Document Type and Number:
Japanese Patent JP2002508826
Kind Code:
A
Abstract:
The invention relates to a pressure connector for pipes, comprising a pressure fitting having at least one section that is bulged crosswise and which accommodates a sealing ring, in addition to a first cylindrical section connected thereto and facing the insert side, a second cylindrical section facing away from the insert side forming a stop and exhibiting a smaller internal diameter than the first cylindrical section, and a line pipe whose smooth end area comes to rest on the stop of the second cylindrical section of the pressure fitting once it has been inserted into said pressure fitting. A fixed, tight pressure connection is formed using a pressure tool with at least two pressure cheeks encompassing the pressure fitting upon closure. During pressing, the pressing cheeks act upon the annular bulge and the sealing ring fitted therein, in addition to the first cylindrical section of the pressure fitting. The invention provides that the steep running side (8) of the annular bulge (4) facing the second cylindrical section (9) runs into the above-mentioned section (9) in a rounded form, devoid of irregularities. The internal diameter (10) of the second cylindrical section is the same as the internal diameter (13) of the inserted line tube (3) with a tolerance width of plus one half of the thickness of the wall (15) to minus 1 x the wall thickness of the inserted line pipe (3).
