Hose coupling for high pressure hydraulic hoselines of hydraulic system in manufacturing machine, has hose nipple in safety region with bulge, and press holder exhibiting uniform wall thicknesses in safety region and sealing region

摘要

The coupling (10) has a press holder (20) provided with a wall deformation unit (21) that is aligned and running radial to a high pressure hydraulic hoseline (11), in a safety region (A). A recess is provided at an outer side of the press holder in an area of the deformation unit. The deformation unit is made of material same as material of another wall deformation unit (24) in a sealing region (B). A hose nipple (31) in the safety region has a groove-like bulge (34) lying opposite to the former deformation unit. The holder exhibits uniform wall thicknesses in the safety- and sealing regions.
