Operation of Hydraulic Pump
The hydraulic pump has two meshing gears (2), (3)
whose teeth run close to the casing (1). One gear is a
drive gear (2) which drives the driven gear (3).
When the drive gear is driven in the direction of the
arrow by the crankshaft, the gears trap oil between the
gear teeth and the casing. The trapped oil is carried
around to the outlet. The higher the engine speed, the
more the pump discharge.
