Abstract
A slide type valve (V) for regulating a gas generating system () that has at least a first and a second gas concentrating bed unit () includes an outer body () with a slide face () having at least three open ports () communicating with an interior cavity () formed in the outer body (). A vent port () and at least two bed ports () are adapted to communicate an air flow with a gas concentrating bed unit (). The vent port () is formed between two bed ports. A slide block () having an essentially flat face () slides along the slide face interior surface () of the outer body () and has an interior cavity () and a first and a second opening (). The slide block slide face () has a closing portion () positioned between the first and second openings (). A controller (C) moves the slide block () between a first state (S) and a second state (S) for desired air flow.
