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

Abstract RU 2258015 C2

FIELD: transport engineering.

SUBSTANCE: invention is designed for improvement of piston compressor plants of traction vehicles, for instance, diesel-driven rolling stock in which compressors are driven by heat engine. Proposed automatic pressure control system contains pneumatic system connected with compressor driven by shaft of heat engine through mechanical reduction gear and variable filling fluid coupling. Input of coupling is connected with spool which control delivery of oil into fluid coupling. System is furnished with continuous action control member whose control spool is coupled with diaphragm spring one-way drive connected by pipeline with pneumatic system of traction vehicle.

EFFECT: provision of automatic maintenance of pressure in pneumatic system of traction vehicle irrespective of flow rate, temperature and pressure of automatic air.
