AUTOMATIC PRESSURE CONTROL SYSTEM FOR TRACTION VEHICLE PNEUMATIC SYSTEM Russian patent published in 2005 - IPC

FIELD: mechanical engineering; traction vehicles.

SUBSTANCE: invention relates to piston compressor plants of traction vehicles. In proposed automatic pressure control system containing pneumatic system connected with compressor driven by shaft of heat engine through reduction gear and variable-filling fluid coupling whose inputs is connected with control oil feed spool delivering oil into fluid coupling, on-board microprocessor controller is used to inputs of which pressure pickup connected by pipeline with pneumatic system of traction vehicle and compressor shaft speed pickup connected with compressor shaft are connected though analog-to-digital converters. Output of on-board microprocessor controller is connected through digital-to-analog converter with amplifier connected to electric signal-into-pneumatic signal converter whose input is also connected with pneumatic system of traction vehicle and outer put is connected with input of diaphragm spring single-acting drive of spool which controls delivery of oil into fluid coupling.

EFFECT: improved reliability of compressors, reduced consumption of oil.
