Abstract

A pressure vessel includes a housing having an interior and a passage communicating with the interior and being bounded by an inner circumferential surface. A separate plug is received in the passage. The plug has an outer circumferential surface juxtaposed with the inner circumferential surface. These surfaces define together at least one gap of relatively small cross-section. The gap extends lengthwise of the passage communicating with the interior of the housing.
