Abstract
High and low pressure pump for hydraulic actuators, characterized in that it consists of a body in which two impellers are mounted that work subordinated and simultaneously, being, of these two devices, one of low pressure formed by a gear pump and its regulation mechanisms and the other, high pressure, constituted by a piston pump, its regulation and drive mechanisms, determined the first device sending fluid, at low and adjustable constant pressure, to a receptacle from where it is collected. second device and raise its pressure to the high preset pressure in the regulation mechanisms.
