liquid supply channel upstream of the liquid supply channel exit opening to achieve flow blurring interaction between the liquid product and the gas propellant.
