摘要： A mechanical seal for preventing the leakage of fluid through the rotary sliding contact surfaces, in which a contact surface is provided with a plurality of fine one-way grooves having outer closed end portions. The fine grooves which are inclined outwardly and rearwardly to the relative rotation can be formed in the sliding contact surface of either the rotating member or the stationary member. If the fine grooves are formed radially or inclined outwardly and forwardly, the fine grooves may be formed in the sliding contact surface of the rotating member. The mechanical seal having such fine grooves in the sliding contact surface gives a quite good sealing effect because, during the rotation of rotating members, the leakage flow of the pressurized fluid or a mixture of liquid and gas that is sealed in on the outside thereof toward the external gas existing on the inside thereof, can be avoided in the sliding contact surface gives a quite good sealing effect since the flow of fluid from the outside to the inside of the rotating members during the rotation thereof can be avoided. In another embodiment of the above mechanical seal having the fine grooves, the peripheral portion of at least one sliding contact surface is somewhat raised in the direction of the axis of the rotary shaft so as to increase the contact pressure between the contact surfaces, thereby enhancing the sealing effect during the stoppage of the rotating members. Therefore, the sealing effect in all the use conditions can be much improved.

摘要： A mechanical seal comprises a seating ring and a follower ring. The seating ring receives therethrough a rotatable shaft and forms a stationary member and the follower ring is rotated together with the rotatable shaft in sliding contact with the seating ring. The seal is serviceable for avoiding the leakage of pressurized sealed fluid from the outside of the sliding contact portion between both the rings to the inside thereof. At least one of the sliding contact surfaces of both the rings has an outside raised portion along the periphery of the sliding contact surface. The raised portion is swollen in the direction of the axis of the rotatable shaft as compared with the inside portion of the sliding contact surface. Since the contact surface pressure in the peripheral portion of both the rings becomes high at the normal temperature by the provision of the outside raised form, the sealing effect can be improved especially during the stoppage of the follower ring. When the follower ring is subjected to the frictional heat due to its rotation, the follower ring is deformed in the direction in which the contact surface pressure becomes even. Therefore, the effect of sealing during the rotation is also improved. ,,pThis is a continuation, of application Ser. No. 133,713 filed Mar. 25, 1980, in turn a continuation-in-part of application Ser. No. 895,072, filed Apr. 10, 1978 both of which are now abandoned.
摘要翻译：机械密封件包括座环和从动环。座环通过可转动的轴接收并形成固定构件，并且随动环与可旋转轴一起旋转，与座环滑动接触。密封件可用于避免加压密封流体从两个环之间的滑动接触部分的外部泄漏到其内部。两个环的至少一个滑动接触表面具有沿着滑动接触表面的周边的外部凸起部分。与滑动接触表面的内部相比，凸起部分在旋转轴的轴线方向上膨胀。由于通过设置外部凸起形状，两个环的周边部分的接触表面压力在常温下变高，所以特别是在从动环停止期间可以提高密封效果。当从动环由于其旋转而受到摩擦热时，从动环在接触表面压力变得均匀的方向上变形。因此，旋转时的密封效果也提高。
