Pipe connection means for the connection of crosswisely extending pipes to a longitudinally extending transport pipe

Claim 1

In a pipe connection means for connecting at least one transversely extending pipe to a longitudinally extending transport pipe, the pipe connection means comprising two connection parts attachable to each other including portions for sealingly engaging the transport pipe, thereby forming a connection unit; at least one flow channel in the connection unit leading to one region of the transport pipe wall, the transversely extending pipe being attachable in the one flow channel; at least one guiding channel in one of the connection parts, said guiding channel opening into said flow channel; and a rotatable valve body arranged for displacement within said guiding channel towards said one wall region; the improvement in which said valve body being provided with means defining a forward plane cutting edge for substantially tangential engagement with said transport pipe and piercing at least a portion of said transport pipe at one wall region and forming a recess tangential therein opening into said transport pipe when forwardly further displacing the valve body in said guiding channel, said recess rotatably accommodating the valve body and the valve body prevents movement of the connection unit relative the transport pipe; means arranged for terminating the guiding channel at a region beyond said recess, said means accommodating the wall portion cut out by said cutting edge; and said valve body being provided with means defining a through hole for providing flow communication between said transport pipe and said flow channel when said valve body is rotated about its longitudinal axis to a predetermined position in said recess.
