Indretning til reduktion af trykpulsationer i hydraulikledninger

The damper has a damping volume (17) on the rear of a plate (9) which moves in a space and which separates the duct instantaneous pressure from the mean pressure of the hydraulic system. The rear of the plate is backed by a weak spring (15,17) to hold the plate in a mean reference position. The damp...

Beschreibung
Zusammenfassung:	The damper has a damping volume (17) on the rear of a plate (9) which moves in a space and which separates the duct instantaneous pressure from the mean pressure of the hydraulic system. The rear of the plate is backed by a weak spring (15,17) to hold the plate in a mean reference position. The damping volume is linked to the hydraulic duct by a flow restriction (23) and the spring can be backed by a gas spring. Loading of the plate controls the damping frequencies while an active damping can be provided by a servo drive acting on a movable wall section.
