  • Patent number: 10212896
    Abstract: An emitter (120) has, in a water intake part thereof, a water intake amount regulating part for preventing low-pressure liquid from flowing in. The water intake amount regulating part has a valve body (214) and a securing part (215). When the pressure of the liquid meant to flow into the emitter (120) is less than a set value, the valve body (214) does not move with the securing part (215), preventing the liquid from flowing into the emitter (120). When the pressure of the liquid is equal to or greater than the set value, the valve body (214) bends downstream to open the flow channel for the liquid.

  • Patent number: 10195471
    Abstract: A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.

  • Patent number: 10174730
    Abstract: A fuel injector for use in delivering fuel to an internal combustion engine includes a nozzle having a valve needle which is moveable with respect to a valve needle seating through a range of movement between a fully-closed position and a fully-open position to control fuel delivery through at least one nozzle outlet, whereby movement of the nozzle needle is controlled by fuel pressure within a control chamber. A nozzle control valve controls fuel flow into and out of the control chamber to pressurize and depressurize the control chamber, respectively. The fuel injector also includes a variable flow passage in communication with the control chamber through which fuel flows out of the control chamber at a variable rate throughout the range of movement of the valve needle so that movement of the valve needle is damped to a greater extent as it approaches the fully-open position.

  • Patent number: 10175032
    Abstract: A personal protection apparatus includes a wearable covering, a reservoir supported on the wearable covering and containing a sprayable fluid and includes a valve operable to control the flow of fluid from the reservoir. The apparatus further includes a circuit having a force-sensing resistor for actuating the valve. The force-sensing resistor is disposed on a thumb covering and is activated under pressure when the wearer's thumb is positioned between the index finger and middle finger. Pressure on the force-sensing resistor decreased its resistance in the circuit. With the resistance lowered, current is allowed to flow and a power supply powers a servomotor coupled to a cam that opens a valve to allow fluid to be sprayed.

  • Patent number: 10159861
    Abstract: A method for delivering a liquid contained in a reservoir, the reservoir having a port for delivering the liquid which is closed off by a blow-out disk that is removable at a threshold pressure applied to the liquid, includes: the combustion of a pyrotechnic charge to generate combustion gases, the pressurization of the liquid by the combustion gases, and the removal of the removable blow-out disk from the delivery port and the delivery of the pressurized liquid. The flow rate of generated combustion gases during the delivery of the liquid ensures virtually constant pressurization of the liquid and thus the delivery of the liquid at a virtually constant flow rate. The pressure of the liquid during the delivery of the liquid varying only by a maximum of +/?30% with respect to its initial value at the time at which the blow-out disk is removed.

  • Patent number: 10149992
    Abstract: A fire suppression system in which the water supply line (108) is fitted with repeating arrays of sprinkler heads (102, 106). Each array is substantially identical and is composed of two side-discharge sprinklers (106) and one vertical-discharge sprinkler (102). The side-discharge sprinklers (106) in each array are aimed so that their coverage areas point in opposite directions. The trigger (109) for the vertical-discharge sprinkler (102) has a lower activation temperature (Tv) than the activation temperatures (Th) of the side-discharge sprinklers (106) so that the vertical-discharge sprinkler (102) will activate earlier than either of the side-discharge sprinklers (106). The vertical-discharge sprinkler (102) may include a heat collector (104) to facilitate early activation of its trigger (109). The fire suppression system and method harness the working power of working of multiple orientations of fire sprinklers to produce, in effect, a super fire sprinkler system and method.

  • Patent number: 10112204
    Abstract: A tank holding a quantity of liquid releasably connects to an electric pump module through a connector to provide a portable sprayer. The tank connects to a feed line that supplies spray nozzle with the liquid. The connector combines a quick disconnect connector with a pressure relief valve. The electric pump module includes an electric pump, a switch assembly, and a check valve. The electric pump module directs gas through the check valve into the connector to increase the gas pressure in the tank and force the liquid in the tank to flow through the feed line and out the spray nozzle. The switch assembly turns off the electric pump when the gas pressure in the tank exceeds a predetermined limit while maintaining the flow of liquid through the spray nozzle.

  • Patent number: 10094350
    Abstract: The present disclosure relates to an injection valve. The valve may comprise a fluid inlet tube with a recess, a valve body, a valve needle, a spring element, and an elastic body. The valve body may have a central longitudinal axis and a cavity with a fluid outlet portion. The valve needle may be arranged in the recess of the fluid inlet tube and movable in the cavity. The spring element and elastic body may be arranged in the recess and interact with a portion of the valve body on one side and with a spring rest fixed to the valve needle on another side. The elastic body and the spring element are compressed as the valve needle is moved along the longitudinal axis away from its closing position. The elastic body, in the presence of a fluid pressure in the recess, exerts a fluid-pressure-dependent longitudinal force on the valve needle.
