The use of four distinctvalves governed by a single reversing gear permit the de-signer to choose in the largest measure, among the meansabove indicated, those that appear to him most advan-tageous to regulate the compiession phases. But when in thisregulation the considerable influence of the speed is considered,whose effect may be equivalent to an increase of the initialvolume U of the compressed steam, it is indispensable, inorder to prevent the finill pressure p from attaining in certaincases an excessive value, to be able to increase the value of cor the fall of pressure in the receiver. In other words, this result cannot be obtained in practiceunless we reserve for ourselves the mean
