AUTOMATIC SYSTEM OF PRESSURE CONTROL IN PNEUMATIC SYSTEM OF TRACTIVE TRANSPORT DEVICE Russian patent published in 2011 - IPC F15B7/04 G05D16/00 

FIELD: machine building.

SUBSTANCE: automatic system of pressure control in pneumatic system of tractive vehicle consists of pneumatic system connected with compressor, and of micro-processing control element of continuous action, to outputs of which there are connected pressure gauge connected to pneumatic system of tractive vehicle via pipeline and rotation velocity sensor of compressor shaft connected to shaft of compressor. These sensors are connected to outputs by means of analogue-digital converters. Through the digital-analogue converter the output of the micro-processing control element is connected to an amplifier coupled with winding of a tractive electro-magnet of a transducer of electric signal into a pneumatic one. The input of the transducer is also connected with the pneumatic system of the tractive vehicle. The shaft of the compressor is driven to rotation from a shaft of hydro-volumetric engine by means of pipelines communicated with a hydro-volumetric pump, oil filter and oil tank. The hydro-volumetric pump, the shaft of which is driven from the shaft of a heat engine, is connected with oil coolers via a pipeline. The control element of continuous action corresponds to a membrane spring one-way action drive with an adjusting nut. A rod of the drive is connected with a distributing washer of the controlled hydraulic pump. A membrane chamber is connected with the pneumatic system of the tractive vehicle via a pipeline.

EFFECT: upgraded quality of operation of automatic system of pressure control in pneumatic system of tractive vehicle.
