PNEUMATIC SHOCK ABSORBER Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: device eliminates leak of compressed air to the atmosphere from the pneumatic shock absorber at release due to fast filling of pneumatic bottle 14 with compressed air escaping from pneumatic shock absorber and increases and decreases clearance between the body of transport facility and road as compared with average level; to this end, shut-off valve 20 shell be open. Compressed air fed through valves 5 fills pneumatic shock absorbers, thus increasing the clearance between the body of transport facility and road to maximum. When shut-off valves 20 and 21 closed and shutoff valve 23 is open, compressed air escapes to the atmosphere through pipe line 22. Clearance between the body of transport facility and road becomes minimum by gravity. EFFECT: enhanced efficiency. 1 dwg
