Abstract
A quick coupling for hoses or pipelines with a coupling sleeve (1), a plug-in nipple (3) and a sealing element (21) is proposed, in which the sealing element (21) is tensioned in the locked state and/or has a rectangular cross section so that the tightness and the diffusion resistance of the quick coupling according to the invention are improved.
Claims12
Quick coupling for hoses or pipelines with a coupling sleeve (1) having a first passage borehole (9), with a plug-in nipple (3) having a second passage borehole (18) and with at least one sealing element (21) located in the first passage borehole (9), characterized in that the sealing element (21) is tensioned in the axial direction (S3) in the coupled state of the quick coupling.
Quick coupling according to one of the preceding claims, characterized in that the quick coupling has a locking element (36) and that the locking element (36) has means (37) that interact with the plug-in nipple (3) or the pressure sleeve (23) for creating the tensioning of the sealing element or elements (21).
Quick coupling according to one of the preceding claims, characterized in that the sealing element (21) is an 0-ring.
Quick coupling for hoses or pipelines with a coupling sleeve (1) having a first passage borehole (9), with a plug-in nipple (3) having a second passage borehole (18) and with at least one sealing element (21) located in the first passage borehole (9), characterized in that the sealing element (21) has an essentially rectangular or square cross section.
Quick coupling according to one of the preceding claims, characterized in that the sealing element (21) and the pressure sleeve (23) are made in one piece.
Quick coupling according to one of the preceding claims, characterized in that the sealing element (21) is a four-lipped sealing ring or a multi-lipped sealing ring.
