Abstract

A device for governing the power of a pump has a conventional system for varying its cylinder capacity and a control arrangement therefor including linked members indicative of the pump delivery rate and the pump output pressure and regulator operable by said linked members to deliver the output of an auxiliary pump to one or the other chamber of a double acting ram of the control system if the linked members indicate that an increase or decrease in power is necessary or to a reservoir if the linked members indicate that the power is correct.
