Agent/instrument noun formed from the verb 'eject' with the productive suffix '-or', so the device sense is directly predictable.

Etymology

Ejector comes from the Latin parts e- 'out' and jacere 'to throw', so it means 'to throw out'. An ejector as a device is something that 'throws out' or pushes out liquid or parts, like a pump or the part of a gun that removes a shell.
