Working - fluid supply. - In systems such as are employed, for example, on ships, in which exhaust steam from auxiliary engines and steam generated in an evaporator are utilized conjointly for supplying steam to lowpressure turbines the steam generated in the evaporator is controlled in accordance with the steam pressure in the system, so as to compensate for any surplus or deficiency in the supply from the auxiliary engines, and thus furnish an approximatly constant joint supply. As shown in Fig. 1, the cock l which regulates the admission of steam to the heating-coils of an evaporator is controlled by a diaphragm s subject to the steam pressure in a reservoir r, into which the joint supply is delivered. In a modification, the diaphragm controls the discharge of drainage water from the heating-coils.
