摘要： A pneumatic door control equipped with a door control valve for operating a door drive to an open or a closed position. The door control valve has an opening and a closing solenoid-operated pilot valve and an opening and closing spool valve, each operable to a passage or a vent position. A shuttle valve is part of the control valve and works in conjunction with an operator-controlled emergency valve to vent both spool valves simultaneously. A differential pressure switch is connected to the door drive to sense abnormal pressure expended in a door-opening or closing movement. Such an occurrence will output a signal to an electronic switching device which also monitors, via limit switches, whether a door is fully opened or fully closed. If excess pressure occurs during a door-closing movement, the switching device will trigger the control valve to reverse to the opening position. If excess pressure occurs during an opening movement, the switching device triggers both solenoid-operated pilot valves simultaneously. The control valve has a non-return valve which recognizes the dual triggering condition and outputs to the shuttle valve so that the two spool valves can be vented simultaneously. A throttle valve is disposed between the emergency valve and control valve for restricting the flow of pressurized air following an emergency condition.

摘要： An electropneumatic door valve for use with pneumatic door operations as are used on mass transit vehicles. The single valve housing arrangement provides either a through passageway or a throttled passageway for pressurizing the opening or closing chamber of a pneumatic door drive unit. Provisions are also made to allow automatic reversal should the door become wedged, and to allow manual override should that operation be desired. Electrical pulses initiated by the vehicle operator trigger one of two solenoid valves which direct one of two operating pistons into a position to dictate which passageway will be established. Three vent passageways are provided to exhaust compressed air from any of the chambers which had been charged during a previous door operation.

摘要： Pressurization of closing and opening chambers of a door operator is controlled by first and second magnet valves coupled to the source of air. These valves are alternately energized by a switching network, e.g., a flip-flop, when sequentially actuated to close and open the door. The second magnet valve is biased to its vent position but the first valve is operated to its vent position by air through a double check valve when the second magnet valve is energized. Emergency and choke valves are inserted in series in the air supply to the magnet valves and normally pass air without restriction. Operation of the emergency valve, e.g., door blocked, shuts off air from the magnet valves and diverts that air to inhibit all output from the switching network and, through the check valve in opposite position, to operate the first magnet valve to vent position. Door operation is halted in position. Shortly the choke valve, because of the venting of both magnet valves, shifts from non-choke to choke position to restrict flow of air when the emergency valve is restored to normal. Restoration of door operation, by switch network actuation at the end of the emergency, is thus initially at a restricted rate.
摘要翻译：门操作者的关闭和打开室的加压由联接到空气源的第一和第二磁阀控制。当顺序地致动以闭合和打开门时，这些阀由切换网络例如触发器交替地激励。第二磁阀被偏置到其排气位置，但是当第二磁阀被通电时，第一阀通过双重止回阀被空气操作到其排气位置。紧急和阻流阀串联插入到电磁阀的空气中，并且通常通过空气而不受限制。紧急阀的操作，例如门被阻塞，关闭来自磁阀的空气并转移该空气以阻止所有来自开关网络的输出，并且通过相反位置的止回阀来操作第一磁阀以排气。门操作停止就位。由于两个磁阀的排气，阻塞阀不久就会从非扼流圈转到扼流位置，以限制紧急阀恢复正常时的空气流动。因此，通过在紧急情况结束时的开关网络启动来恢复门操作，因此首先受到限制。
