Abstract: A connector for two fluid conduits of different geometries includes a housing having a first and a second connection portion and a fluid channel fluidically connecting both connection portions; a locking element which can be coupled to the housing; and a seal which can be positioned between the housing and the locking element. The locking element and the housing can be positioned relative to one another with respect to the fluid channel such that a receiving portion for receiving the seal is formed between the housing and the locking housing. The first connection portion is designed to connect a first fluid conduit with an elongated cross-section and the second connection portion is designed to connect a second fluid conduit with a round cross-section.

Abstract: A device for degassing a liquid flowing in a liquid line is provided. The device has an inlet opening, an outlet opening, and a capillary element having an inner wall surface. The capillary element extends between the inlet opening and the outlet opening. The inlet opening is connected in a fluid-communicating manner to the outlet opening and is connected in a fluid-communicating manner to the liquid line. The inner wall surface has a material that is liquid-repellent for a liquid flowing in the liquid line. A device is thus provided for degassing a liquid flowing in a liquid line that reduces the time needed for degassing.

Abstract: A line coupling having a housing which has a tube connection piece and a housing head. A passage duct extends from a first opening, which is formed by the tube connection piece, to a second opening, which is formed by the housing head. A tube connection structure is arranged in the passage duct. The tube connection structure is connected in a form-fitting manner via first coupling means to a first end of an inner tube which extends out of the housing head through the second opening. The section of the passage duct between the first opening and tube connection structure and inner tube form a flow duct for fluid. A container is also disclosed having a container housing which forms a container hollow space and a container opening. The container opening is formed by an outwardly projecting connection piece, and has a line coupling.

Abstract: The disclosure relates to a connector for a fluid line which includes a tubular housing. A receiver for a connecting piece is present in the tubular housing. The receiver is surrounded by an integral, continuous rotary ring. The rotary ring is pretensioned for locking the connector into a locked position and is rotatable for unlocking the connector into a released position. At least one guide channel is configured in an outer envelope surface of the tubular housing. This guide channel has an inlet on a first front face of the tubular housing. The rotary ring is received at least partially in the guide channel.
