Abstract
The tubular part (9) of the hub (7) of the piston assembly (5), which encloses the distribution valve (8), supports an assembly (200) consisting of a guiding ring (21) and a seal (20) cooperating with the internal wall of a tubular part (22) mounted, for example crimped, inside a central duct (23) of the rear shell (2) of the servomotor housing (1) and having a first end part (26) extending so as to project axially into the rear working chamber (4) of the servomotor. Advantageously, the tubular part (22) has a second end part (37) forming a stop (36) for a limit member (31) associated with input rod (12) and forming a bearing for the return spring (30) of the input rod (12).
