The invention belongs to the technical field of hydraulic actuating cylinders, and particularly relates to a single-nozzle type undercarriage emergency release actuating cylinder which comprises a nozzle, a piston, a reset spring, a piston rod and an outer cylinder. The piston is connected with one end of the piston rod, the piston rod is sleeved with an outer cylinder opening, the piston is sleeved with an outer cylinder, the outer cylinder is divided into a rod cavity and a rodless cavity, the reset spring is installed in the rod cavity and provides pretightening force for the piston to move towards the rodless cavity, and the pipe nozzle is used for providing hydraulic oil for the actuator cylinder or discharging the hydraulic oil. The actuating cylinder adopts a single pipe nozzle and a cavity is additionally provided with a reset spring, the functions are not reduced when the actuating cylinder adopts double pipe nozzles, but the arrangement of one pipeline can be reduced by adopting the single pipe nozzle, the use space during pipeline arrangement is reduced, the weight of the arranged pipeline is reduced, and the whole cost is also reduced.

    本申请属于液压作动筒技术领域,特别涉及一种单管嘴式起落架应急放作动筒,包括:管嘴、活塞、复位弹簧、活塞杆、外筒;与活塞杆一端连接活塞,外筒口套在活塞杆上,活塞套在外筒中,将外筒分成有杆腔与无杆腔,复位弹簧安装在有杆腔中,向活塞提供向无杆腔运动的预紧力,一个管嘴,用于向作动筒提供液压油或者排出液压油。作动筒采用单管嘴、腔体增加复位弹簧的形式,和作动筒采用双管嘴的时候的功能并未减少,但采用单管嘴形式可减少一条管路的布置,减少了管路布置时的使用空间,并减轻了布置管路的重量,也降低了整个成本。
