Claims31
A device for regulating a through-flow and expanding a fluid in a fluid circuit, the device comprising:
- a housing;
- and
- a valve element arranged in an interior of the housing which is movably arranged in a direction of a longitudinal axis relative to the housing, as well as at least one sealing element, wherein the valve element and the at least one sealing element are arranged oriented coaxially to the longitudinal axis, and the valve element is arranged abutting, in a closed condition of the device, the at least one sealing element and, in an opened condition of the device, forming at least one fully circumferential gap between the valve element and the at least one sealing element, wherein the at least one sealing element forms a sealing seat in connection with the valve element, and the at least one sealing element or the valve element has at least two sealing faces in a region of the sealing seat which are arranged spaced apart from one another in the direction of the longitudinal axis, wherein a respective groove is formed between the at least two sealing faces which are arranged adjacent to one another, and wherein a length of a first one of the at least two sealing faces is different from a length of a second one of the at least two sealing faces.
