Injector

3D Model

These are: 1) There are three connections. One for the high pressure (HP) motive, one for the low pressure (LP) suction entrained and one for the medium pressure discharge. 2) The suction (in this case gas) comes in at the side. 3) There is a nozzle for converting the pressure energy of the high pressure motive into kinetic energy.
