"Get / method of damping of disturbance of fluid pressure device, performance driven by fluid and hydraulic steering arrangement for vehicles.Disturbances of pressure in the fluid actuation of a device performance (10) such as a vehicular power steering system.That give rise to noise or vibration discernible by users of the vehicle are accommodated in the hydraulic circuit including a damping hose (42) having a peripheral wall definingNE a space containing fluid cross section is not circular.Allowing such disturbances deformarem the format of the wall locally to vary the area of the cross section regardless of the stretching of the wall.The form of the hose suitable is that defining a cross section is elliptical or with parts of the wall opposite tending to close together without the pressure of the fluid.And preferably is disposed in the return line pressure lower (36) between the actuator driven by fluid (26) and a pump (30).Adjacent to the actuator when that is a source of noise or vibration to be damped.
