く確保されねばならない。This pulp rotating device is also used in automobile and construction engines, but when used in marine engines, it exhibits the effect of greatly extending the life of the engine knob. When a ship sails at sea, engine trouble can be fatal. Large ships with repair capabilities can self-repair while at sea, but small and medium-sized ships without repair capabilities cannot self-repair while at sea. Seven of these problems include a burnt-out blowout under the engine's 9-lb exhaust valve. The combustion temperature under the cylinder during the engine combustion process is not uniform, and therefore the temperature distribution under the exhaust valve umbrella is also not uniform. Since marine engines often use inferior fuel oil, ash in the fuel and sludge generated after combustion adhere to the face of the pulp and the seat of the valve seat, forming deposits. Since this deposit prevents the heat of the i4 pulp cap from being transferred to the cylinder head side, the temperature of the pulp cap rises and burnout occurs on the face surface. This process/gin pulp, especially when a rotating device is installed on the exhaust valve, equalizes the temperature of the valve cap, and by activating it every time the valve lifts, there is always a new level between the face and seat surfaces.
- Because they come into contact at different positions, it is a good idea to eliminate and clean any deposits that occur, improve heat transfer, maintain a good contact surface, and greatly extend the life of the exhaust valve. demonstrate. When the lifespan of the exhaust valve is extended, the lifespan of the valve rotation device used must be greater than the lifespan of the exhaust valve.

A retaining ring 13 is fitted into the groove at the bottom of the scar (51) and is engaged with the lower white surface of the retainer 8 to hold the cap body 5 and the retainer 8 in an assembled state. As shown in Figure S, Sollace 6 has V
It has a substantially square shape with two outer circumferential corners 6I, and the outer diameter of the outer circumferential corners 6I is somewhat smaller than the outer diameter of the retainer 8. The retainer 8 has a circular wall 8I, and the outer peripheral corner 6 of the peel-off race 6
The recess 8' is provided with a recess 8' for receiving the l-rail race 6 with a small gap, and the wall of the recess 8 is formed by a cut-out inner surface 8'II having a square shape corresponding to the shape of the l-le race 6.

心の作用で戻る。While the valve I is pushed down and opened by the action of the lift rod 12, the valve is rotated by this valve rotation device. That is, in FIGS. 3 and 7, the pre-valve opening pole 9 is located on the shallow side of the groove bottom A/ in the groove of the cap body 5, and while the valve 1 is pushed down and the valve is opened. The load on the valve springs 14 and 15 increases to deflect the disc spring 7 and push up the pole race 6. Therefore, the pole 9 is displaced from the shallow slope side of the groove bottom A' to the deep slope side against the action of the ball spring 10. At this time, the cap body 5 opens in the direction of arrow B. When the cap main body 5 rotates, the valve 1 is rotated via the lever 11. While the valve is rotating, the tail race 6 also partially 9
The cap body 5 tries to rotate in the direction opposite to the arrow H due to mutual friction between the cap body 5 and the cap body 5, but the outer peripheral corner 6I hits the cut-out inner surface 8'' of the circular wall 8' forming the recess 8' of the retainer 8 and rotates. During the rotation of the valve, the ball race 6 also tries to rotate in the direction opposite to the cap body 5 as shown by the arrow H due to mutual friction with the balls 9, but the outer peripheral corner 6I constitutes the recess 8# of the retainer 8. Rotation is stopped by hitting the cutout inner surface 8'' of the circular wall 8I. When the valve opens, the load on the valve springs 14 and 15 decreases, and the countersunk spring 7 also scoops out the deflection. Returns due to the action of the Nigaru spring core.
この時が一部げね10のばね力は微小であるからキャッ
プ本体5に回転を興える力とはならず、従って弁閉時ハ
過程下はバルブ1は回転せず概ね垂直に着座する。At this time, the spring force of the spring 10 is so small that it does not create a force that causes the cap body 5 to rotate. Therefore, during the valve closing process, the valve 1 does not rotate and is seated approximately vertically.

て接触部における破損の間順は全く生じない。As described above, according to the present invention, the outer peripheral corner portion formed between one adjacent side of the square is fitted into the four parts of the retainer formed between the similarly shaped cut surfaces. Since the pole race is engaged and held by the retainer, the action of stopping the same rotation of the pole race every time the valve is rotated is reliably performed with extremely high reliability. Moreover, when the sole race is rolled and fixed, the outer corner comes into line contact with the cut surface of the recess, so concentration of stress is avoided, and the outer corner and cut surface can sufficiently withstand high stress. Therefore, no sequence occurs during failure at the contact area.
