  • SEAL
    Publication number: 20190203837
    Abstract: A seal, in particular for a fluid line connector, includes: a tubular body with an inner surface, an outer surface, a first axial end, and a second axial end; a first elastomeric layer arranged on the inner surface; and a second elastomeric layer arranged on the outer surface. In an embodiment, the first elastomeric layer extends over the first axial end of the tubular body and merges into the second elastomeric layer.

  • Air conditioner with internal heat exchanger and heat exchanger tube therefor
    Patent number: 6883601
    Abstract: An air-conditioning system for a motor vehicle contains a heat exchanger with a heat-exchanger tube that features a profiled central channel and outer channels grouped around the central channel. This heat-exchanger tube is suitable for the construction of counterflow heat exchangers. For this purpose, the heat-exchanger tube is to be cut to corresponding lengths and provided with corresponding end pieces. Such heat exchangers have proven to be light, pressure resistant, and effective.

  • Cooling device with a controlled coolant phase upstream of the compressor
    Patent number: 6637219
    Abstract: A fluid collector of a cooling device, which collects fluid carried along by the coolant in a reservoir, is arranged upstream of the compressor. The return of the fluid coolant, which can also contain oil, into the section leading to the compressor takes place via an inlet conduit. A control device regulates the reintroduction of the fluid via a regulating valve in such a way, that the vapor conveyed to the compressor does not contain any large fluid particles.
