QUICK TYPE FEED TUBE COMBINING STRUCTURE

摘要

A quick type feed tube coupling structure is provided to drastically reduce the process time and lower a production cost by simply force fitting a feed tube into a plate type curved taper plate fixed on a plug. A coupling structure of a feed tube for auxiliary hydraulic power steering device has a feed tube(340) inputting and outputting the power steering oil by using a cylinder tube. A plate type curved taper plate(310) has an opening part(315) on one side and has inclined surfaces on inner and outer circumferences. A plug(320) has a fixing sill(327) for fixing a lower part of the taper plate on an upper surface of the plug. The feed tube is fitted into an inner circumference of the plug. A flare tube fitting(330) has inner grooves for accommodating the taper plate. An o-ring(360) for preventing the leakage of the power steering oil is installed between the outer circumference of the feed tube and the inner circumference of the flare fitting tube.
