Pressurizing oil tank for electro-hydraulic integrated actuator

The pressurizing oil tank comprises an oil tank barrel, an elastic body and a rear end cover, the two ends of the oil tank barrel are fixedly connected with a valve body of a control valve set and the rear end cover respectively, the elastic body is arranged in the oil tank barrel, and the oil tank barrel is filled with hydraulic oil according to the capacity of the oil tank. The elastic body keeps a certain compression amount in an initial state, and hydraulic oil in the oil tank is kept in a positive pressure state. According to the utility model, the elastic body is adopted to meet the rapid oil supplementing requirement of the electro-hydraulic integrated actuator, and the advantages of rapid response and high reliability are achieved. 本实用新型涉及一种用于电液集成作动器的充压油箱，包括油箱筒、弹性体、后端盖，所述油箱筒两端分别与控制阀组的阀体和后端盖固定连接，所述弹性体置于油箱筒内部，油箱筒内部根据油箱容量充有液压油，使得弹性体在初始状态下保持一定的压缩量，油箱内部液压油维持在正压状态。本实用新型采用弹性体满足电液集成作动器的快速补油需求，具有响应快、可靠性高的优点。
