HYDRO PNEUMATIC DAMPER

摘要

FIELD: machine building.SUBSTANCE: proposed damper comprises case 1 connected with entity to be damped. Main rod 2 is attached to base by appropriate attachment assembly 3. Cylinder 5 arranged inside main rod 2 to make along with its wall an annular gas cavity 6 communicated via holes 8 with gas cavity of case 1. Cylinder 5 houses extra rod 4 with hollow rod 10 with piston 11 secured thereto. On one side rod 12 with piston 13 is located in hollow rod 10 while, on opposite side, it has its end coupled with case 1. Main rod 2 houses dividing piston 15 fitted on hollow rod 10 to seal hydraulic cavities 15 and 16 relative to case gas cavities 9.EFFECT: decreased dimensions, higher capacity, reduced dynamic load transmitted to damped entity.2 cl, 3 dwg
