摘要： A compressor deicing system having an intercooler deicer valve and an after cooler deicer valve for selectively open and closing the first stage unloader and the second stage unloader so that high temperature air will deice the intercooler and aftercooler. When the first stage unloader is closed and the second stage unloader is open, the first stage temperatures will increase and the resulting high-temperature first stage air will thaw any ice accumulated in the intercooler. When the first stage unloader is open and the second stage unloader is closed, the second stage temperatures will increase and the resulting high-temperature second stage air will thaw any ice accumulated in the aftercooler.

摘要： A pneumatically piloted retainer valve for bottling brake cylinder pressure that can be set and released in response to changes in the brake pipe pressure. Pneumatically piloted retainer valve provides a brake cylinder pressure retaining function that bottles applied brake cylinder pressure in the brake cylinder when brake pipe pressure is less than a predetermined cut-in pressure. Pneumatically piloted retainer valve includes a retainer valve movable between a reset position, where brake cylinder pressure is in communication with exhaust and a bottle position, wherein brake cylinder pressure is isolated from exhaust. A retainer pilot control valve provides for piloting of the retainer valve in response to a predetermined reduction or threshold increase in brake pipe pressure.

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 during normal operations and selectively opens and closes certain of the valves when the temperature falls below a predetermined threshold to enter a safe mode that avoids freezing of the valves during operation. If an exhaust valve is open when safe mode is entered, the corresponding inlet valve is closed, both of the exhaust valves are closed, and the other inlet valve if opened. If an exhaust valve is not open, both inlet valves are opened and both exhaust valves are closed.

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 slack adjuster that is protected against environmental contaminants via a series of holes positioned circumferentially around each end and covered by a sleeve having a slot is aligned with one of the series of holes while covering the remaining holes. The sleeve protects against infiltration of contaminants at the ends of the slack adjuster and allows any contaminants that do infiltrate the slack adjuster to be expelled through the aligned hole and slot. The central portion of the slack adjuster may also be protected by including a series of circumferential holes that are selectively covered by a sleeve having a drain positioned to align with the lowest holes while covering the remaining holes.

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 resulted in 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： A control system for an air dryer that switches the flow and counter flow of air through each of two desiccant towers in response to a drying cycle period that is proportional to the saturation partial pressure of water vapor in the inlet air stream as determined by the temperature of the stream of air in the inlet of the air dryer. The system may also include a proximity sensor positioned in the back flow check valve between the first main reservoir and the second main reservoir to further adjust the regeneration cycle period according to the flow rate through the air dryer.
