Now Playing: How an eccentric oil pump work

Description: The idea behind this pump is different pressure zones (or volume changes) In this pump there are only 2 moving parts, the red rotor which spins by the engine power (either by a little metal chain or sprockets), it moves the passive yellow rotor. This movement causes CONSTANT VOLUME CHANGES in certain areas of the pump. At the left you can see the empty space (which is shown as stripes) always expanding - exactly there you will find the oil entrance to the pump. On the right side you will see the space is constantly getting smaller - there is the oil exit pipe located. The oil is sucked-in on the left, it is then carried in the space between the two rotors, and then finally being squeezed out on the right side exit.
