Technical description
For tensioning and releasing the valve cap, oil is pressed into the gap between the tensioning cap and the piston via a quick lock coupling and a bore behind the coupling. This somewhat elongates the bolts.This elongation is compensated by turning the ring nut up against the tensioning cap. After releasing the oil pressure the system is tightly tensioned.
For releasing the valve cap the ring nut is turned towards the valve cap. When the oil pressure is released, the nuts can be easily unscrewed.
