Abstract
An automatic-locking hydraulic jack has a piston (1, 30) that slides into a cylinder (3-2, 32). Locking of the piston is achieved by elastic deformation of either the inside wall (2) of the cylinder or of the outside wall of the piston (30) so as to ensure that the one is tightly clamped over the other. The locking of the jack is maintained by pressure that causes the elastic deformation of the inside wall of the cylinder (3-2) or of the outside wall of the piston (30), until the jack is unlocked by neutralizing the elastic deformation.
