Abstract
First certificate of addition for improvement introduced in the object of the main patent no. 200,541 by brake fluid with pressure undercarriage characterized in that it comprises a general conduit a reservoir of controls a source of fluid under pressure a device provided with movable stops submitted on two opposite sides to the pressures of the control tank and the general duct and can be operated by the pressure of said tank in response to a pressure reduction in the general duct to supply fluid under pressure and to make a tightening of the brakes and means actuated by the fluid under preceding pressure from said source when the movement of the device with movable stops occurs to open a supply communication in fluid under pressure between said source and said reservoir.
