Dual Type Load Sensing Proportioning Valve for Automotive Braking System

摘要

The present invention relates to a dual-type load sensing proportioning valve of a vehicle braking device, the same pressure and the same hydraulic pressure start point acts on the rear wheel cylinder to prevent partial braking and to ensure steering stability. In the dual type rod sensing proportioning valve of a motor vehicle brake system, 30 is housed in one valve body 10 and is connected to the front and rear diagonal wheel cylinders as hydraulic valves as a valve on one side, the pistons 23 and 32. First communication holes 70 and 80 extending in the valve body 10 so as to communicate the cylinders 21 and 31 and the second outlets 72 and 82 from the front of the first and second communication holes 70. And a second communication hole 72 formed to penetrate the first communication holes 70 and 80 on both sides in a middle portion of the intermediate part 80, and slidably embedded in the second communication hole 72. Including a sliding piston 90 to form the first and second chambers It is configured to.
