Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
PROCESS FOR THE CONTROL OF FEED TO A ROTARY PISTON TYPE ENGINE HAVING AN ADMISSION CIRCUIT WITH CHARACTERISTICS PROVIDING AN OPTIMUM LEVEL OF FEED FOR A PREDETERMINED SPEED OF THE ENGINE UTILIZING THE DYNAMIC EFFECTS OF THE FEED GAS IN VIBRATING STATE, THE PROCESS PROVIDING AN ELEVATED LEVEL OF FEED AT SPEEDS LOWER THAN THE PREDETERMINED SPEED FOR WHICH THE FEED IS OPTIMUM AND INCLUDING THE STEPS OF ADVANCING BY A GIVEN INTERVAL THE CLOSING AND OPENING OF ADMISSION IN THE CYCLE WHEN THE ENGINE SPEED IS LESS THAN THE SPEED OF OPTIMUM FEED, AND INCREASING THIS INTERVAL AS THE ENGINE SPEED DECREASES.
Claim 2
Dependent Claim
103 words

Claim 3
Dependent Claim
141 words
APPARATUS FOR CONTROL OF FEED OF A ROTARY PISTON TYPE ENGINE, WITH AN ADMISSION CIRCUIT PROVIDING AN OPTIMUM LEVEL OF FEED FOR A PREDETERMINED ENGINE SPEED UTILIZING THE DYNAMIC EFFECTS OF THE FEED GAS IN VIBRATING STATE AND PROVIDING AN ELEVATED LEVEL OF FEED FOR SPEEDS LOWER THAN THE SPEED OF OPTIMUM FEED, AND AN AIR ADMISSION PORT FOR THE ENGINE CONNECTED TO SAID CIRCUIT, COMPRISING A ROTATING OBTURATOR OPENING AND CLOSING SAID ADMISSION PORT, A SHAFT FOR SAID OBTURATOR, MEANS FOR COUPLING SAID SHAFT TO THE DRIVE SHAFT OF THE ENGINE, SAID MEANS INCLUDING ADJUSTMENT MEANS PROVIDING A DISPLACEMENT IN THE ANGULAR POSITION OF SAID SHAFT OF SAID OBTURATOR WITH RESPECT TO THE DRIVE SHAFT OF THE ENGINE, SAID DISPLACEMENT BEING MAXIMUM AT THE SPEED OF OPTIMUM FEED AND DECREASING WHEN THE SPEED DECREASES FROM THE SPEED OF MAXIMUM FEED.
