The retention valve 4 lets flow as much hydraulic fluid is necessary for the rod return and does this at constant speed thanks to the compensatory fluid regulator 8 . The electromagnetic sensor makes sure that the mobile part performs the full extent of the return stroke. Unless this condition is fulfilled, it denies permission to move on to the next stage. The excess amount of fluid pumped with respect to the quantity required by the system for the return stroke is made to flow directly into the command unit. 3. Phase 4
