Abstract

A device for limiting the delivery output of a jack having a complementary chamber of substantially smaller diameter opening into the end of a main delivery chamber, the complementary chamber having a delivery conduit, a deformable member coupled in translation with a piston rod and being capable of abutting the piston, the deformable member being capable of penetrating into the complementary chamber from the main delivery chamber and being of slightly smaller diameter and having complementary walls with respect to the walls of the complementary chamber to form a passage between the end of main delivery chamber and the complementary chamber, the deformable member being deformed by fluid pressure to increase the transverse section of the passage between the walls of the deformable member and the complementary chamber.
