Abstract
A hydraulic capacity having a hollow body (2) made of a rubber material and a rigid body (3) which surrounds the hollow body (2) to limit the expansion of the hollow body (2). The hydraulic capacity containing at each instant an instantaneous volume (V) of fluid to which an instantaneous pressure is applied as a function of the instantaneous volume (V). The hollow body (2) has a wall (21) which is simultaneously in contact with the casing (3) and at least via of a first zone (Z1) and a second zone (Z2). The first zone (Z1) has a first thickness (E1) and the second zone (Z2) has a second thickness (E2) which are separated from each other by a third zone (Z3) having a third thickness (E3). The third zone (Z3) being separated from the casing (3) and the third thickness (E3) being different than the first (E1) and second (E2) thickness such that an instantaneous pressure (P) of the fluid is controlled according to a predefined relationship.
