Claim:
1. A braking system including: a dynamic brake, including a hydraulic ram, containing a cylinder, a piston movable within the cylinder, and a chamber capable of being filled to displace the piston within the cylinder and actuate the brake, a brake feed circuit, including a reservoir, a pump and a line for feeding the brake, a brake control device, including a fluid pressure regulating valve of the pressure within the brake chamber, and a progressive control, said device being designed to deliver a predetermined pressure into the chamber depending on the degree of actuation of the control, wherein the fluid pressure regulating valve includes an inlet/outlet port connected to the feed line, an inlet/outlet port connected to the reservoir and an inlet/outlet port connected to the brake chamber, the fluid pressure regulating valve being designed to selectively connect the inlet/outlet port connected to the chamber to one or the other of the other ports depending on the pressure in the chamber and on the degree of actuation of the control, and wherein the braking system further includes a cooling line of the chamber, designed to renew the fluid contained in the chamber to provide cooling for said chamber.
