SWING CYLINDER CUSHION OIL FLOW
(FIGURE 18 & FIGURE 19)
Swing Cylinder Operational Theory
Our swing cylinders are designed to cushion and
soften swing action.
Cross sections are shown in Figure 19 to give you a
view of the internal workings of the cylinder. Cushion-
ing action is obtained by incorporating restrictors in the
cylinders. When the boom is swung, the fluid is allowed
to flow normally until the cylinder nears the end of the
stroke, then fluid is forced through the restrictors to
obtain the cushioning action.
