SKID CONTROL VALVE ASSEMBLY

摘要

A skid control valve assembly including a force motor assembly for controlling the skidding of a vehicle under braked conditions, the force motor assembly being provided with variable duty cycle pulses from a control system which provides a signal wave form to control the position of the fluid pressure controlling device in one of three conditions; the first being "dump" mode of operation wherein the force motor is controlled to preclude braking pressure from being supplied to the wheels of the vehicle, the "hold" mode of operation wherein the braking force present at the time the system goes into the hold mode of operation is maintained, and the "return" mode of operation wherein braking pressure is returned to the vehicle wheels.
