1994 HONDA INTEGRA drive shaft

Construetion
The pump is a vane-type incorporating a flow control valve (with an integrated relief valve) and is driven by a V-belt from
the crank pulley. The pump features 10 vanes, Each vane performs two intake/dischsrge operations for every rotation of
the rotor. This means that the hydraulic fluid pressure pulse becomes extremely small during discharge.
CAM RING
FLOW CONTBOL VALVE
DRIVE
Operation
The belt-driven pulley rotates the rotor through the drive shaft, As the rotor rotates, the hydraulic pressure is applied to
the vane chamber of the rotor and the vanes witl rotate while being pushed onto the inner circumference of the cam .ing.
The inner circumference of the cam ring has an extonded portion with respect to the center of the shaft. so the rollers
move downward in the axial direction as the carrier rotates. As a result of this roller movemsnt, the internal volume of the
vane chamber will change, resulting in fluid intake and discharge.
