HYDRAULIC SYSTEM FOR HYDRO-MECHANICAL MACHINES COMPRISING ROTARY MECHANISM AND BOOM CYLINDER

摘要

This disclosure relates to a hydraulic system for a hydro-mechanical machine comprising a rotary mechanism 102 and a boom cylinder 158. The hydraulic system includes a primary accumulator 114 configured to receive and store high-pressure fluid in response to starting and stopping of the rotary mechanism 102. A control system 126 configured to enable passage of the high-pressure fluid stored in the primary accumulator 114 to a rotary control valve 108 configured to control the rotary mechanism 102, and a boom control valve 154 configured to control the boom cylinder 158 through the hydraulic supply circuit 100, based on a predefined pressure threshold associated with the primary accumulator 114. A secondary accumulator 138 coupled to the primary accumulator 114 and the control system 126 via the hydraulic supply circuit 100 is configured to store surplus high-pressure fluid provided by the primary accumulator 114 through the hydraulic supply circuit 100.
