Abstract: A “HYDRAULIC PRESSURE GENERATION UNIT WITH PNEUMATIC ACTUATION” in particular a multifunction unit activated by low pressure air, consisting of at least one pump (1), preferably two pumps (1 and 2), which are pneumatically automated, comprising a pneumatic cylinder (5) with a medial plunger (7), in addition to two symmetrical and opposite hydraulic plungers (8 and 9) limiting an upper hydraulic chamber (1 A and 2 A) and another lower hydraulic chamber (1 B and 2 B) having different volumes, wherein since they work in parallel and out-of-phase a reduced oil volume is required and the pulsating movement thereof is removed.
