摘要

The multi-way valve for an excess pressure system, especially for switching a CO2 air conditioning system between two modes of operation, has a row of chambers with individual connections (3, 4, 5). A valve slide (20) is mounted on a shaft (29) in a blind bore (28) so that it lies entirely in the internally pressurised region of the valve casing (2).
