Abstract

459,139. Torpedoes. MACKENZIE, W. B., Admiralty, London, and CROKER, T. J., H.M.S. Vernon, Portsmouth. July 1, 1935, No. 18706. [Class 9 (ii)] Relates to arrangements of valves for blowing out ballast from practise heads of torpedoes, of the kind in which a device subjected to the air pressure in the air flask causes a valve to open to perform the blowing out when the pressure in the flask falls below a given value. According to the invention, this valve is made to act as a non-return valve or is combined with a non- return valve which is put out of action when the apparatus is assembled ready for use. As shown in Fig. 1, a spring-loaded non-return valve 6 is arranged in line with a spring-loaded plunger 16 at the front end of the air flask 2 and the rear end of the practise head 4. The plunger is pulled outwards while the flask is being charged, and is afterwards released and bears against the stem of the valve 6 but with insufficient pressure to open that valve until the pressure in the flask has fallen to a given value at the end of the practise run. The valve then opens and the practise head is blown empty by the air from the flask. In the modification, Fig. 2, a spring- loaded non-return valve 24 is put out of action when a spigot 23 is secured by a nut 22 to assemble the blowing valve device which contains a valve 26 subjected to the pressure of a spring 36 through a plunger 34. The valve 26 is held closed by a screw-down spindle 27 when the air flask is being charged. After this, the spindle 27 is unscrewed and the air pressure holds the valve 26 closed until this pressure falls at the end of the practise run, whereupon the spring 36 opens the valve and the ballast is blown out. The plunger 34 ends in a piston 38, which can be operated by fluid pressure from a pipe 37 to open the valve 26 independently of the pressure in the air flask. For example, a small explosive charge may be fired after a given run of the torpedo and the explosive gases led to the piston 38 by the pipe 37.
