Abstract
PURPOSE: To provide a vibration absorbing mechanism for use in power steering system, in which a pair of damper pistons are provided for exerting a reaction force to the rotation of handle shaft by the use of pressure difference of hydraulic oil, and further an orifice is formed in each piston for attaining smooth operation of the steering handle.
CONSTITUTION: When the steering handle is steered to the right, flow rate of the hydraulic oil is controlled by means of valve sleeve 17 and damper piston 32 is pushed downward by stopper pin 20. Another damper piston 31, on the other hand, is prevented from shifting upward by means of sleeve 25, so that it is detached from stopper pin 19. Here, if pulsating pressure is developed in hydraulic chamber 11, damper piston 32 is raised upward by the high pressure acted via surface 36, so that a reaction force is acted to the rotation of handle shaft 1. By the reaction force, flow rate of hydraulic oil is decreased by valve spool 17, and high pressure portions of the pulsating pressure are lowered, thereby cancelling the pulsating pressure. In turning the handle to the left, damper piston 31 acts in the same way as damper piston 32 whose operation has been described above in connection with the case in which the sterring handle is turned to the right.
