Connection system for a tubular rail for high-pressure fluid and a system for reducing the size of the rail

Torna indietro

Abstract

In order to reduce the size of a tubular rail for a highpressure fluid, the rail (5) is obtained from a hollow body (6) with an external diameter (D) and an internal diameter (d), and has two terminal portions (17, 18), each provided with an external milling (31, 32) to favour gripping thereof. The millings (31, 32) have an external diameter (D') such as to ensure, together with a cylindrical portion (22, 23) of a coaxial element (19, 21), a radial strength at least equal to that of the hollow body (6). Made between the hollow body (6) and each cylindrical portion (22, 23) is a front connection. For this purpose, the cylindrical portion (22, 23) has a plane front surface (24, 26), whilst each terminal portion (17, 18) has an internal milling with an internal diameter (d') greater than the internal diameter (d) of the hollow body so as to house the cylindrical portion (22, 23) and so as to form an annular shoulder (27, 28). A washer (29, 30) of softer material is set between the annular shoulder (27, 28) and the front surface (24, 26).
