Abstract

Hydraulic differential racing jack of the type comprising a body forming a cylinder containing a sliding piston delimiting two opposite variable volume capacities and which is associated with a piston rod passing through one of the bottoms of the cylinder whose other bottom extends internally by a hollow and fixed stem that permanently penetrates in a blind bore offered by the piston-rod assembly, said rod opening both externally to the cylinder and in the blind bore, characterized in that the cylinder has a first bore with a section greater than that of the piston, which extends over most of its length and joined to a second section bore corresponding to the piston and limited in the vicinity of the prolonged bottom by the fixed hollow shank and because, in combination, said hollow and fixed shank has a section superior to that of a part of the piston rod that extends the part that ue delimits the blind bore and traverses the corresponding bottom of the cylinder.
