Oil path structure of embedded multifunctional two-way holding valve

The invention discloses an embedded multifunctional two-way holding valve oil way structure, and belongs to the technical field of hydraulic valves. A main valve rod is installed in the first valve element hole of the valve body in a matched mode. A left one-way valve element, a linkage valve rod and a right one-way valve element are sequentially installed in a second valve element hole of the valve body. The oil port P and the oil port T are communicated to the main valve rod; the oil port A is communicated with a left one-way valve core and a spring cavity thereof; the oil port B is communicated with a right one-way valve core and a spring cavity thereof; the oil port Pi and the oil port DR are communicated through a linkage valve rod; the other end of the oil duct I is communicated with the right end of the left one-way valve core and the left end of the linkage valve rod; and the other end of the oil duct II is communicated with the left end of the right one-way valve core and the right end of the linkage
