  • Patent number: 6116475
    Abstract: A dispensing head for a container holding a product of liquid-to-pasty consistency includes a body in which a product outlet orifice and a closure member for selectively closing off the orifice are provided. The closure member includes of a member made of an elastically deformable material covering the orifice and is configured to move away under the pressure of the product in order to expose the orifice and allow the product to pass through it, and is configured to return to the closed position when the pressure is released. The closure member includes a sleeve, a first end of which is fastened to the body and a second end of which forms a free edge, said sleeve surrounds the body and is positioned over the orifice when said free edge has been turned up over the body. The body is rigid or semi-rigid.

  • Patent number: 6113002
    Abstract: A shower device having a flexible, flat jet or spray disk is created, in which at least one surface zone is curved outwards and on exceeding a specific pressing in force (E) exerted thereon springs round suddenly with the curvature inwards into a space located behind it and automatically springs back to the starting position when the force is relieved. As a result of the springing or springing round, it is possible to detach lime deposits from the jet disk.

  • Patent number: 5868325
    Abstract: This invention teaches a slidably attaching water flow limiting device which utilizes elastic and frictional forces to apply a force holding the flow limiting device onto a faucet such that these forces are exceeded at excess flow into the interior chamber of the water limiting device causing it to blow off the faucet. The water flow limiting device through a shaped hole restricted in area also provides a cleaning jet which makes the reduced flow effective for cleansing purposes despite the reduced flow rate.

    Abstract: A fuel-injection nozzle for internal combustion engines having plurality of lip elements on a nozzle tube, the edges are adjacent to each other. The lip elements form an obtuse cone and are held together under a high pre-stressing pressure by a clamping sleeve and an end cap. Pressure build-up in the interior chamber of the nozzle tube elastically expands the lip edges, in which case gaps are created, which form flat spray streams through which fuel is sprayed into the combustion chamber of the engine. When the fuel pressure in the interior chamber subsides the lip edges close to prevent any dirt from entering the slits.

    Abstract: A metal spraying device of the kind in which two wires are fed along convergent guide ducts, and an electric potential is established between the wires, so that an electric arc is produced between the terminal ends of the wires. A jet of air is blown across the arc, removing metal from the ends of the wires in the form of minute droplets, the jet of air being directed against a workpiece to be sprayed with a metallic coating. The metal spraying device comprises a head made of insulating material (e.g. ceramics material), the head being provided with passages forming the guide ducts for the wires and for the jet of air. In this manner, the wires may be guided more accurately to the arcing zone, and turbulence in the jet of air may be minimized, producing an overall improvement in the quality of the spray which may be achieved.
