Abstract: A nozzle closing valve, particularly for a pressure atomizer nozzle of an oil burner, comprises an inlet side with an inlet passage, an outlet side with an outlet passage, a valve seat located between the inlet passage and the outlet passage, as well as a shutoff member. The shutoff member is sealingly pressed onto the valve seat by way of a first spring located behind the shutoff member and rises from the valve seat counter to the force of the first spring when a predetermined pressure is reached in the inlet passage. A maximum sealing action with easy manufacturability and a particularly compact structure are achieved in that the shutoff member is constructed as a membrane; the first spring has an essentially linear spring characteristic; the first spring is housed in a spring chamber, which is constructed as a space open on one side and whose sole opening is sealingly closed by the membrane; and the first spring and the spring chamber are located on the inlet side of the nozzle closing valve.

Removably attached to the annular wall is a circular disk having a planar surface terminating at a ring such that the ring projects about perpendicularly from the planar surface. The circular disk has a coupling projecting about perpendicularly around a center point of the planar surface.

Abstract: An agricultural spray implement includes a plurality of removable valve/filter/nozzle cartridges. Each removable cartridge has a single housing that retains a magnetized filter, a high speed solenoid valve, and a spray nozzle. In the event the system filter of the spray implement is removed, fine particles which otherwise might clog the solenoid valves are stopped from entering the solenoid valves by the magnetized filters of the valve/filter/nozzle cartridges. Each cartridge has a clean-out purge valve so that its magnetized filter can be unclogged without removal of the magnetized filter from the cartridge housing. A light emitting diode of the cartridge provides a visual indication that the cartridge is dispensing agricultural liquid. The light emitting diode is turned on when the solenoid valve is controlled to be open.

Abstract: A recirculating paint supply system supplies single or multiple paint coatings to paint spray stations arranged in parallel or series relation, each station including manually operated flexible monoline and coaxial conduits to supply paint to an improved spray gun. In one aspect of the invention, the improved spray gun is comprised of a polymeric material to reduce the overall weight of the spray gun thereby reducing operating fatigue and ailments caused by the use of conventional spray guns. In another aspect, the improved spray gun includes larger air passages which provides for a greater volume of air to pass through the spray gun, thereby providing increased atomization of the liquid coating composition. Thus, the reduced weight, as well as the increased atomization, increases the overall finish quality of the object being painted.

Using this arrangement, a cohesive tulip-shaped jet lamella can be produced which thins out in the downstream direction and then disintegrates into tiny droplets. As a consequence, the exhaust emission of an internal combustion engine can be further reduced and likewise a reduction of the fuel consumption can be achieved.The nozzle plate is suited particularly for injection valves in fuel injection systems of internal combustion engines with externally supplied ignition which compress the mixture.

Abstract: An atomizing sieve of a fuel injection valve having a dish-like concavely cambered form is provided downstream of at least one spray orifice of the fuel injection valve, as seen in the direction of flow of fuel. The atomizing sieve is cast with an outer circumferential region in a protective cap provided at the downstream end of the fuel injection valve. For protection against mechanical effects, protective prongs of the protective cap project further downstream than the lowest region of the atomizing sieve. When the fuel is being injected, a part quantity collects in this lowest region and represents a comparatively static liquid quantity which new fuel then strikes. This arrangement allows an ideal break-up of the fuel into very small droplets. The atomizing sieve also forms a protective shield against icing-up, plugging and settlement of chemical substances within the fuel injection valve.

Abstract: A spray nozzle in which a nozzle body is formed with an elongated chamber having an air inlet port communicating with the side of the chamber, a liquid inlet port communicating with one end of the chamber, and a nozzle tip communicating with the opposite end of the chamber. The spray nozzle may be operated in a hydraulic or non-air assisted mode and with a relatively high flow rate by closing off the air inlet port and causing liquid to stream directly from the liquid inlet port to the nozzle tip. The nozzle also may be converted to an air assisted mode in which a stream of pressurized air is injected into the air inlet port and impinges transversely against the liquid stream to preliminarily break up or preatomize the liquid before the liquid is discharged from the nozzle tip. The conversion is effected by placing into the nozzle body an insert for reducing the flow rate of the liquid stream and for causing the air and liquid streams to interact to effect preatomization of the liquid.
