This relates to an injection nozzle which includes a nozzle body having at one end thereof an inlet channel which is connected to an annular spinning chamber which is connected to the inlet channel by means of spin channels directed tangentially into the spinning chamber, and an exhaust orifice. The exhaust orifice is formed in a closure plate which cooperates with a core of the nozzle body disposed within the general confines of the annular spinning chamber to define a very narrow gap through which injected liquids flowing from the spinning chamber must pass in order to flow into the discharge orifice. The cross section of the exhaust orifice is materially greater than the cross section of the gap, thereby providing a much greater ratio of the smallest amount of liquid which may possibly be injected to the largest amount.
Injection nozzle for liquid media, with a nozzle body with an inlet duct and swirl ducts connected thereto and tangentially directed into a turbulence space, as well as with a return duct, whereby the turbulence space is substantially formed by an annular groove in the face side of the nozzle on the outlet side. There is a cover plate fastened thereon and provided with a central outlet opening, and the cover plate forms with the nozzle core a disk-shaped narrow gap. Thus, the nozzle body has in its face surface on the outlet side a central depression for receiving and locking into place the cover plate, whose diameter is smaller than the diameter of the nozzle body. The depth of the depression is smaller than the thickness of the cover plate, and the cover plate is seated on a collar of the nozzle casing enclosing the nozzle body.
A silicon valve for controlling the flow of a fluid includes two generally planar silicon members. One has an orifice for passing the fluid and the other has a relatively moveable surface to selectively open and close the orifice thereby controlling the flow of fluid through the orifice.
4227650 - Fluid dispenser and nozzle structure - Owned by Ethyl Products Company (Richmond, VA) [*] Notice:The portion of the term of this patent subsequent to July 17, 1996 has been disclaimed.
A fluid pump dispenser includes a nozzle structure having a flexible member which functions as an outlet check valve and O-ring seal, and which cooperates with a threaded nozzle cap to vary the discharge pattern of the dispenser responsive to twisting adjustment of the cap. Fluid is discharged through the nozzle structure by actuating a trigger to reduce the volume of a pump chamber in communication with the outlet check valve. The volume of the pump chamber may be reduced by operating a piston within the chamber or by flexing a wall of a tubular member having an open end in communication with the outlet valve.
The fuel injector nozzle injects fuel into the runner in a direction that may be either parallel or non-parallel to the co-axis of the fuel injector and its mounting socket, and the nozzle orifice from which the fuel is injected is disposed beyond an antechamber of the mounting socket so as to lie within the runner, hence injecting the fuel from the orifice at a location that does not lie within the antechamber of the mounting socket.
