The piston isshown in the position it would occupy soon after compression munication through the passage c, with the exhaust cavity Lin the valve and the exhaust pipe N, it is evident that the steamwhich is compressed iu //can thus escape to the exhaust pipe,and that I lie back pressure will thus be relieved in front of thepiston. Of course an exactly similar action takes place at theother end of the cylinder when the piston moves in the oppo-site direction. This device has been applied to a number of locomotives onthe Boston & Albany Railroad, and also to a small experi-mental stationary engine, and tests have been made with both,which show not only a very material diminution of compres-sion, but indicator diagrams also showed that the expansionline was raised and the back pressure lowered. The rea-sons for the latter are somewhat obscure. The stationary en- - .
