    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.

    Abstract translation: “具有气动执行的液压压力发生单元”特别是由低压空气激活的多功能单元,其由气动自动化的至少一个泵(1),优选两个泵(1和2)组成,包括气动缸 除了两个对称和相对的液压柱塞(8和9)之外,还具有限制上液压室(1A和2A)以及另一下液压室(1B和2B)的中间柱塞(7) 体积,其中由于它们并联并且异相工作,因此需要减少的油量并且消除其脉动运动。
