摘要： An electronic air charge controller for a tractor trailer vehicle air brake system includes a micro controller, a first pressure sensor interface coupled to the micro controller, a second pressure sensor interface coupled to the micro controller, and a vehicle control protocol interface coupled to the micro controller. The micro controller, in response to a signal received from the first pressure sensor interface indicative of an air supply recharge condition, a signal received from the second pressure sensor indicative of parking brake engagement condition, and a signal from the vehicle control protocol interface indicative of an engine start condition, supplies a maximum engine speed control signal to the vehicle control protocol interface. The time required to charge the air supply system to the required normal operating level is thereby minimized. In addition, a transmission sensor interface is preferably coupled to the micro controller. The micro controller does not generate the maximum engine speed control signal unless a signal supplied by the transmission sensor interface indicates that an automatic transmission is in park or a manual transmission is in neutral. Still further, to improve operating efficiency, a vehicle load condition signal is supplied by the vehicle control protocol interface to the micro controller. In response, the micro controller supplies a pause air compressor charging cycle signal or a pause air dryer recycle signal to the vehicle control protocol interface, if either the air compressor or air dryer is operating when a high load condition is encountered.
摘要翻译：一种用于拖拉机拖车车辆空气制动系统的电子空气充注控制器包括微控制器，耦合到微控制器的第一压力传感器接口，耦合到微控制器的第二压力传感器接口以及耦合到微控制器的车辆控制协议接口控制器。微控制器响应于从第一压力传感器接口接收的指示空气供应再充电状态的信号，从第二压力传感器接收的指示驻车制动器接合状况的信号，以及来自车辆控制协议接口的信号，发动机起动条件，向车辆控制协议接口提供最大的发动机转速控制信号。因此将空气供应系统充电至所需正常操作水平所需的时间最小化。此外，传输传感器接口优选地耦合到微控制器。除非由传动传感器接口提供的信号表示自动变速器处于驻车状态或手动变速器处于空档位置，否则微控制器不会产生最大发动机转速控制信号。此外，为了提高运行效率，车辆负载状态信号由车辆控制协议接口提供给微控制器。作为响应，如果空气压缩机或空气干燥器在遇到高负载条件时运行，微控制器将暂停空气压缩机充电循环信号或暂停空气干燥器再循环信号提供给车辆控制协议接口。

摘要： A compressed air system includes an air compressor the inlet of which is communicated to the vehicle engine turbocharger. The outlet of the air compressor is communicated through an air dryer to a storage reservoir. A governor is responsive to the pressure level in the reservoir to generate an unloading signal unloading the air compressor when the pressure in the reservoir attains a predetermined value. The unloading signal is also communicated through a control valve to purge the air dryer during compressor unloading. The control valve closes communication between the governor and the air dryer to trap a predetermined pressure level in the purge volume of the air dryer to prevent the air dryer from purging to atmospheric pressure. Accordingly, a predetermined air pressure level is maintained in the purge volume, so that the outlet of the turbocharger can never be communicated to atmospheric pressure.
摘要翻译：压缩空气系统包括空气压缩机，其空气压缩机的入口与车辆发动机涡轮增压器连通。空气压缩机的出口通过空气干燥器连通到储存容器。调节器响应于储存器中的压力水平，以在储存器中的压力达到预定值时产生卸载空气压缩机的卸载信号。卸载信号也通过控制阀连通，以在压缩机卸载期间吹扫空气干燥器。控制阀关闭调速器和空气干燥器之间的连通，以将空气干燥器的净化容积中的预定压力水平捕获，以防止空气干燥器吹扫到大气压力。因此，在净化容积中保持预定的空气压力水平，使得涡轮增压器的出口永远不能传递到大气压力。

摘要： Mechanism for cleaning and drying compressed gas (10) includes a housing (12) having an open end closed by an end cover (14). A desiccant canister (16) is mounted on a plate (24) which is clamped between the end cover (14) and the housing (12) so that the canister (16) is received within the housing (12). A circuitous passage (78) communicates an inlet port (76) with a sump cavity (68) which is communicated with the canister (16). Heat is transferred from the gas to the walls of the passage (78) as the gas passes therethrough. The passage (78) cants toward the sump (68) so that moisture tends to drain into the latter. A dump valve (110) periodically communicates the sump cavity (68) with atmosphere to thereby regenerate the desiccant in the canister (16) and to void the contaminants from the sump cavity (68).

摘要： A parking brake control circuit engages the parking brake of a vehicle when the transmission of the vehicle is in the “park” position and the engine of the vehicle is turned off, without requiring the constant application of electrical power. The parking brake control circuit utilizes latching solenoid technology that eliminates the need for a constant voltage source. A time-delay relay is used to change the state of the latching solenoid. The time-delay relay is preferably activated through a circuit containing an engine oil pressure switch, a transmission park switch and a vehicle speed switch. Activation of the relay latches the solenoid in a position that allows the parking brake to be applied, without requiring the application of a constant voltage to the solenoid. Accordingly, the possibility of inadvertent brake application due to electrical failure is avoided.
