Stroke
The attainable working depend on many
factors, mostly stroke and load. In the diagram, the
upper range for each type represents the attainable
cycling frequency at low load, and the lower range
represents the attainable cycling frequency at high
load.
To attain the upper limit, time-leading control is ad-
visable.
A fitted advance movement cushioning arrangement
allows optimum balancing of stroke, cycle rate, and
mass.
