Connection coupling for hydraulic high-pressure hoses with connection parts or devices with the interposition of hydraulic constructional units such as, for example, non-return valves

摘要

A connection coupling (1) for hydraulic high-pressure lines with connection parts or devices (2) with the interposition of hydraulic constructional units (7) such as, for example, non-return valves has a flange (20, 21) engaging over an end piece (33) of the high-pressure line and of the constructional unit. This flange can be tightened against the connecting parts or devices by means of flange bolts (13). The constructional unit is centred by the flange bolts, which are situated at the outside. The flange bolts form the corner points of an imaginary square. The body of the constructional unit (7) has a shape which prevents it from rotating relative to the flange bolts. <IMAGE>
