Claims

[Scope of utility model registration request]

(1) A body with an inlet port connected to a pressure source, and a first outlet port and a second outlet port connected to the left and right air springs, respectively, and a body inside the body that is connected to the inlet port. The valve chamber is formed to communicate with the valve chamber, the valve seat is formed in the valve chamber, and the valve body is arranged in the valve chamber so as to sit on and off the valve seat. A plunger is slidably fitted inside the body so as to seat and separate the valve body, and a first outlet port and a second outlet are arranged on the outer periphery of the plunger at positions spaced apart from each other in the sliding direction. a first annular groove and a second annular groove formed to be connected to the ports, respectively, and a body so that one end of each groove is connected to the valve seat and the other end of the groove is connected to the first outlet port and the second outlet port, respectively. The plunger is connected to a first supply passage and a second supply passage opened in a first discharge passage and a second discharge passage opened in the first discharge passage, a discharge port interposed in the valve body so as to be connected to the first discharge passage and the second discharge passage, respectively; and an operating means for advancing and retracting the plunger. and an adjuster slidably and positionably threadedly engaged with the plunger and configured to cooperate with an operating means.

(2) A claim for registration of a utility model characterized in that the first annular groove and the second annular groove are sealed from each other by a sealing member interposed between the two grooves on the fitting surface of the plunger and the body. The leveling valve described in Range 1.

(3) A claim for utility model registration characterized in that the adjuster is configured to be screwed into a stud bolt installed in the plunger and fixed by a lock nut screwed into the stud bolt. The leveling valve described in Range 1.
