230,335. Akt.-Ges. Brown, Boveri, et Cie. March 15, 1924, [Convention date]. Ballasting.-Air scavenging and charging blowers for ships' Diesel engines, particularly on submarines, have means to connect them to work in parallel on to the engines or in series on to the ballast tanks or the like. The means may consist of a number of separate slide valves, or as shown in Fig. 1, of four change-over flap valves c, d, e, f, and a non-return flap valve. Either of the blowers a, b may be connected to either of the engines a1, b' or they may be connected in series for blowing out the tanks through the pipe g. The movable diffusers of the blowers may be operated by the valve operating mechanism l, Fig. 4. All the connections may be controlled by a single change-over valve mechanism constructed as shown in Fig. 5.
