Valve-controlled hydraulic machine has high-pressure valve arrangement that is actively switched and associated cylinder-piston units that are operable in fragmentary mode in which valve arrangement is closed during total stroke

摘要

#CMT# #/CMT# The valve-controlled hydraulic machine has cylinder-piston units (4,6) of each provided with a low-pressure valve arrangement (22) provided at a low pressure side and a high-pressure valve arrangement (16) provided at a high pressure side. High-pressure valve arrangement is actively switched and the associated cylinder-piston units are operable in a fragmentary mode in which the valve arrangement is closed during a total stroke from a first dead center to a second dead center and after or before passing through the second dead center. #CMT#USE : #/CMT# Valve-controlled hydraulic machine. #CMT#ADVANTAGE : #/CMT# The generation of noise is reduced during partial load operation of the valve-controlled hydraulic machine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating the structure of valve-controlled hydraulic machine. 1 : Axial piston pump 2 : Cylinder drum 4,6 : Cylinder-piston units 16 : High-pressure valve arrangement 22 : Low-pressure valve arrangement.
