SHOCK ABSORBER COMPONENT FOR RAILWAY CAR TRUCK

摘要

Railway transport buffer according to the present invention, in the rolling stock buffer having a piston valve for fluid to separate the inside of the filled cylinder to the compression chamber and the tensile chamber, the piston valve, a first inlet at the bottom of the inside of the body is is formed through in the compression chamber, the compression side flow path first outlet at the top of the perforated formed with the tensile chamber, and a second inlet at the top of inside of the body is formed through in the tensile chamber, the second outlet from the lower end that the tensile-side flow path which penetrates formed in the compression chamber, the respectively mounted within the compression side flow path and the tension-side flow path, mutually in the opposite one closed end is blocked with the first inlet and the second inlet conditions inserted and, after the one closed end is formed concavely on the outer periphery of the plunger and the plunger is formed with the inlet passage to be opened by the lifting stroke when the side It extends along a predetermined curvature, to guide the stroke when the fluid to be introduced through the inlet passage by the curve includes a guide groove for moving to the side of the compression side flow path or the tension-side passage.;
