This has now been completed, and if you are not satisfied with the A.C. then this has one or two advantages - i.e. - (1) the diaphragm must work through its proper range or not at all, and the stroke must be in the proper place (important RR. point.) (2) all the parts are circular. It suits our P. 2. (L. and R.H.) and can be adapted for the 25HP. (J.1.) It sweeps away quite a lot of autovac work and cost, therefore is wanted without delay, as well as being absolutely necessary for the double carburetters. R.{Sir Henry Royce} | ||
