摘要： To provide a hollow poppet valve having an improved heat reduction effect. In a hollow poppet valve (10) having a valve head (14) and a stem (12) integral with the valve head (14), the hollow poppet valve (10) is formed with an internal cavity S that extends in the valve head (14) and the stem (12). The internal cavity S is charged with a coolant (19) and an inert gas. The internal cavity S has a generally disk-shape internal cavity S1 and an internal stem cavity S2 formed in the stem (12) and connected to the internal valve head cavity S1 at a right angle. During a reciprocal motion of the valve (10), a vertical convective flow of coolant (19) along the axis L of the valve (10) is established at least in the internal valve head cavity S1, thereby enhancing its heat reduction effect.

摘要： OBJECT To provide a burring apparatus for a friction welding machine, capable of removing a burr created in friction welding immediately after the welding. MEANS FOR ACHIEVING THE OBJECT An inventive burring apparatus for a friction welding machine comprises: a clamp unit (25), provided at the front end of a horizontal main spindle (22), for holding the work piece W1 coaxial with the main spindle (22); a clamp unit (34) provided at the front end of a slide (30) that is movable to and away from the main spindle (22) in the direction of the axis L of the main spindle (22), the clamp unit (34) adapted to gripping the work (W2) coaxial with the slide (30); and a doughnut-shaped cutter (50) for shearing off a burr. The work piece W2 is moved forward together with the slide (30) through the doughnut-shaped cutter (50) ahead of the main spindle (22) until the work piece W2 comes into contact with the work piece W1 in rotation with the main spindle 22 so that the mated ends of the work pieces W1 and W2 are friction welded together on one side of the doughnut-shaped cutter (50) proximate to the main spindle (22), thereby forming a jointed work piece W. After the work pieces W1 and W2 are friction welded, the cutter 50 is moved over to the main spindle 22 Meanwhile, the burr w formed on the periphery of the jointed work is sheared off by the cutter. The jointed work piece W gripped by the main spindle (22) is then liberated from the main spindle 22, and the slide (30) is retracted to its home position. The chopped burr comes off the work piece W when the jointed work piece W is removed through the cutter 50.
