This is clearly shownat one end of its stroke. Two sets ofpiston rings are fitted to this trunkpiston, and the intermediate portion ofthe piston is provided with an annularring which bears lightly against the cyl-inder wall. Admission of steam is pro-vided for through ports bb in the endcovers of the cylinder.
