Ein Geschirrspüler umfasst einen Spülraum, in dem wenigstens ein Sprüharm (V) drehbar gelagert ist, an dem mehrere Düsen (5, 6) zum Sprühen von Spülflüssigkeit vorgesehen sind, die über eine Pumpe mit Spülflüssigkeit versorgt werden. Innerhalb des Sprüharmes ist von mindestens einer Düse (5) ein Strömungshindernis (8') zur Veränderung der Geometrie des Sprühstrahles vorgesehen. Dadurch kann das Sprühbild an der Düse individuell angepasst werden.

A liquid atomizer comprises a casing (1) provided with at least one supply channel (2) and an outlet slotted passage (3) with an open end part (4). The supply channel (2) is communicating with the slotted passage (3) on the side of its closed end part (5) and is arranged at an angle to a plane of symmetry of the slotted passage. The maximal cross-sectional size of an outlet aperture (9) of the supply channel (2) and a gap between walls (8) of the slotted passage (3) are selected on the determined conditions. The side walls (8) of the slotted passage (3) may be arranged in parallel with each other. The supply channels (2) may comprise closed cavities formed as branches leading from the channel zone where the supply channel (2) is joined to the outlet slotted passage (3). A high-velocity wide-span spatially homogeneous flat jet of finely dispersed liquid droplets is generated at the outlet of the slotted passage (3).

A spray nozzle for directing a wide lateral spray curtain with substantially uniform liquid distribution throughout the length of the spray curtain is provided. The nozzle includes a nozzle body defining an elongated internal flow passage. The nozzle body includes an inlet end for connection to a pressurized liquid supply, a downstream end wall and a side wall. A discharge orifice is provided in the side wall of the nozzle body between the inlet end and the downstream end wall. The discharge orifice communicates with the internal flow passage of the nozzle body. The discharge orifice has a generally inverted teardrop configuration comprising a relatively larger area upper portion and a relatively smaller area lower portion arranged below the upper portion.

A fire fighting nozzle for extinguishing industrial scale fires including improved automatic pressure regulating features, enhanced educting features having central (110) and peripheral channeling (94) for foam concentrate, combined with a capacity to throw dry chemicals. The improved pressure regulating features include a spring (50) loaded double acting baffle (13), that is positioned by fire fighting fluid in communication with a hydraulic chamber, the hydraulic chamber is preferably controlled by a relief valve (42).
摘要:
Spray nozzle for a spray boom to be fixed to a crop protection machine or the like. The spray nozzle is fixed on a supply line for spraying a fluid. The spray nozzle consists of a spray nozzle holder and a spray nozzle head. The passage of the inflow aperture to the outflow channel is regulated by means of an electromagnetic coil. Each spray nozzle holder can be controlled individually in a very accurate manner by means of such an electromagnetic shut-off valve situated in the spray nozzle holder. Connection between electric coil and spray nozzle holder is achieved by means of a connecting piece.

A nozzle assembly with a self-cleaning face is provided, having a nozzle body with a liquid flow path defined therethrough with an inlet and a spray outlet. The nozzle body is mounted in a carrier body, and an annular gas flow channel is located about the nozzle body with a gas discharge outlet defined around the spray outlet. A porous surface is located about the annular gas flow channel at the gas discharge outlet. A radiused surface is formed in the carrier body at the air discharge outlet. A pathway is in communication with the porous surface and adapted to provide a low velocity fluid discharge from the porous surface. A spray device and method are also provided using the nozzle assembly with the self-cleaning face. An adaptor for retrofitting an existing nozzle is also provided.

摘要:
A piezoelectric ejector device is provided which is designed to minimize the intake of air into the device upon actuation by providing for laminar flow of the fluid. In an ejector mechanism that includes a generator plate and a piezoelectric actuator operable to directly or indirectly oscillate the generator plate, at a frequency to generate a directed stream of droplets of fluid, the generator plate includes a fluid facing surface, a droplet ejection surface, and a plurality of holes formed through its thickness between the surfaces. The plurality of holes are configured so as to minimize airflow through the plurality of openings from the droplet ejection surface to the fluid facing surface during generation of the directed stream of droplets by configuring the shape of the holes to minimize turbulence.
