Abstract

Described is a hydraulic delay device 100 comprising a fluid chamber 102, a first movable part 104 being movable in the fluid chamber a second movable 106 part the second movable part being movable in the fluid chamber, the first movable part defining a first flow path the second moveable part defining a second flow path and a third flow path where in a first movement state the first flow path is fluidically coupled with both the second flow path and the third flow path wherein in a second movement state the first flow path is fluidically coupled with the second flow path and is fluidically decoupled from the third flow path thus resulting in a delayed movement of at least one of the first moveable part and second moveable part.
