Document Type and Number:
WIPO Patent Application WO/2022/102835
Kind Code:
A1
Abstract:
In a directional control hydraulic valve and a hydraulic system including same according to the present invention, the directional control hydraulic valve comprises: a first valve configured to control a flow of a fluid flowing in from a first input port in conjunction with a solenoid valve that is switched to excitation (on) or non-excitation (off); and a second valve connected to the first valve and configured to control a flow of the fluid flowing in from the first valve by the fluid flowing in from a second input port or a third input port, wherein at least a portion of the fluid passing through the first valve is discharged to a first output port, and is introduced into the second input port or the third input port. In addition, it is characterized in that multiplexing of a hydraulic system is implemented by configuring a hydraulic system including two or more directional control valves.
