Hydraulic Apparatus Based on Confluence Control Mode
A hydraulic apparatus based on a confluence control mode includes a load sensing unit provided with first and second reversing valves, and a throttle governing unit provided with a fourth reversing valve. A confluence valve and a one-way valve, which communicate with the load sensing unit and the throttle governing unit, are arranged on a parallel oil path arranged in parallel with the fourth reversing valve. The confluence valve includes a confluence channel that controls opening and closing of the parallel oil path to shunt fluid of the throttle governing unit to the load sensing unit. A first pilot pressure acting on the first reversing valve and a second pilot pressure acting on the second reversing valve act on the confluence valve independently or simultaneously to change a position of the confluence channel, thus implementing reversing of the confluence valve.
