Palette pumps with variable displacement with direct pressure regulator The PVE are pumps with variable displacement palettes with direct pressure regulator. Available in four quantities with maximum displacement from 6.6 to 22.2 cm3/lap and with two max calibration values ​​of the pressure regulator up to 35 bar and 70 bar (standard). The fixing flange is SAE J744 - 2 holes or 4 rectangular holes, depending on the size of the pump. Cylindrical tree with SAE J744 key, the Pompante Group is equipped with distribution discs with axial hydrostatic compensation that improve its volumetric performance and reduce the usure of the components. The adjustable load spring of the pressure compensator maintains the State Ring of the Pompante Group in an eccentric position. When the pressure pressure equals the pressure corresponding to the calibration of the spring, the State Ring is moved in order to reduce the displacement, thus adapting the scope provided to the values ​​required by the system. When the scope is required, the pump delivers oil only to compensate for any drawing, keeping the pressure constant in the circuit.
