Abstract:
An electric-control multimode steering valve comprises: a flow distributing and collecting valve, a first electromagnetic valve, and a second electromagnetic valve. A valve body comprises four groups of paired valve oil ports. First oil ports of the first and second electromagnetic valves are in communication with a first group. Second oil ports of the first and second electromagnetic valves are in communication with a second group. A third oil port of the first electromagnetic valve is in communication with a flow collecting port of the flow distributing and collecting valve. A first flow distributing port of the flow distributing and collecting valve and a third oil port of the second electromagnetic valve are in communication with a third group. A second flow distributing port of the flow distributing and collecting valve and the third oil port of the second electromagnetic valve are in communication with a fourth group.
