PNEUMATIC DAMPING SLAVE MECHANISM Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to simplest double-acting non- damping devices and devices designed for connection of different suspensions of vehicles with chassis playing the part of pneumatic suspensions, shock absorbers and suspension lifts. Proposed mechanism contains two coaxial rubber-cord bags, intermediate member hermetically connected with opposite end faces of rubber-cord bags and inter communicating their spaces through valve-andthrottle device and with external adjustable source of pressure P₁, and rod hermetically connected with opposite end faces of rubber-cord bags by means of pistons. Rod can travel along device axis in sliding bearings, one of which interacts with piston, and the other with surface of rod and is arranged between rubber-cord bags. One rubber-cord bag is placed inside hermetically sealed housing whose space is connected to external adjustable source of pressure P₂, not exceeding pressure P₁ inside rubber-cord bag. EFFECT: improved reliability. 3 cl, 4 dwg
