Design principles

A hydraulic buffer consists of a piston, a piston rod and a cylinder pipe. The principle of a buffer is to allow free movements during normal operations and a temporarily rigid connection during a shock loading from an earthquake, traffic breaking, or a heavy wind blow, for instance. The resulting reaction force depends on the flow of a fluid that passes from one chamber into the other of the cylinder pipe. The fluid, a special silicon oil, is squeezed through small holes in the piston (for smaller buffers the fluid flows through the gap between the pipe and the piston). The size of the holes determines the damping characteristics of the buffer. The mageba hydraulic buffer allows bridge engineers to strengthen almost every bridge at a lesser cost compared to conventional strengthening methods.
