3. Spiral Groove Technology (1)
Conventional shock absorber
Throttle bores squeeze the oil out
Enormous operational demands of the oil through force-diverting and high velocities of hitting
Pressure peaks generate vibrations and reduce life-cycle / operating life
The amount of throttle bores affect the damping behavior, which limits the energy-consumption

4. Spiral Groove Technology (2)
PowerStop
The exhausting-channel is directly inserted in the piston as spiral groove
The machanical demand / strain of the oil remains low because of the rotary rising spiral groove
The section form allows a continous throttle activity and guarantees a smooth damping
Result: Maximum energy consumption by the entire damping stroke

5. Spiral Groove Technology (3)
Hydrostatic piston guidance by spiral groove technology
The symmetric axis of the integrated spiral groove produces during the damping process a hydrostatic slide bearing between piston and bushing
The sliding film separates the moveable elements during damping process
Long life-time, maintenance-free and reliability guarantee a high production safety

6. Ideal Damping Characteristic
PowerStop approaches with its damping course the ideal line of a shock absorber
By the special sectioned groove a smooth energy absorbtion will be started, the variation of the braking power is low
An exact positioning will be ensured also with extreme quick damping cycles with a short stroke
The characteristic curve of the spiral groove shows a continous course of the throttle cross-section over the entire piston stroke
In each piston position an ideal limit is realized and the energy consumption optimized
The masses to be moved can be smoothly and safely positioned, also with slow speed
However, throttle bores are producing a graduated characteristic curve with strong variations in the energy consumption
