A contrivance for forcing feed water into a steam boiler by the direct action of the steam upon the water. The water is driven into the boiler by the impulse of a jet of the steam which becomes condensed as soon as it strikes the stream of cold water it impels; -- also called Giffard's injector, from the inventor.

An apparatus for forcing water into a steam boiler by means of an enclosed jet or nozzle, through which the steam issues at a high velocity, drawing water through a suction pipe and carrying it along to the boiler in a feed pipe, where, because of its high velocity and force of impact, it is able to overcome the back pressure and enter the boiler.

The ion source and first stage of acceleration up to 1-2 MeV is the injector of a driver.

A device utilizing a steam jet to entrain and deliver feed water into a boiler.

Refers to the pump system (used in a fuel injection system) that squirts or injects a measured amount of gasoline into the intake manifold in the vicinity of the intake valve. In the diesel engine fuel is injected directly into the cylinder.

A system of orifices used to direct propellant to create mixing and fog production for combustion.

In a diesel engine, the unit that sprays fuel into the combustion chamber.

A mechanism for accurately injecting a predetermined amount of sample into the mobile phase stream. The injector can be a simple manual device, or a sophisticated autosampler that permits automated injections of many different samples for unattended operation.

One of the seven basic components of an HPLC system; allows a predetermined amount of sample to be introduced into the MOBILE PHASE flow path. The injector can be as simple as a manually-actuated valve for single injections, or it could be a completely automated instrument for unattended, multi-injection analyses.

System for introducing the sample or mobile phase into the column. May be either manual or automated. It is a good idea to filter the analyte to prevent the injector from clogging.
