توضیحات
-The VPPL are variable displacement axial-piston pumps
with variable swash plate, suitable for applications with
open circuits and intermediate pressures.
— They are available in seven nominal sizes, with
displacements of ۸, ۱۶, ۲۲, ۳۶, ۴۶, ۷۰ and 100 cm3
/rev.
— The pump flow rate is proportional to the rotation speed
and to the angle of the swash plate, which can be
continuously modulated. The maximum and minimum
angle can be limited mechanically via suitable regulating
screws.
— They are usually supplied with a SAE J744 2-hole flange
and a SAE J744 cylindrical with key shaft.
— They are available with four different types of regulating
control, each according to the application needs.
