Regulator Valve
The regulator valve has one function: to regulate or control hydraulic pressure in the transaxle. The pump supplies unregulated pressure to the regulator valve. The regulator valve controls, or limits, pump pressure. Regulated pressure is referred to as "line pressure." The regulator valve has a spring on one end that pushes the valve to the right. This closes a dump (vent) to lower pressure. Closing the dump will cause oil pressure to increase. Oil pressure on the opposite end of the valve pushes the valve to the left, opening the dump and lowering oil pressure. The result is spring tension working against oil pressure to keep or maintain the oil at specific pressures. Regulated pressure varies depending on the gear range the transaxle is operating in.
A system of sleeves and ports allows the regulator valve to work at one of three different predetermined pressure levels. The oil that is dumped by the regulator valve is directed back to the intake side of the oil pump.
