The invention relates to an aircraft hydraulic system centralized refueling device and an aircraft. The centralized refueling device comprises a manual pump assembly, an oil filter, a refueling selection valve and a connecting plate, wherein the manual pump assembly, the oil filter and the refueling selector valve are sequentially mounted on the connecting plate, and an internal oil way is arranged on the connecting plate; the manual pump assembly comprises a manual pump, an oil suction pipe and an operating handle, and oil can be pumped into the manual pump from the oil suction pipe through reciprocating operation of the operating handle and then pumped into an internal oil way on the connecting plate; the oil filter is used for ensuring the cleanliness of filled oil; the input end of the refueling selector valve is connected to an internal oil way located on the connecting plate and located on the downstream of the oil filter, and the refueling selector valve is provided with a first output position, a second output position and a third output position which are connected to the first hydraulic system oil tank, the second hydraulic system oil tank and the third hydraulic system oil tank respectively. According to the technical scheme, the centralized refueling device has the following beneficial technical effects that compared with a tubular installation structure, the centralized refueling device is more compact, fewer in potential leakage points and more convenient to install, maintain and use.

    本发明涉及飞机液压系统集中加油装置及飞机。该集中加油装置包括手动泵总成、滤油器、加油选择阀、连接板;其中,手动泵总成、滤油器、加油选择阀依次安装在连接板上,连接板上设有内部油路;手动泵总成包括手动泵、吸油管、操作手柄,操作手柄的往复操作能将油液从吸油管泵入手动泵,进而泵入连接板上的内部油路;滤油器用于确保加注油液的清洁度;加油选择阀的输入端连接至位于滤油器下游的、连接板上的内部油路,加油选择阀具有第一、第二和第三输出位置,分别连接至第一、第二和第三液压系统油箱。根据上述技术方案,本发明能起到以下有益技术效果:与管式安装构型相比,该集中加油装置更紧凑,潜在泄漏点更少,安装、维护、使用更便捷。
