Abstract

The invention relates to a closure system for pressure vessels, the closure consisting of a cover and of two clamp halves each of which can be moved into closing or open position by means of guiding elements. The clamp halves, the cover, and the pressure vessel housing being equipped with stop surfaces, the stop surfaces of the clamp halves being opposite to those of the cover and of the pressure vessel housing in closing position. The closure system is especially suitable in cases where an entirely automatic closing device is required for pressure vessels having an operating pressure of more than 10 bar. The clamp halves are connected by means of tensible flexible bearings to guiding elements to allow for a cover movement in axial direction. The tension of the flexible bearings is sufficient for automatic resetting of the clamp halves into zero position after depressurization of the vessel.
