A restricted opening through which the media must pass when flowing through the valve. The orifice is opened and closed to permit or stop flow. This is accomplished with a poppet, diaphragm or floating seal.
Generally, an opening in a dispensing closure or fitment from which the product is dispensed.
A small hole or vent such as the gas port in the barrel of a gas-operated firearm.
Orifice plate O-ring groove
Generally an opening. Used specifically to refer to the small holes in spinnerets through which the polymer flows in the manufacture of fibers.
The small burner part assembly (a gauged hole fitting) that must be changed out to accommodate either L.P. or natural gas.
The orifice is the opening found in a cap, spud, or some other type of device where gas flow is limited. Additionally, the orifice is where the flow of gas is discharged to the burner.
The entrance or outlet of a body cavity.
A hole or aperture without appreciable length, (depth). In most cases the technically correct term for the whole employed in inkjet printing systems. (see Nozzle)
A hole or aperture without appreciable length. In most cases this is the technically correct term for the hole employed in inkjet printing systems.
Discharge hole in a low pressure lateral or pressure manifold.
Opening in the zooid wall through which the lophophore and tentacles are exserted. In Cheilostomata, the primary orifice may be surrounded by a peristome; the opening at the upper end is then known as a secondary orifice. (Hayward & Ryland, 1979) Figures: Smittina, Hippoporina, Porina
An opening through which gas is discharged and whereby the flow of gas is limited and/or controlled.
An opening or hole; an inlet or outlet.
Latin orificium = opening.
The opening in the extruder die.
1) An opening with closed perimeter, usually sharp edged, and of regular form in a plate, wall, or partition through which water may flow, generally used for the purpose of measurement or control of water. 2) The end of a small tube, such as a Pitot tube, piezometer, etc.
an opening in a wall or plate.
A small opening through which refrigerant fluid flows.
A precisely formed hole in a plastic pipe or tube or in a small fitting (known as an emitter) plugged into plastic pipe through which water flows out in drops or a tiny stream.
The opening in an extrusion die through which the material is extruded.
An opening of a precise diameter which limits the flow through the opening. Examples: gas orifice regulates the amount of gas which can pass from a gas valve to a burner. Water orifice in a humidifier regulates how much water can flow through the humidifier.
A fixed opening, normally the inside diameter of a seat ring, through which fluid passes. The term can also refer to the inlet or outlet of a regulator or pilot valve. Also called a Port.
The opening in an orifice cap, orifice spud, or other device whereby the flow of gas is limited and through which the gas is discharged.
An opening in a plug, fitment, or dispensing cap through which the product is dispensed.
Opening; mouth of the ovule.
1. An opening through which something may pass. 2. Attachment to the nozzle on the hose of a plastering machine, of various shapes and sizes, which may be changed to help establish the pattern of the plaster as it is projected onto the surface being plastered. 3. The opening through which fuel is ejected into the burner unit of a furnace or boiler.
The hole in the end of a teat.
The opening in a cap, spud or other device whereby the flow of gas is limited and/or controlled and through which the gas is discharged to either a pilot burner or main burner.
an opening of a measured diameter that is used for measuring the flow of fluid through a pipe, the orifice must be of smaller diameter than the pipe diameter. It is drilled into an orifice plate held by an orifice fitting.
An opening to a cavity or tube
a small opening or passage
A closed perimeter opening of any size or shape with walls that extend from the front surface to the back surface of the material through which the opening extends and allows the flow of gas and liquids.
A small hole or opening in a valve, tube or pipe.
An opening or hole, especially in spray equipment.
opening through which lophophore and introvert are protruded.
opening in the end of the spindle shaft, through which the spun yarn passes
The opening in a cap, spud or other device whereby the flow of gas is limited, and through which the gas is discharged to the burner.Two types of orifices include main burner orifices and pilot burner orifices. Main burner orifice: either a plug or cap type.
opening having a closed perimeter through which a fluid may discharge. It may be open to the atmosphere, or it may be partially or completely submerged in the discharged fluid.
1. An opening, such as a hole or vent in something
An opening, usually one that can be constricted or closed by a control device.
The opening from the whirling chamber of a mechanical atomizer or the mixing chamber of a steam atomizer thru which the liquid fuel is discharged. (2) A calibrated opening in a plate, inserted in a gas stream for measuring the velocity of flow.
In industry, a plate with a calibrated hole drilled in it through which a liquid or gas flows. The pressure difference across the plate can be used to determine the flow
An opening in a tube designed to regulate the flow of a fluid.
The opening of a cavity or chamber.
