摘要:
An internal combustion engine valve, of the type cooled by circulating a fluid in channels provided in the valve stem and head, and comprising in combination, means known per se for rotating the valve during its opening and/or closing motions, and a rotary joint connecting the channels of the valve stem to cooling fluid supply and return conduits.
摘要:
A valve rotating device for incrementally rotating a valve, particularly a valve in an internal combustion engine, the device including a housing arranged to seat a valve spring thereon, a retainer cap received within the housing, a spring washer having its inner periphery bottomed on the retainer cap and shiftable means acting between the spring washer and the retainer cap to incrementally rotate the retainer cap during axial movement of a valve stem within the housing, the spring member and the housing each having complementarily shaped straight sided portions preventing relative rotation between the two. The device of the present invention may also include a raceway located between the spring washer and the shiftable elements.
摘要:
A valve rotator having a spring washer interposed between a spring retainer collar and a retainer cap, a plurality of radial ball-ramps being provided in the retainer cap with a ball positioned in each of the ramps in rolling contact with the spring washer, the balls being retained therein and biased radially inward by means of an annular spring engaging all of the balls.
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.
