Abstract
Hydraulic bushings (1) are generally provided with a peripheral flange in which a pressurizing means (3, 4, 5) is arranged. A desire has been expressed to eliminate the peripheral flange. According to the present invention this is made possible by placing the pressurizing means (3, 4, 5) in the rear end (6) of the bushing (1).
