    摘要： A high flow calibration test point has entry (16), inlet (24), and outlet (26) ports and a spring-biased plunger (40) that in one position provides communication between the entry port (16) and both the inlet and outlet ports, in another position provides communication between the entry port (16) only with the outlet port (26), and in yet another position allows communication only between the inlet (24) and outlet (26) ports.

    摘要： A pneumatic emergency brake release timer comprises a high capacity transfer valve, a timing reservoir in communication with the pilot port of the high capacity transfer valve (50), the check valve (64) and choke circuit (62) providing parallel connections between the main source of pressure and the reservoir through a check valve and opposite flow through a dissipating choke. A pneumatic relay valve controls the pressure to the brake cylinders. The high capacity transfer valve (50) can select a pilot pressure (48) to the pneumatic relay valve from two different pressure sources : a controlled pressure and an emergency pressure. Normally a controlled pressure is selected, e.g. a modulated pressure for wheel slip control. In the case of emergency braking, the timing reservoir (54) maintains the high capacity transfer valve (50) during a present time in a position wherein the controlled pressure is still selected. Thereafter, the emergency pressure is selected, thereby bypassing the pressure controller (44). The advantage is that wheel slip control is still possible during emergency braking for a present time, using pneumatic elements only.

    摘要： A pneumatic emergency brake assurance module comprises a high capacity transfer valve connected in a first position to the output of the variable load relay valve and in a second position connected to a source of emergency braking air pressure. A timing reservoir is in communication with the pilot port of the high capacity transfer valve. A check valve/choke circuit provides parallel connections between a double check valve and the output of the variable load relay valve such that flow from the variable load relay valve passes through a charging choke and opposite flow to the variable load relay valves passes through a dissipation choke.
