METHOD OF SELF-CONTAINED POWER SUPPLY OF DRIVE DEVICES OF CONSTRUCTION AND LIKE MACHINES Russian patent published in 2004 - IPC

FIELD: public services, timber industry, agriculture. SUBSTANCE: invention relates to drives of mobile construction and like machines, such as those used in public services, timber industry and agriculture. Invention provides separate or combined starting of all motors, including internal combustion engine, which is used to drive machine running gear, leaving all other functions to other motors of said multimotor pneumogas drive. Proposed system includes internal combustion engine and motors of working members with common supply from bottled compressed gas system with delivery of high-pressure gas into working member motors. Gas at low pressure passes from working members either into used gas receiver with subsequent restoration to high-pressure state by passing the gas through multistage heat compressor, of for preparation of gas-motor fuel for internal combustion engine. EFFECT: possibility of separate or combined starting of all motors and internal combustion engine. 2 cl, 1 tbl, 1 dwg
