Title: EXPANSION VALVE
Abstract:
The invention relates to an expansion valve (100) for reducing the pressure of a fluid flowing through the expansion valve (100) along a fluid flow path, wherein the expansion valve (100) has: at least one fluid inlet (101); at least one fluid outlet (102); a first valve element (10) having at least one first channel structure (11); a second valve element (20a, 20b) having at least one second channel structure (22a, 22b) and one third channel structure (23a, 23b), wherein the first valve element (10) and the second valve element (20a, 20b) can be moved relative to each other, wherein, in a first position of the valve elements (10; 20a, 20b), the first channel structure (11) and the second channel structure (22a, 22b) are aligned with each other and form a first fluid flow path having a first flow resistance between the fluid inlet (101) and the fluid outlet (102), and wherein, in a second position of the valve elements (10; 20a, 20b), the first channel structure (11) and the third channel structure (23a, 23b) are aligned with each other and form a second fluid flow path having a second flow resistance different from the first flow resistance between the fluid inlet (101) and the fluid outlet (102).
