  • Patent number: 9033262
    Abstract: A liquid deflection device for the nozzle of an existing spray head wherein the device is rotatably mounted on the nozzle. The device has an attaching end which clips to an existing nozzle. The attaching end is opposite a handle end which a user grasps to rotate the device to block a portion of liquid being released from the exit port of a nozzle. A deflecting end extends beyond the top of the nozzle and has a shape and size sufficient enough to deflect liquid released from the exit port. A securing portion has an opening great enough in diameter to allow a fastener of sufficient size to secure the nozzle. An additional opening on the securing portion allows a user access to a set screw on the nozzle.

  • Publication number: 20150115066
    Abstract: A liquid diffuser device for irrigation systems includes a support structure defining a first longitudinal axis with an upper passageway for a liquid jet and a lower tubular body having a bottom wall, a spherical member associated therewith having an outer surface with a predetermined average radius of curvature, a liquid jet deflecting member having an upper plate and a lower stem designed to be introduced into the tubular body and defining a second longitudinal axis. The stem interacts with the outer surface of the spherical member, to allow rotation of the stem relative to the body and nutation of the second axis relative to the first axis. The bottom surface is concave to define with the spherical member a relatively broad and substantially uniform contact surface, to reduce the local specific pressure, thereby decreasing friction, wear and vibrations on the stem and the spherical member during operation.

  • Patent number: 8950694
    Abstract: A fuel injector body has a fuel chamber and a valve seat around a fuel outlet. A valve body is positioned at the valve seat and a valve stem extends through the fuel outlet and fuel chamber. Engagement (disengagement) of valve body and valve seat closes (opens) the injector. The fuel chamber can comprise primary and secondary chambers connected by a valve passage and a metering member that restricts fuel flow between the chambers, thereby providing a flow-dependent closing force that reduces the dependence of fuel flow through the injector on fuel inlet pressure and that makes that flow dependent on an injector actuating force. The injector body or the valve body can comprise a spray-shaping surface arranged at least partly around the valve seat, which spray-shaping surface is arranged to direct a spray of fuel flowing through the fuel outlet.

    Abstract: A faucet aerator is provided with a plurality of pins oriented in a flow direction, spaced apart from one another, and extending essentially over the distance between a flow-dispersing device and an adjacent grid and/or lattice structure. The pins each have an evaporation surface, which is situated outside the region that is struck directly by the individual streams but can be wetted by the water flowing through the aerator housing and for this purpose, the pins are situated laterally outside the projection of the through-flow holes oriented in the flow direction. These comparatively long pins around which the flowing water circulates are covered by an enveloping water film even after the water valve is closed, which results in an increased humidity and therefore a reduced evaporation in the housing interior of the aerator housing. This prevents a complete drying-out of the interior of the aerator housing.

  • Publication number: 20120255292
    Abstract: A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.

  • Publication number: 20120205467
    Abstract: One embodiment provides an asymmetrical nozzle housing within a nozzle base of a sprinkler which, when rotated, changes its angular orientation relative to the nozzle base. Since the nozzle is disposed within the nozzle housing, it similarly changes angular orientation relative to the nozzle base, thereby modifying the trajectory of ejected water during irrigation. In this respect, a user can change the trajectory of a watering stream by simply rotating the nozzle housing.

  • Patent number: 8231069
    Abstract: In a fuel injection nozzle for an internal combustion engine, a first cavity is disposed downstream of a valve seat in a direction in which fuel flows. A second cavity is disposed downstream of the first cavity in the direction in which the fuel flows. A fuel passage connects the first cavity to the second cavity. Fuel injection holes (24) lead to the second cavity. With this configuration, when the fuel flows through the first fuel passage, cavitation is induced. Cavitation bubbles flow into the second cavity along with the fuel. When the fuel is retained in the second cavity, the cavitation bubbles are uniformly mixed into the fuel. The fuel, which has been sufficiently mixed with the cavitation bubbles, is injected from the fuel injection holes.

  • Patent number: 8214935
    Abstract: Pop-up fountain embodiments are provided which successfully combine aesthetics, utility and ease of installation and are thus especially suited for installation into spas, hot tubs, pools and the like. Different embodiments include a fountain body and a fountain valve which is slidingly received in the body. The valve terminates in a cap which substantially fills an aperture of the body when the valve is in a quiescent position. Applied water pressure forces the valve into an energized position where the form of the valve directs water laterally in an aesthetically-pleasing pattern. The valve preferably includes a deflector which is arranged below the cap and configured to control and enhance the lateral deflection.
