Beschreibung
Zusammenfassung:	FIELD: transport engineering; vibration isolating devices. ^ SUBSTANCE: operator's seat pneumatic suspension has seat skeleton with cushion and backrest, guide arrangement made in form of parallel horizontal levers, and shock absorbing device consisting of operating chamber and damping chamber. Suspension is furnished with level regulator made in form of valve with floating piston enclosing the rod and pressed by spring to projections of regulator housing for overlapping channels communicating with pneumatic main line to level pressure in said chambers. Interchamber throttle is made in form of mass elastically secured by means of diaphragm permeable for air with clearance over throttle hole made in partition separating operating and damping chambers. Spring-loaded ball can be secured on end of rod, and elastomer can be used as spring pressing the piston. ^ EFFECT: improved vibration isolation by stabilizing vibrations of object. ^ 2 cl, 2 dwg
