ABSTRACT:
A sealing device especially designed for sealing between the opposed flat surfaces of a stationary member and a rotary member. The device comprises a multiple seal ring composed of a plurality of annular seal elements of different diameter which are received in an annular groove formed in the rotary member. The seal elements each have a flat sealing face formed at one end for sealing contact with said flat surface of said stationary member and a conical sealing face formed at the other end for sealing contact with a conical bottom surface of the groove, the conical sealing face diverging in a radially outward direction toward the flat sealing face. The seal elements are each cut radially so as to provide themselves with a radially outwardly expanding force and closely fitted one over the other in a concentric relation with the radial cut portions of the respective seal elements being circumferentially displaced from one another for sealing the cut portions of the seal elements. The seal elements in use are caused under the action of their own expanding force to slide along the conical bottom surface of the groove so as to urge their flat and conical sealing faces into intimate sealing contact with the flat surface of the stationary member and the conical bottom surface of the groove. With the above construction, the seal between the flat surfaces of the stationary and rotary members is effected solely by the multiple seal ring without employing any additional means such as springs, O-rings, or the like and hence the sealing device is extremely simple in construction and highly durable.
