Abstract: A device for separating a gaseous and a liquid phase of a working medium and for storing the liquid phase. The device has a volume enclosing wall with closed end faces, an inlet and an outlet, as well as a suction pipe. A partition element is arranged within the volume, which divides the volume in a separation volume and a storage volume. The separation volume is formed above the partition element in a direction z of gravity, while the storage volume is formed below the partition element. The suction pipe opens into the separation volume.

Abstract: A device for storing refrigerant of a refrigeration circuit and a method of operating the device, in particular for an air conditioning system of a motor vehicle. The device has a housing having a volume-enclosing wall with an inlet for introducing a refrigerant-oil mixture, and an outlet, a refrigerant discharge line arranged in the interior of the housing with an inlet opening arranged above a liquid level of the refrigerant for receiving gaseous refrigerant, and a system for returning oil to a compressor having at least one through hole formed below the liquid level of the refrigerant, in particular below a filling level of the oil, in the refrigerant discharge line. In addition, at least one through hole formed in the refrigerant discharge line is formed with an adjustable through-flow cross section, which can be varied by means of a closing apparatus.

Abstract: An arrangement for fluid-tight connecting of lines including a first and second connection element. The connection elements are aligned with each other and connected by a fastening mechanism. The arrangement includes an intermediate element between the connection elements and a holding element and a second sealing element. A first sealing element is arranged in the holding element between the sealing surfaces of the connection elements. The holding element has a hollow wall with a first and second edge. The second sealing element is connected to the holding element on the second edge. The intermediate element includes an indentation extending from a first end to a second end formed near the first sealing element. The first end has a conical shape, wherein oppositely arranged side walls of the indentation rest on one another on the outer side of the sealing element.
