The pressure cartridge (1) includes a housing (2) with a stepped boring (5), containing a primary piston (30) and a secondary piston (4), with a chamber (22) between them filled with hydraulic oil, bounded by the piston endfaces (6, 7). A spring (9), acting on the secondary piston, loads it towards the primary piston.
