Abstract

PURPOSE:A fluidic pressure buffer to alleviate the impacts at the stopping time of a moving material in such a way that a gap is provided between a cylinder and a piston with the exception of the propinquity to the final stroke of the piston, and its velocity is decelerated at the time short of terminating the piston action.
