GF27.60-P-5135-04G Holding Pressure Shift Valve, Function
GF27.60-P-5135-04G Holding pressure shift valve, function
- TRANSMISSION 722.6
Operation
The holding pressure shift valve (28) is engaged by pressures in the shift elements acting on the front face and a spring. It assigns the working pressure (p-A) to the shift element with the higher pressure (taking into account the spring force and the effective area).
The other element of the shift group is then unpressurized. The valve switches over only during the shift phase and only at a certain pressure ratio between the overlap pressure (p-U) and the shift pressure (p-S).
