Types of Hydraulic Cylinders

The types of cylinders are: Double-acting (Fig. 7.14a) Single-acting, spring return (Fig. 7.14b) Double-rod (Fig. 7.14c) Tandem (Fig. 7.14d) Telescoping (Fig. 7.14e) The double-rod cylinder has the same annular area on both sides, so it develops the same maximum force in both directions for a given relief valve pressure. It also extends and retracts at …

Rephasing of Hydraulic Cylinders

When cylinders are connected in series, it is necessary to provide a feature for rephasing these cylinders when they are fully retracted. Otherwise, leakage will cause the downstream cylinder to not fully extend. An example of the need for rephasing is an agricultural implement (planter, cultivator, disk harrow, grain drill, etc.) that must be folded …
