Shift Valve Holding Pressure

| 1 - HOLDING PRESSURE SHIFT VALVE |
The holding pressure shift valve (1) is actuated by the pressures present at the end face in the actuators and a spring. It assigns the working pressure (p-A) to the actuator with the higher pressure (taking into account the spring force and the effective surface 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). See Fig 1.
