Stroke rate
The stroke rate is dependent on the minimum flow
opening, the volume of oil and the working and return
pressures. The connecting openings allow a working
stroke rate of up to 0.8 m/s. Although this is limited by
the extent to which the system heats up due to the
high stroke rates. The system temperature should not
exceed 60 °C.
Safety instructions
If the layout of the system gives the Force Cylinder an
excessive displacement volume due to excess over-
travel and/or seizing of the cylinder, the pressure in the
system can exceed the admissible value of 280 bar. In
critical situations, this effect will be counteracted by
the opening of a rupture valve at 517 bar.
The couplings are designed for a nominal pressure of
300 bar and 1000 bar rupture pressure.
On the gas side, the Accumulator is pressurised at 150
bar and is subject to Pressure Equipment Directive
97/23/EC.
To monitor safety during the process, we recommend
installing a control fitting as an additional check on the
gas side - see range of accessories.

Comments
The Accumulator and the Force Cylinder are pressure
vessels and as such are subject to the Pressure Equip-
ment Directive 97/23/EC.
During cutting and hole punching operations the nomi-
nal force of the Compact Cam should only be utilised
up to 75% to minimise impact during cutting which is
reinforced by the Accumulator. Impact during cutting
can be reduced by polished tool edges (e.g. roof
shape) and so downtime can be reduced.
Values other than those specified in the above table
may be accepted under certain circumstances or if
different stroke lengths, speeds and frequencies are
combined.
