ABSTRACT:
A cylinder body has a bore and an annular recess formed therein. One end of the recess is in communication with the bore and the opposite end of the recess is permanently closed. An inlet and an outlet are in communication with the bore. A piston reciprocates within the bore and has an annular skirt which fits within the annular recess. The skirt compresses air when the skirt moves toward the closed end of the recess to form an annular seal of compressed air between the skirt and the closed end of the recess.
