VIBRATION-ISOLATING SUSPENSION INTENDED FOR OPERATION AT ANY ANGLE TO HORIZON Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: vibration-isolating suspension has bedframe, two brackets, at least two parallel pneumatic shock absorbers in form of main flexible shells, radial vibration dampers with guides and columns placed inside guides. Columns are made fast by ends in brackets and are embraced by main flexible shells. Device has two additional flexible shells installed coaxially with main shells and arranged at opposite side of equipment flange in the same manner as main shells. System to deliver compressed air into flexible shells through channels made in columns is provided. Gas is delivered through channels in main columns of main shells through check valves. Each guide and column can be divided into two parts. Suspension has control unit and pressure transmitter installed between last partitions forming together with corresponding flexible shells, higher pressure insulated chambers. Compressed air delivery system has special devices to regulate pressure in higher pressure chambers. More over, suspension can be furnished with position transmitters connected with control unit. EFFECT: enhanced vibration protection. 3 cl, 2 dwg
