This is a still representation
and possibly also a low-resolution image of a fully animated pump.
|
|
|
This pump consists of two rotating gears; an Internal Gear with the teeth
on the outside, and an External gear with the teeth on the inside. The
External Gear is larger and has more teeth, but the teeth are the same
size. |
|
As the teeth separate (lower left side in this drawing) they pass over
the intake hole (shown behind the gears in black on the left). They "suck"
in fluid, then the gears are separated by a Crescent Seal (shown in brown.) |
|
When the teeth start to come together again (upper right here) they squeeze
the fluid through the outlet hole (shown in black at the top center of
this drawing.) |
|
Normally the inner gear is attached to a drive shaft and the outer gear
is turned by the inner gear at the point of contact (upper left area of
this drawing.) |
