Beschreibung
Zusammenfassung:	The utility model relates to the technical field of hydraulic pressure, in particular to a load maintaining sheet type multi-way valve which comprises a valve body, a valve element hole, a working oil cavity, an oil inlet cavity and an oil return cavity are arranged in the valve body, the working oil cavity, the oil inlet cavity and the oil return cavity are communicated with the valve element hole, the oil inlet cavity is connected with an oil inlet, and the oil return cavity is connected with an oil return opening. The valve element is arranged in the valve element hole and used for oil way conversion. The one-way valve hole is communicated with one working oil cavity, a one-way valve is arranged in the one-way valve hole, and a cavity communicated with the working oil cavity is formed in the one-way valve; the middle body is provided with a pilot channel and a middle channel, the pilot channel is used for communicating the pilot oil cavity with the valve element hole to push the valve element to move, the
