The present invention relates to a flow adjusting device () for a shock absorber for a vehicle, the shock absorber comprising a cylinder () and a piston () dividing the cylinder into at least a first and a second working chamber (). The flow adjusting device is adapted to control at least a first damping medium flow (F) and a second damping medium flow (F) adapted to flow from at least one of the working chambers and comprises at least a first valve (), adapted to control the first flow, and a second valve (), adapted to control the second flow. The first valve and said second valve are jointly adjusted. The present invention further relates to a shock absorber comprising such a device and a front fork comprising such a shock absorber.

Flow adjusting device

A device adjusts the rotational damping of a steering device such that the rotational damping varies depending on whether the rotational motion about a steering axis is caused by a force acting on the steering device of the vehicle or a force acting on the part(s) of the vehicle contacting the ground. The flow of hydraulic fluid in the steering damper partly or wholly is adjusted by a main valve unit that is coupled together with both an attaching part and a steering device. The opening area of the main valve unit is determined by a relative motion between the attaching part and the steering device such that the flow of the hydraulic fluid in a direction from and to the respective damping chambers of the steering damper is controlled depending on the cause of the rotational movement.
