Abstract
A slide type valve (V) for regulating a gas generating system (10) that has at least a first and a second gas concentrating bed unit (12, 14) includes an outer body (120) with a slide face (106) having at least three open ports (130, 132, 134) communicating with an interior cavity (136) formed in the outer body (120). A vent port (132) and at least two bed ports (130, 134) are adapted to communicate an air flow with a gas concentrating bed unit (12, 14). The vent port (132) is formed between two bed ports. A slide block (100) having an essentially flat face (146) slides along the slide face interior surface (142) of the outer body (12) and has an interior cavity (148) and a first and a second opening (150, 152). The slide block slide face (146) has a closing portion (104) positioned between the first and second openings (150, 152). A controller (C) moves the slide block (100) between a first state (S1) and a second state (S2) for desired air flow.
