JACK SYSTEM WITH AUTOMATIC LOCKING OF THE PISTON IN HIGH POSITION, ESPECIALLY FOR AIRCRAFT
Abstract:
This invention provides a jack system (2) provided with a cylinder (14) provided with stop means (32). It also comprises:a body (36) hinged about an end (18) of the piston, the body comprising stop means (54) and being able to occupy a first angular position authorising the extraction of the piston, as well as a second angular position uniquely allowed when the piston occupies a position such that the means (54) are located beyond the means (32) in an extraction position (34), the body occupying the second position providing the facing of means (32, 54); andan electromagnetic attraction/repulsion device (64) designed to provide the displacement of the body (36) from the first position to the second position, and inversely.
Abstract(Chinese):

本发明提供了一种具有设置有停止装置（32）的气缸（14）的千斤顶系统（2）。 它还包括：围绕活塞的端部（18）铰接的主体（36），该主体包括止动装置（54），并且能够占据授权提取活塞的第一角度位置以及第二角度 当所述活塞占据位置使得所述装置（54）位于提取位置（34）内超过所述装置（32）的位置时，唯一允许的位置，所述主体占据提供装置（32,54）的面的第二位置。 以及被设计成提供主体（36）从第一位置到第二位置的位移的电磁吸引/排斥装置（64），并且相反地。
