Abstract:
A vehicular roll stabilizer for a vehicle with air spring suspension between the axles and body, comprising:a roll sensing valve configured and dimensioned to be traversely and centrally mounted on the vehicular body, said valve receiving compressed air from an air tank to adjust a level of compressed air respectively supplied to left and right air springs; and left and right roll sensing rods operatively connecting said roll sensing valve and axles; wherein said roll sensing valve includes a valve body defining an inlet for connection to the air tank; left and right connecting holes connected to the left and right air sprints and an air outlet exposed to the atmosphere; left and right roll sensing levers connected to the left and right roll sensing rods; left and right shafts rotatably supporting the left and right roll sensing levers on the valve body; left and right rotors rotatably coupled to the left and right shafts within said valve body for switching a communicated state of the air inlet, the air outlet and the left and right connecting holes, and wherein said valve body includes: an air inlet hole for supplying air from said air inlet to the left and right rotors; an air outlet hole for discharging air from said left and right rotors to said air outlet; and left and right passages connecting said left and right connecting holes to the left and right rotors oppositely formed at right angles each from the air inlet hole and the air outlet hole and wherein the left and right rotors are formed with three arched holes, each spaced apart at about 120 degrees, such that said air inlet hole, said air outlet hole and left and right operational holes are switched in communicated states thereof by overlapping of arched long holes in response to rotation of said left and right rotors.
