Pump; Axual-piston-piston-piston-piston-type engines of type MG112/32M with a pressure regulator are used in volumetric hydraulic drives of machines and assemblies in the controlled pump or hydraulic motor modes.
The pump is intended to convert the mechanical energy of rotation of the drive shaft into the variable energy in terms of working fluid flow (in a closed scheme).
For the drive of executive mechanisms requiring the unacceptable regulation of the rotation frequency when maintaining constant pressure in the hydraulic system.
Working volume-from minimum.
