Operating principle:
ADS shock absorbers for elevators are closed hydraulic components which
operate on the basis of oil displacement.
When the piston rod is pushed into the cylinder, the piston displaces the oil
through different sized holes which are progressively closed off.
As a result the speed of the piston rod proportionally decreases to the stroke
covered. The displaced oil from the volume of the piston rod is compensated by
an accumulator of nitrogen, which is above the oil.
During the stroke the pressure in the nitrogen is increased. When the mass is
released the piston rod is returned by the pressure of the nitrogen / return spring.
A plastic stop cap reduces the impact noise. The ADS-50 shock absorbers are
filled by a valve with nitrogen at 5 bar.
An oil sight glass allows easy visual check of the oil level.
For monitoring of the extended piston rod a limit switch according DIN-EN 50047
is built in. Depending on the type of ADS the limit switch is pushed in by the
protection tube (ADS-SR) or by the contact pin (ADS-ST).
