| 摘要 | A locking mechanism for a brake cylinder that has a tube surrounding the hollow shaft of the brake cylinder with a first set of teeth formed along an outer surface thereof. A gate having a second set of teeth corresponding to the first set of teeth is moveable in between a first position, wherein the first and second set of teeth are engaged to prevent movement of the brake cylinder piston, and a second position where the first and second set of teeth are disengaged to allow movement of the brake cylinder piston. A spring biases the gate into the locked position and a supplemental piston responsive to a source of brake pipe pressure can move the gate into the unlocked position so that the main piston is free to move. | ||||||
