Regulator Valve; Stator Reaction Hydraulic Pressure Control - Honda Prelude 1993 Service Manual

Rogulator Valve
The regulstor valv8 maintains a constant hydraulic pressure sent trom the oil pump to th€ hydrsulic control svstem, while also
turnishing oilto the lubricsting system and torque convarter.
Oil flows through B and B', The oilwhich enters through B flows through ths vslve orifice to A, pushing tho regulator valve to
the right. According to the level ot hydraulic pressure through B, the poshion ot the valve changes, and the smount of th€ oil
through B'from D also changes. This operation is conttnued, maintaining line prossure.

Stator Roaction Hydtaulc P1!ssur6 Control
Hydraulic prossuro increase according to torque is performod by the regulator valve using stator torqus reaction. The stator
shEft is spllned in the ststor, and hs arm end contacts the ragulator spring cap. wh€n the car is acc€lerEting or climbing (Torque
Converter Range), stator to.que reaction acts on the stator shaft, snd the stator arm pushes the r€gulsto; spring cap in the -)
direction in proportion to the reaction. The stator roaction spring compressos, and the regulator valve movss to increase the
regulated control pressure or line pr€ssure. Line prgssure is maximum when the stStor reaction is maximum.
