Hydraulic aircraft/stores cartridge

摘要

A hydraulic cartridge suitable for releasing stores in aircraft relies on a pressurized piston rod which extends upon release of hydraulic pressure. The piston rod is enclosed in a cylinder and connected to a source of hydraulic fluid. Upon arming of the piston rod a hydraulic liquid is pumped into the piston rod and forces out a gas via an accumulation piston. Upon complete filling of the piston rod, a trigger is held in place by the pressurized fluid. Upon release of pressure, the pressure on the trigger becomes unbalanced and a spring releases the trigger from the piston rod permitting it to extend.
