PURPOSE:To abate the extent of frequency pulsating pressure by connecting a rubber hose to a space between a hydraulic pump and an actuator, setting up a steel pipe in the intermediate part, and connecting each of separate rubber hoses to the hydraulic pump side of this steel pipe and the actuator side. CONSTITUTION:In rubber hoses 10, 11, one end clamps a terminal fitting 13 by retightening a socket 12, and a nut 14 is clamped to this terminal fitting 13. The other end of the rubber hose clamps the terminal fitting by retightening the socket 12, and the rubber hose 10 is connected to the rubber hose 11 via a steel pipe 7 fixed to a nipple 13 of the terminal fitting by means of welding or retightening or the like. And the nut at the left is screwed in a high-pressure fluid delivery port of a hydraulic pump, while the nut 14 at the right as faced is screwed in an inlet of an actuator, thereby constituting a high-pressure pipeline for a power steering, If so. an areal expansion value at the time of pressurization of the rubber hose 10 at the hydraulic pump fluid outlet side is altered whereby pulsating pressure at the desired frequency is abatable. |
