  • Patent number: 7156320
    Abstract: A clog-resistant injector spray nozzle allows relatively unobtrusive insertion through a small access aperture into existing ductwork in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle comprises an easily cleaned and easily replaced straight liquid tube whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube until they both exit the injector, thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.

  • Patent number: 7140562
    Abstract: A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle situated in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle and faces the combustion chamber is kept in sealing contact with a valve-seat surface in the non-actuated state of the actuator. A first jet-opening angle ?1 is assigned to a first lift state of the valve needle and a second jet-opening angle ?2 to a second lift state of the valve needle.

  • Patent number: 7137575
    Abstract: A nozzle for use with a fire hose is capable of varying a discharge pattern while maintaining the total water discharge amount at a fixed level. A first tube 4 is connected to a fire hose, a second tube 5 is screwed onto the first tube, and a throttle valve 40 is disposed on the inside of the second tube. A throttled portion 10 between the second tube and the throttle valve maintains the total water discharge amount at a fixed level. The position of the second tube 5 is varied by rotating a grip 42, and thus the total water discharge amount setting is varied. A third tube 13 is screwed onto the second tube, and a fourth tube 14 is screwed onto the third tube. The position of the third tube 13 is varied by rotating a grip 60, and thus the discharge pattern is varied. The position of the fourth tube 14 is varied by rotating a grip 66, and thus the flow rate of a self-protection water spray is regulated.

  • Patent number: 7131598
    Abstract: A snow-gun for producing man-made snow from a combination of compressed air and water features a new nozzle configuration for discharging a mixture of water-particles and air into the surrounding atmosphere. Such nozzle is provided with an elliptically-shaped discharge port having a transverse cross-section that gradually expands in size in the direction in which the air and water particles are discharged from said nozzle. Preferably, the area of the elliptical port changes non-linearly through the front wall of the nozzle, whereby water particles exiting the gun through the nozzle port are less likely to collide with the side walls of the port or with each other before reaching the relatively cold ambient atmosphere.

  • Patent number: 7121354
    Abstract: A fire extinguishing device and associated methods. The device is adapted to be positioned in proximity to a fire and operable in response to heat output by the fire. The device includes a first reservoir, containing a fluid, adapted to receive the heat from the fire and thereby exert a pressure and a second reservoir, communicating with the first reservoir, containing a fire fighting material. The device further includes a pressure-sensitive membrane, forming a pressure-sensitive barrier between the first reservoir and the second reservoir, adapted to rupture upon a predetermined pressure being attained in the first reservoir and thereby releasing a steam into the second reservoir. The steam expels the fire fighting material onto the fire. Additionally disclosed are methods for using the device to control and extinguish fires.

  • Patent number: 7118051
    Abstract: A rotor nozzle includes a nozzle housing having an inlet opening at one end and an outlet opening at another end and has a rotor which is arranged in a turbulence chamber and which is provided at its front end facing the outlet opening. A nozzle is supported in a cup bearing and has an inflow opening. A bypass device changes a radial or a tangential component of the liquid flowing into the turbulence chamber, which sets the rotor into rotation. A control surface is provided in the turbulence chamber. A restoring device is provided which is active between the front end of the rotor and the rear rotor end, wherein as the rotor rotary speed increases, the inclination of the rotor increases against the action of a restoration force of the restoring device and the restoring device reduces the rotor inclination as the rotor rotary speed decreases.
