Abstract: The present invention relates to a branch pipe connection for connecting a branch pipe to a lightly constructed underground sewage and drainage pipe. The connection includes a locking ring and a sleeve that are arranged against one another and can be tightened in their axial direction. The connection further includes a support flange. The locking ring has a slit by means of which the locking ring can be placed inside the underground sewage and drainage pipe through a hole made for the branch pipe from outside the underground sewage and drainage pipe. The pipe connection also comprises a sealing that is arranged to extend from the inner surface of the underground sewage and drainage pipe as far as the sleeve. A compact, dismountable connection for improving the ring stiffness of the underground sewage and drainage pipe is produced in this way.

Abstract: A coolant pipe connecting coupling in which a coolant passage is bent perpendicularly around a connecting portion has a low height connecting coupling and can reduce manufacturing costs. The coolant pipe connecting coupling includes a fixing block fixed to a connecting object by a bolt and a coolant pipe supported while being inserted into the fixing block. The coolant pipe is bent with an approximately zero bending radius. While at least an inside surface of the bending portion of the bending portion is received by the fixing block, the fixing block and the coolant pipe are fixed together. Therefore, a dimension of a connecting surface of the fixing block and the coolant pipe, that is, the height of the coolant pipe connecting coupling is set to be small. A coolant passage bent perpendicularly is not formed inside the fixing block, but coolant flow is bent perpendicularly by bending of the coolant pipe. Thus, manufacturing cost of the coolant pipe connecting coupling can be reduced.
