ABSTRACT:
A wheel slip assurance module comprises a device for disabling the wheel slip valve, a timing reservoir in communication with the disabling device, and a check valve and choke circuit providing parallel connections between the output of the wheel slip valve and the timing reservoir having a first connection path comprising a check valve and charging choke and a second connection path comprising a dissipating choke such that flow from the output of the wheel slip valve passes through the check valve and charging choke to charge the reservoir when the brake cylinders are pressurized and opposite flow passes through the dissipating choke allowing the reservoir to discharge when the brake cylinders are exhausted.
