Abstract
PURPOSE: To materialize the permanent sealing free from leakage of oil, by inserting an instantaneously weldable pin into the oil feed port, and by welding this pin.
CONSTITUTION: The bellows damper unit consists of the orifice 9, the bellows 6 whose end part 8 is supported, and the outer shell 7 of the container's main body 1 internally holding tightly sealed oil; this bellows unit is attached to the oil feed port 2. This oil feed port 2 is made into a small diameter, and nearby its entry a bevel shape 11 is formed so as to be easily, instantaneously meltable. Into this oil feed port 2, a taper pin 3 of about 1mm diameter is inserted, and the welding heat is given to the center of the protruding head of this taper pin 3, which is then instantaneously welded to the port 2. Hereupon, a severe dimensional tolerance is required for the diameter of both of feed port 2 and pin 3 on the reason of securing the sufficient molten metal from the pin 3. Therefore, a headed pin instead of the taper pin 3 can be used and welded to the port 2 as well as the protruded taper pin 3.
