  • Publication number: 20040050976
    Abstract: In a fuel injection valve including a flat fuel diffusion chamber provided between a valve seat member and an injector plate to widen radially outwards from an outer end edge of a valve seat bore, an annular step is formed on a ceiling surface of the fuel diffusion chamber so that a level of the ceiling surface is gradually lowered radially outwards, and fuel injection orifices are disposed immediately below the step and at a distance from an inner peripheral wall of the fuel diffusion chamber. Thus, a fuel spread radially in the fuel diffusion chamber is allowed to collide with the annular step, leading to an enhancement in fuel diffusing effect, so that it is possible to further promote the atomization of the fuel injected from the fuel injection orifices and to form more stable fuel spray forms.

  • Patent number: 6622944
    Abstract: A two phase fuel oil atomizer utilizing a secondary media such as high pressure steam or air to assist in the atomization of heavy fuel oil, while reducing NOx and other polluting emissions. The fuel oil atomizer comprises a mixing plate and a sprayer plate which are configured to discharge atomized fuel oil at varying spray angles in order to provide staging of the atomized fuel as it exits the sprayer plate with the surrounding combustion chamber air to provide a fuel/air ratio that is appropriately rich and lean in order to allow lower flame temperatures. NOx generation is accordingly reduced at the lower flame temperatures. With atomized fuel droplet size small enough to enable rapid fuel evaporation and complete combustion, low CO, opacity and particulate generation are achieved with minimum excess oxygen.

  • Patent number: 6076517
    Abstract: The invention is directed to an arrangement for adjusting a pressure-fluctuation free supply of gas and for controlling an operating pressure of an air/gas mixture to a radiation-gas burner of a gas cooking apparatus. The radiation-gas burner has a burner chamber and is mounted in a housing below a cover plate. The arrangement includes a gas supply conduit connectable to a gas source for receiving the gas and a pressure controller is mounted in the gas supply conduit for controlling the pressure of the gas to a constant operating pressure of at least 2.5 mbar above atmospheric pressure. A control unit is connected to the pressure controller for receiving the pressure-controlled gas and for metering the gas to the radiation-gas burner. The control unit includes a valve block having at least one exchangeable nozzle adapted to the type of gas from the gas source and a feed conduit has a clear cross-sectional area and communicates with the burner chamber. The feed conduit has an inlet opening adjacent the nozzle.

  • Patent number: 6053431
    Abstract: A liquid atomizer for, e.g., fuel, comprises a tube having an opening for receiving pressurized liquid flow. The tube has a closed end, a wall, and a plurality of bores in the wall. The bores are disposed in consecutive circumferential rows, and are oriented at an acute angle .alpha. with respect to a radius of the tube and at an acute angle .beta. with respect to a longitudinal axis of the said tube. A shell having a discharge end with a discharge orifice encircles a portion of length of the tube, including the closed end of the tube. The shell forms an annular chamber around the tube end and an end chamber between the closed tube end and the shell discharge end. Liquid under pressure entering the tube opening is directed outwardly through the wall bores into the annular chamber, into the end chamber, and out through the discharge orifice for introduction, for example, into a combustor.

  • Patent number: 6015101
    Abstract: A gas burner system which can be used in a conveyor-type oven has a burner tube (4) extending across the conveyor. Gas is burnt through a slot (8) along the tube to give a ribbon flame. The tube (4) is divided into separate compartments (15-19) which connect with different lengths of the slot (8). Combustible gas is fed under independent control to the different compartments (15-19), and the slot lengths are adjustable. The slot lengths consist of short edge-region slots and multiple, longer central region slots.

  • Patent number: 5957388
    Abstract: The invention relates to a container for flowable cleaner products, particularly for liquid thixotropic WC bowl cleaners of which the thixotropic properties cause the liquid WC bowl cleaner to adhere to vertical surface. It is the object of the invention to provide a container having a spray head which causes the flowable cleaner product, and particularly the afore-said WC bowl cleaner, to be distributed in an optimum manner and which at the same time can be sealed and closed in a child-proof manner. To this end, the container is equipped with a spray head which consists of a cylinder-like basic body and of a mandrel-like body having a plurality of spray orifices, with the geometry and the relative arrangement of the cylinder-like and mandrel-like bodies being such as to enable the required optimum distribution to be obtained, with a special design of the closure cap providing for child-proof sealing and a releasable engagement thereof with the spray head.

  • Patent number: 5918816
    Abstract: A multifunction hand shower can be used in at least two modes of operation: in the first of these modes of operation, the shower jets emerge from the shower base (3) in a constant stream at relatively high speed and with a small cross-section ("hard jet mode") and in the second mode of operation they emerge at high speed and with a relatively small cross-section, but are intermittently interrupted ("pulse jet mode"). The periodic interruption of the "pulse jets" is ensured by a pulse wheel (23) which is housed in a circular chamber (20) in the housing (1) in such a way that it can rotate. In the "hard jet mode", the rotation of the pulse wheel (23) is interrupted, by a stop (45), in a quite specific angular position which allows the hard jets to emerge from the shower base (3) in a constant stream. To change over to "pulse jet mode", the stop (45) is moved out of the path of movement of a stop (28) which is connected to the pulse wheel (23) such that the pulse wheel (23) is now able to rotate freely.
