The invention relates to vibration-insulating devices, in particular, to a vibration-insulating system for cabin tamping and straightening cabs.

The purpose of the invention is to increase the efficiency of the vibration insulation properties of the cabin, reduce the weight, size and simplify the design.

The plate 4 is made hollow and is divided by partitions 5 and 6 into three tanks that are additional to the pneumatic elements 7. Cab 1 and plate 4 form the sprung cabin part, and frame 2 and hood 3 are the unsprung part of the system. Each re-20 (middle) position, the zervuar is connected to at least two pneumatic elements through a throttle capillary channel with a ratio of length to diameter equal to or greater than ten (not shown). The high regulation 25 valve 8 is rigidly connected to the carrier plate 4 of the cab and the pneumatic conduit with pneumatic elements 7. The high regulating valve 8 consists of the housing 9 with the fitting 10 supplying the compressed air 16, floating 16, which through the ball 17 lifts the floating piston 11, overcoming the resistance of the spring 12. Part air is then vented to the atmosphere, resulting in the cabin occupying the former zero
