In adjustable engine oil pumps, 3/2 or 4/3 proportional valves by ETO ensure variable adjustment of the output/pump capacity to the speed.
As 3/2-On/Off solenoid valves, they are used in the two-stage switchable oil pump, ensuring ideal adjustment of the pump capacity to two different engine speed ranges.
This variable control means that we are able to ensure a sustainable reduction of CO2 consumption.
