This is a still representation
and possibly also a low-resolution image of a fully animated pump.
|
|
|
This type of gear pump has two lobes on each shaft. The lobes nearly touch
each other in the center forming a fairly tight seal. |
|
They also nearly touch the casing and when they revolve they carry fluid
around the outer edge to the outlet, at the top in this drawing. |
|
This type of gear pump, or a three-lobe version,
is often used as a supercharger for diesel engines, forcing air (not liquid)
into the power cylinder. |
