This is a still representation
and possibly also a low-resolution image of a fully animated pump.

|
A very common type of pump, this is one of many variations. |
|
Power steering units often rely on a vane pump to obtain the pressure needed
for the Power Cylinder. Automatic transmissions often use them too. |
|
The vanes are in slots in the rotor. When the rotor spins, centrifugal
force pushes the vanes out to touch the casing, where they trap and propel
fluid. Sometimes springs also push the vanes outward. |
|
When the vanes reach the return side they are pushed back into the rotor
by the casing. Fluid escapes through a channel or groove cut into the casing,
shown here on the lower right side in black. |
