Abstract
The spline-ended connecting shaft of an engine-accessory disconnect device has a radially outwardly projecting drive flange coaxially secured to an intermediate portion thereof. A housing captively retains the flange, permitting axial translation and rotation of the flange and shaft relative to the housing. A burst of compressed air injected into the housing is caused to exert sequentially opposite forces on the flange to rapidly initiate and terminate axial uncoupling motion of the shaft without imposing appreciable rigid impact force on the disconnect components. The shaft extends through openings in end walls of the housing so that it is freely rotatable and axially translatable relative to the housing without touching the surfaces of the housing openings.
