Claims

1. IN RESPIRATOR PUMPING APPARATUS COMPRISING A ROTARY BLOWER ADAPTED TO BE CONNECTED TO A RESPIRATOR DEVICE IN FLUID FLOW COMMUNICATION THEREWITH FOR RHYTHMICALLY VARYING FLUID PRESSURE THEREIN FOR INDUCING BREATHING, SAID RESPIRATOR DEVICE BEING ADAPTED TO ENGAGE A PORTION OF THE PERSON'"'"''"'"'S BODY FOR EFFECTING BREATHING AND SAID APPARATUS COMPRISING A BLOWER FOR SUPPLYING PRESSURE FLUID TO SAID DEVICE, THE COMBINATION WITH SAID BLOWER OF ROTARY VALVE MEANS FOR CONTROLLING THE FLOW OF PRESSURE FLUID TO AND FROM SAID DEVICE TO PROVIDE A PERIOD OF INHALATION OF THE BREATHING CYCLE WHICH IS MORE RAPID THAN THE PERIOD OF EXHALATION OF THE BREATHING CYCLE, SAID ROTARY VALVE MEANS COMPRISING A STATIONARY VALVE MEMBER AND A ROTARY VALVE MEMBER MOUNTED FOR ROTATION IN SAID STATIONARY MEMBER, MEANS FOR DRIVING SAID ROTARY VALVE MEMBER, SAID ROTARY MEMBER HAVING A PASSAGE IN FLUID FLOW COMMUNICATION WITH SAID DEVICE AND SAID STATIONARY MEMBER HAVING A PASSAGE IN FLUID FLOW COMMUNICATION WITH SAID BLOWER, SAID STATIONARY MEMBER HAVING ANOTHER PASSAGE IN FLUID FLOW COMMUNICATION WITH THE ATMOSPHERE, EACH OF SAID PASSAGES IN SAID STATIONARY MEMBER BEING IN COMMUNICATION WITH SAID PASSAGE IN SAID ROTARY MEMBER AT PREDETERMINED POSITIONS, RESPECTIVELY, OF SAID ROTARY MEMBER, WHEREBY IN ONE POSITION OF SAID ROTARY MEMBER SAID BLOWER IS IN COMMUNICATION WITH SAID DEVICE TO SUPPLY PRESSURE FLUID THERETO AND IN ANOTHER POSITION OF SAID ROTARY MEMBER SAID DEVICE IS IN COMMUNICATION WITH THE ATMOSPHERE FOR TRANSMITTING PRESSURE FLUID THERETO, AND AN ADJUSTABLE VALVE MEMBER POSITIONED BETWEEN SAID STATIONARY VALVE MEMBER AND SAID ROTARY MEMBER AND HAVING FLUID PASSAGES DISPOSED RELATIVE TO SAID FIRST MENTIONED FLUID PASSAGES FOR VARYING THE RATIO OF THE PERIOD OF INHALATION TO THE PERIOD OF EXHALATION OF THE BREATHING CYCLE.
