Single-rod
Type of effect: single-rod cylinder

Single-rod cylinders are cylinders with a single-sided piston rod and thus have a large piston area for extending and an area reduced by the piston rod area for retraction.

The term single-rod cylinder is only really correct if the ratio of the working areas is 2:1. However, since this is often not the case, the term cylinder with a single-sided piston rod is more accurate.
