Abstract
A transmission includes a set of pulleys, in which at least one disc is axially displaceable and provided with cylinder piston elements. The cylinder/piston elements include at least one pressure chamber with radial walls and concentric cylinder walls and at least one of the radial walls of the pressure chamber is secured to one of the concentric cylinder walls by an immovable fit. The wall near to the fit is produced with a resiliently hingeable feature, in which the hinging feature is realized with the inclusion of an axially extending sleeve like foot part, integral to the wall, and with both axial faces thereof extending uninterrupted smoothly up to the lower end part of the wall.
