Expansion valve for use in refrigerant circuit that is flow throughable by fluid to cool battery in e.g. electrical vehicle, has throat part whose flow cross-section is controllable by movement of one component relative to another component

摘要

The valve (35) has a first throat part (2) forming a fluid inlet of a housing (1) or downwardly arranged in a flow direction (9), where the throat part comprises a constant flow cross-section. A second throat part (5) is arranged downstream to the first throat part in a flow direction and comprises a variable flow cross-section. The variable flow cross-section is controllable by a movement of a first component i.e. spring bush (4), relative to a second component i.e. stop sleeve (6), where the components are arranged in the housing.
