A communication system may also be provided to alert the driver via a remotely located computing device that the emergency brakes for the trailer need to be set.

Abstract: A piston valve assembly for a shock absorber is disclosed. In a high-frequency mode, a damping force control is achieved through an open passage that is always opened. In a low-frequency mode, a guide assembly moves downward due to an increase in a pressure of a first pressure chamber by a fluid moved through an inlet hole of the first pressure chamber. At this time, the guide assembly blocks the open passage and the damping force control is achieved through only a rebound passage. Consequently, it is possible to solve a fluid bottle neck through a passage formation. A disk is installed on the inlet hole to prevent a continuous increase in the pressure of the first pressure chamber, thereby effectively preventing the reduction of the damping force.

The valve seat side chamber and the opposite valve seat side chamber communicate via a communication passage and the valve seat side chamber and the flow path communicate via a throttle passage.
