Expansion valve with force equalization

An expansion valve having an inlet opening, at least one outlet opening and first and second valve parts. The inlet opening is adapted to receive fluid medium in a liquid state. The outlet opening(s) is/are adapted to deliver fluid medium in an at least partly gaseous state to a flow path. The valve...

Beschreibung
Zusammenfassung:	An expansion valve having an inlet opening, at least one outlet opening and first and second valve parts. The inlet opening is adapted to receive fluid medium in a liquid state. The outlet opening(s) is/are adapted to deliver fluid medium in an at least partly gaseous state to a flow path. The valve parts are arranged movable relative to each other such that the mutual position of the valve parts determines a fluid flow between the inlet opening and the outlet opening(s). During normal operation, a resulting force acts upon the first valve part and/or the second valve part to press the first and second valve parts towards each other. The expansion valve having ability for reducing the resulting force acting upon the valve part(s). Thereby the valve parts can easier be moved relative to each other, and the force required in order to operate the valve is thereby reduced.
