ABSTRACT:
A sealing device for high pressures which comprises a seal located in the annular space formed between a revolving shutter and a coaxial surrounding seating therefor, the annular space being limited by four surfaces associated in pairs as front surfaces and rear surfaces, wherein the intersections with an immaterial semi-plane limited by the axis of the device of the two surfaces are a couple of straight-line segments forming a first acute angle whose apex occupies a rear position relative to the said segments, whereas the intersections of the two rear surfaces with the semi-plane are a second couple of straight-line segments forming a second angle less acute than the first and whose apex occupies a rear position relative to the second couple of straight-line segments.
