Abstract

Improvements in pipe joints, characterized by comprising a tubular element provided with a bore, one end of which is prepared to receive the end of the tube and comprises an inner part of a diameter such that it receives the end of the tube with a free but relatively tight fit. narrow; an intermediate part of a practically cylindrical shape and diameter appreciably greater than that of the tube, to receive a sealing ring of the toric type, and with a projection between the mentioned intermediate part and the mentioned internal part, and a tapered outer part that progressively increases in diameter from said intermediate part to the adjacent end of the tubular element; a cooperative clamping element having an annular portion prepared and arranged to meet around the tube beyond the aforementioned end of the tubular element, and to draw towards the latter during the clamping operation; said annular part has a frusto-conical circumferential inner surface, with its end of greater diameter adjacent to the tubular element; an understandable sleeve provided with a frusto-conical outer surface prepared to fit inside the frusto-conical bore of the annular part, and arranged to grip the part of the tube that passes through it, when the fastening element is dragged towards the tubular element; the outer diameter of the larger diameter end of the casting is such that its movement during the clamping operation will be limited by its adjustment directly or indirectly with the adjacent end of the tubular element; and an annular spacer in the form of a crown prepared to be positioned around the part of the tube comprised between the larger diameter end of the sleeve and the larger diameter cylindrical portion of the bore of the tubular element and having such an outer diameter as to form a free slip adjustment inside that top diameter part; the axial length of the spacer piece is such that during the coupling of the organs it will act to move the sealing ring of the O-ring to its closed position inside the aforementioned upper diameter part, around the adjacent external surface of the tube.
