    摘要: A railway buffer capsule comprising a hollow cylindrical plunger slidably mounted in a cylinder. The cylinder is closed at one end. The plunger is closed at its outer end, and in its inner end is formed a fixed area orifice of flow restricting dimensions. A floating piston slides in the bore of the plunger and separates a liquid reservoir from the remainder of the interior of the plunger which comprises a gas containing space. A stepped piston has its larger diameter exposed to pressure in the reservoir and its smaller diameter end adapted to seat and close the orifice and be exposed to compression chamber pressure. The combination of the stepped piston and the orifice is a multiplier valve which multiplies the resistance of the compressed gas to lengthwise compression of the buffer.
