摘要： An air dryer system for a locomotive having optimized purge air control over a twin tower desiccant-type air dryer. The computer controlled locomotive brake system is used to determine when the air dryer is being used and approximately how much air flow has actually passed through the active tower of the dryer using the air consumption state, the change of pressure in the second main reservoir, the air compressor on/off state, the total accumulated time of air flow since last purge cycle, and/or the calculated air flow through the air dryer since the last purge cycle. When the actual air flow reaches the capacity of the active tower of the air dryer, the computer controlled locomotive brake system commands the air dryer to perform a purge cycle. The system thus maximizes the use of each tower in the air dryer rather than switching according to a preset time period.

摘要： A brake cylinder having a filament wound composite pressure cylinder and a composite plastic non-pressure head. The pressure cylinder and non-pressure head are secured together by a pair of mating flanges and a V-shaped band securely attached over the flanges. The band has a gap that is easily adjustable to position the gap at the lowest point and be in alignment with a series of radially extending grooves in the flange of the non-pressure head, thereby ensuring proper drainage. The non-pressure head may include an integrally formed an opening with a bearing surface for a piston rod, a seat for a piston return spring, a scraper for a piston rod, and a series of internal ribs that provide for structural support and act as stop against a piston overtravel.

摘要： A brake cylinder maintaining system produces a brake cylinder reference pressure based on the difference between the brake pipe pressure and the auxiliary reservoir pressure and then feeds that pressure to a choke and a volume so that the ratio of the reference area of the choke to the volume of stored brake cylinder reference pressure is substantively equal to the ratio of a brake cylinder charging valve area to the brake cylinder volume. The resulting reference pressure may be used to adjust brake cylinder pressure by providing the reference pressure to a standard quick service limiting valve or to a relay that can selectively charge or exhaust the brake cylinder.

摘要： A branch pipe tee for a rail car having a length that is below standard. The branch pipe tee has a standard mount for connecting to the brake pipe and branch pipe as well as integral volume that compensates for the reduced brake pipe length of the rail car. The integral volume is dimensioned to make the effective brake pipe length of rail car fall within standard ranges so that the braking system of the rail car can perform normally and avoid the need for additional equipment to compensate for the length of the rail car.

摘要： A system for identifying whether the braking system of a train is functioning properly such as during a train terminal test. A monitor on a rail car is used to detect abnormalities in the braking system and can report problems to a handheld terminal or a central controller in the locomotive. The monitor has a pressure sensor for measuring brake pipe pressure, auxiliary reservoir pressure, emergency reservoir pressure, and brake cylinder pressure at the rail car. The monitor also has a controller that can calculate whether brake pipe reduction resulting the appropriate amount of brake cylinder pressure. The monitor can then provide the results locally via a visual indicator or remotely to a handheld terminal used by a train inspector or the controller in the locomotive. Testing data over time may be stored for future reference or transmitted remotely to assist with maintenance and service scheduling.

摘要： A computer controlled locomotive brake (CCB) configured for setting and releasing the retainer valves of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the retainer valve release pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all retainer valves are released and the train has sufficient braking system recharge to safely control movement of the train.

摘要： An air dryer for a locomotive air supply system that includes a controller programmed to initiate a sleep mode that inhibits the air dryer and de-energizes all valves. The controller determines when it is appropriate to enter into sleep mode based on various conditions of the locomotive air supply system. More specifically, the controller is programmed to calculate whether the air dryer should be placed into sleep mode based on operational characteristics of the locomotive air supply system that are indicative that the system has been idled. The initiation of an air dryer sleep mode by the controller prevents undesirable venting of air from the air supply system and unnecessary usage of locomotive battery power.

摘要： An air dryer having a heater element associated with its valves to prevent freezing at cold temperatures. The air dryer includes a temperature sensor and an electronic controller that reads the temperature sensor and inhibits actuation of the valves whenever the temperature of valves is below freezing or a predetermined temperature that indicates a risk for freezing until the valves have been sufficiently warmed by the heater to avoid freezing during operation.

摘要： A railway air dryer that switches the flow and counter flow of air through each of two desiccant towers in response to the actual humidity of air being dried by the air dryer. The air dryer includes a humidity sensor, a temperature sensor in the outlet air, and a temperature sensor in the inlet air stream to determine when to initiate the regeneration of the desiccant. The air dryer system is generally specified to provide some minimum drying performance, for example 40° C. dew point suppression.
