ABSTRACT:
A rotary pressure/purge valve for supplying pulsation free oxygen without the use of an interim oxygen storage tank in the nature of a surge tank or accumulator. This valve is comprised of an air chamber section and a center section, with the air chamber section having an inlet port for compressed air, and the center section having a plurality of passages therein, disposed at equal intervals from each other and with respect to a centerline common to both sections. First valves are operatively associated with first passage ends, and serve to control the entry of charging air into two adjacent passages at the same time. Second valves are operatively associated with second ends of the passages and serve to control the exit of purging air from the passages. A shaft on the centerline of the center section serves to operate the first and second valves, with the valves being set out of phases such that when a first end of a given passage is closed to the entry of charging air, the other end of that passage is open to a flow of purging air, and vice versa. At a given moment compressed air can flow in one direction through at least one of the first valves and an associated passage, contemporaneously with purging air flowing in a different direction through a different one of the passages. This valve is able to deliver oxygen of a particularly high quality direct to a patient/user on demand.
