41. The vented gas drove a piston which in turn actuated the breech block. 42. The door mechanism may be actuated by Dodge Charger. 43. The Mk . III introduced hydraulically actuated doors which greatly improved bombing accuracy. 44. A later method developed for D5 systems are controlled via hydraulically actuated nozzle. 45. These actuated the overhead steel intake and exhaust valves. 46. The valves are actuated by hydraulically adjusted rocker arms with roller cam followers. 47. The piston carriage substituted and the train thence became actuated by atmospheric pressure. 48. It is spin-actuated at about 50 meters. 49. The tank was steered by conventional tillers hydraulically actuating onto external brake discs. 50. Later installations had the final nozzle mechanically actuated separately from the AB nozzle.
