    摘要： A ROTATING DEVICE FOR POPPET-TYPE VALVES INCLUDING A SPRING WASHER AND A PLURALITY OF SPRAGS POSITIONED BETWEEN FIRST AND SECOND PARTS, ONE OF SAID PARTS BEING INTERCONNECTED FOR ROTATION WITH THE VALVE. DEFLECTION OF THE SPRING WASHER ON THE VALVE OPEN STROKE CAUSES THE SPRAGS TO PIVOT FROM A FIRST TO A SECOND POSITION RELATIVE TO THE SPRING WASHER, PRODUCING ROCKING MOVEMENT OF THE SPRAGS AND ROTATION OF THE VALVE. THE SPRAGS ARE MOUNTED ON A RESILIENT DEVICE WHICH ENCIRCLES THE VALVE STEM AND NORMALLY BUT YIELDING HOLDS THE SPRAGS IN SAID FIRST POSITION.
