The monostable prefill valve comprises a valve body, a monostable diverter valve and a prefill valve body, the monostable diverter valve and the prefill valve body are arranged in the valve body, the valve body is provided with an oil inlet and a prefill opening, a prefill oil way communicated with the oil inlet and the prefill opening is arranged in the valve body, and the monostable diverter valve can control the flow of oil passing through the prefill oil way. The prefill valve can control the opening degree of the prefill port, a first valve cavity is further formed in the valve body, the first valve cavity is provided with an inlet and a first outlet, a branch communicated with the prefill oil way and the inlet is further arranged in the valve body, the prefill valve comprises a first reversing valve arranged in the first valve cavity, and the first reversing valve can control the opening degree of the inlet and the opening degree of the first outlet; a first feedback oil way and a second feedback oil way are arranged between the first outlet and the two axial ends of the first valve cavity correspondingly, and the first feedback oil way and the second feedback oil way can feed back pressure of the first outlet to the two ends of the first reversing valve. According to the monostable prefill valve, the functions of flow dividing and liquid filling can be achieved at the same time, and the stability during liquid filling can be improved.

    本发明涉及一种单稳充液阀,单稳充液阀包括阀体及设置于阀体内的单稳分流阀和充液阀,阀体具有进油口及充液口,阀体内设有连通进油口和充液口的充液油路,单稳分流阀能够控制通过充液油路的油液流量,充液阀能够控制充液口的开度,其中:阀体内还设有第一阀腔,第一阀腔具有进口及第一出口,阀体内还设有连通充液油路及进口的支路,充液阀包括设置于第一阀腔内的第一换向阀,第一换向阀能够控制进口及第一出口的开度;第一出口与第一阀腔轴向两端之间分别设有第一反馈油路及第二反馈油路,第一反馈油路及第二反馈油路能够将第一出口的压力反馈至第一换向阀的两端。该单稳充液阀能够同时实现分流与充液的功能,并且还能够提高充液时的稳定性。
