A device which expels cartridges or fired cases from a firearm.

See board extractor.

The mechanism on shotguns by which spent shot cases are automatically ejected from the gun when it is opened after firing.

a mechanism in a firearm that ejects the empty shell case after firing

a feature that will throw the empty hull clear of the barrels

A device for expelling a fired cartridge case from a firearm.

Part of a rifle or gun which discharges the case from the breech.

A part of the action of a firearm that throws the empty cartridge clear of the weapon. Single action revolvers usually have an ejector/extractor rod that is used to push the cartridge back through the loading port. Double action revolvers usually have a star built into the end of the chamber that ejects/extracts all cartridges at the same time.

Mechanical device used to eject empty cartridges from chamber(s).

That part of a semi-auto that causes an empty case to be forcefully driven from the gun as part of the recoil cycle.

The part of a semi-automatic responsible for tossing the empty case out of the ejection port.

The mechanism which expels the cartridge or case from the breech of the gun.

On breech loading small arms, a device that removes the empty cartridge case after firing. Various methods have been devised to perform this function. On hinge frame guns the ejector is a spring attached to the extractor that causes a violent rearward snap of the extractor when the barrel is positioned to permit the cartridge to be thrown clear of the weapon. More often the ejector is a small protuberance within the receiver against which the case, having been extracted, strikes and is thrown clear. On hand ejector weapons, manual pressure on the extractor moves the cartridge case rearward to clear the chamber. In certain rifles, like the Garand, the ejector occurs in the bolt face as a spring loaded pin constantly exerting pressure on the case head. Opening the action allows instant ejection. In certain automatic pistols and foreign weapons the cartridge is ejected by the striker pin acting near the close of the rearward stroke of the firing cycle.

A mechanism for removing a part from a die. Also called kicker or knock-out.

The part that expels the empty cartridge case from the receiver of a weapon; it maybe fixed, spring-loaded, or movable.

A device for utilizing the momentum of a jet of steam or air under pressure to lift a liquid or a finely divided solid.

jet portion of centrifugal jet pump design.

A siphon device used to fill an engine's tank when the water source is below or beyond the engine's drafting capability.

Most steam engines used for passenger and mainline work generally, had vacuum brakes. The vacuum was created by blowing steam through a series of cones. The larger cone (large ejector) was used to create the vacuum before the locomotive/train could move. A smaller ejector could be used to maintain the vacuum while running.

A device which uses high fluid velocity, such as a venturi, to create low pressure or vacuum at its throat to draw in fluid from another source.

A device used to disperse a chemical solution into water being treated.

A device which utilizes the kinetic energy in a jet of water or other fluid to remove a fluid or fluent material from tanks or hoppers.
