Abstract

A thermal expansion valve for a refrigeration system comprises a working element with a diaphragm clamped between a cover plate and a cover ring. The diaphragm is a multiple-diaphragm comprising two or more individual diaphragms. This makes the multiple-diaphragm more flexible than a single diaphragms and increases the lifetime of the diaphragm. The individual diaphragms are separated by an anti-friction layer to protect against tear, the anti-friction layer can be grease or oil placed between the individual diaphragms or it can be a layer of coating on the diaphragms.
