Abstract: A hydraulic circuit with a compensation and energy recovery function includes a distribution module having at least one spool defining a main delivery branch and a discharge branch. The hydraulic circuit also includes a supply unit and a three-way compensated adjustment device connected to the spool discharge branch and connected to discharge at a second channel. The three-way compensated adjustment device further includes a first piloting line and a second piloting line configured so that a Maximum Load Sensing piloting signal acts on a first side and a Local Load Sensing piloting signal acts on the second side. An energy recovery device and a selection section are configured to receive a signal at reduced pressure and send it to the first piloting line to activate the three-way compensated adjustment device switching to a position where the fluid coming from the discharge branch is sent to the energy recovery device.

Abstract: A hydraulic distributor includes at least one main spool configured to define a delivery branch, and a discharge branch, a feed branch and a pressure compensator configured such that a local pressure acts on a first side thereof and a maximum Load Sensing pressure acts on a second side characterizing either the working pressure of the hydraulic section, in the case in which there is only one hydraulic section, or, in the case in which there is a plurality of hydraulic sections, each one defining a respective characteristic pressure, of the maximum pressure among the characteristic pressures of the hydraulic sections. The pressure compensator is arranged such as to respectively intercept said delivery branch and said discharge branch.
