Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An expansion valve comprising: an inlet opening adapted to receive fluid medium in a liquid state, at least one outlet opening adapted to deliver fluid medium in an at least partly gaseous state to at least one flow path, a first valve part and a second valve part arranged to be movable relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines a fluid flow between the inlet opening and e…
