The oil pump is driven by a motor via a transmission shaft from the primary pulley.
The pump is an external gearpump. The oil flow is delivered from the pump and regulated by the hydraulic valve. This serves to control the primary and secondary pulley positions and to lubricate all components.
The oil pressure varies depending on the driving conditions, from 12 to 35 kg/cm², as shown in the graph below.
