Auxiliary Pump

The auxiliary pump is a gear type pump. The

working principle of a gear pump depends on the

meshing of two spur gears

and

. Oil is picked up

on the suction side of the pump by the gears and

carried round between the gear teeth and the pump

body. As the gears come into mesh the oil is forced

out through the outlet port.

Some oil is allowed to circulate behind the bearings

to hold them against the gears and minimise oil

slippage. Lubrication oil is drawn through the recess

and around the counter bore. The oil then flows

along the scrolled grooves

in the bushes, induced

by the viscous drag of the rotating shaft.
