Abstract

An oleopneumatic jack device of step structure with fast and then slow advance, characterized in that it comprises, on the one hand, a control cylinder in which a main piston integral with a hollow rod and a float mounted sliding along a piston move. This hollow rod, and, on the other hand, a drive cylinder containing a motor piston carrying the thrust member, the volume comprised between the float and the motor piston of a liquid being filled and separated into two chambers by a diaphragm that it is sealed by the hollow stem of the main piston at the time of the slow advance, a pneumatic distributor being furthermore provided to send at will a motor fluid under pressure between the main piston and the float for rapid advancement and between the main piston and the piston. Bottom of the control cylinder with a view to the slow advance, also allowing an antagonistic means the return of the mobile organs to position starting ion.
