  • Patent number: 10240793
    Abstract: A manifold fitting receiving radial and axial manifolds and providing two radial outlets is disclosed. The manifold fitting, when used in conjunction with a fuel injector and a combustor for a gas turbine engine, reduces the radial footprint of the fuel injector and thereby allows for a more compact engine. Additionally, the manifold fitting eliminates parts, reducing weight in the process, as compared to prior art fittings. Such reductions in size, parts count, and weight are particularly beneficial for aircraft applications.

    Abstract: A device for generating a scented mist of an atomized liquid fragrance oil includes an atomizer complex, a reservoir assembly, a drainage tube, and a vacuum tube. The atomizer complex can atomize the liquid fragrance oil into a scented mist and deliver the scented mist to air outside of the atomizer complex, where the liquid fragrance oil the fragrance oil that is not atomized into the scented mist delivered to the air outside of the atomizer complex includes collected oil that is collected and drained to a reservoir assembly. A drainage tube extends from a bottom area of the atomizer complex into the liquid fragrance oil. The device can filter the liquid fragrance oil in the reservoir assembly and the collected oil from the atomizer complex that drained down the drainage tube. The vacuum tube can suction the filtered liquid fragrance oil and the collected oil into the atomizer complex for atomization.

  • Patent number: 8910882
    Abstract: A fuel injector for an engine is disclosed. The fuel injector may have a fuel nozzle with at least one injection orifice, and a needle element movable within the fuel nozzle between a first position at which the needle element inhibits fuel flow and a second position at which fuel flow is substantially uninhibited. The fuel injector may also have a control chamber located at a base end of the needle element, a body, and a control valve disposed within the body and movable to selectively drain the control chamber, thereby causing the needle element to move between the first and second positions. The fuel injector may further have an armature disposed within an armature cavity of the body and selectively energized to move the control valve, and a pressure reducer disposed within the body and configured to reduce a pressure of the armature cavity.

  • Patent number: 8888016
    Abstract: A pressure washer device is provided that employs an unloader bypass valve that directs a selective amount of fluid via a small diameter bypass line back to a water storage tank. The small amount of fluid allows for the pump to remain working and introduces cooler water into a bypass circuit, thereby allowing the thermal relief valve to be omitted. The diameter of the bypass line is of such a diameter to prevent siphonage of the detergent associated with the pressure washer system into the water storage tank as well.

  • Patent number: 8727233
    Abstract: A method and apparatus is provided for starting and stopping a high pressure spray washer having a combustion engine driving a pump to provide high pressure fluid to a spray gun activated by a trigger. Pulling the trigger causes water to flow through the nozzle and pump and a sensor by the pump sends a flow start signal to a control module that activates an electric starter when an engine switch is turned on, thus starting the engine when it wasn't running. When the trigger is released flow to the pump stops and the sensor sends a flow stop signal to the control module. If a predetermined time passes before the sensor detects fluid flow to the pump as occurs when the trigger is pulled, then the engine is shut off. The time can be varied to adjust the time between releasing the trigger and shutting off the engine.
