Abstract
A dashpot with an inner cylinder ( ) accommodated in an outer cylinder ( ), and a piston ( ) traveling back and forth inside on the end of a piston rod ( ) and separating the inner cylinder into two chambers ( & ). The piston rod enters the cylinders through a hole at one end that seals it off and positions it. The outer cylinder is provided with a base ( ) at the end opposite the end with the hole. The inner cylinder is centered along the axis of the outer cylinder at each end. The cylindrical gap ( ) between the two cylinders is provided with a fluid-accommodating compartment ( ) and, toward the base, a port ( ) opening into the adjacent chamber ( ). The chamber accommodates, preferably above the port, a vent ( ). The mutually contacting ends of the cylinders are hot or cold welded together at the base end or at the end remote from the base.
