Abstract A device for sealing the space between two surfaces comprising an elongated body portion made of a flexible, resilient material such as rubber. The body portion engages in a recess in one of said surfaces. The sealing device further includes at least two rigid plate members seating in a recess in the body portion and having a portion projecting therefrom defining a channel and a sealing member mounted in said channel and projecting therefrom to engage the other of the sealing surfaces to be sealed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
A sealing device for an interspace between two surfaces, characterized thereby, that it incorporates a flexible, elongated body (7, 14) with a longitudinal recess (8), which body is intended firmly to engage against a first one of said surfaces, two plates (9, 10) having a form corresponding to the form of at least a part of said interspace and such profiles that they on one hand can be pushed into the said recess in said body for mutual positioning and on the other hand when pushed into said recess in said body between themselves define a channel (11), and a sealing member (12, 14a) intended to be fitted in said channel, in such a manner that it in the assembled position of the sealing device engages against the second one of said surfaces.
Claim 2
Dependent Claim
133 words
A sealing device for an interspace between two surfaces, characterized thereby, that it incorporates a flexible, elongated body (7, 14) with a longitudinal recess (8), which body is intended firmly to engage against a first one of said surfaces, two plates (9, 10) having a form corresponding to the form of at least a part of said interspace and such profiles that they on one hand can be pushed into the said recess in said body for mutual positioning and on the other hand when pushed into said recess in said body between themselves define a channel (11), and a sealing member (12, 14a) intended to be fitted in said channel, in such a manner that it in the assembled position of the sealing device engages against the second one of said surfaces.
Claim 3
Dependent Claim
51 words
A sealing device according to claim 1, characterized thereby, that one of said surfaces (5) is provided with a groove for the flexible, elongated body, said body and said groove thereby having such shapes that the body is compressed by the side surfaces of the groove when mounted in the groove.
Claim 4
Dependent Claim
118 words
A sealing device according to claim 1 for an annular interspace between a bore (4) in a housing and a member (3) disposed in the bore, characterized thereby, that the interspace is bridged by two flexible, elongated bodies (7, 14) each of which is arranged to enclose half of the circumference of said member and provided with two plates (9, 10) having a form corresponding to the form of each half of the interspace, and a sealing member (12, 14a) disposed in a channel between the plates, the ends of the bodies, the plates and the sealing members thereby being adapted to engage each other in a diametrical plane through the member (3) disposed in the said bore.
Claim 5
Dependent Claim
42 words
A sealing device according to claim 1, characterized thereby, that the sealing members (14a) in the channel between the plates and the flexible body (14) wherein the plates are pushed in have the same profile and are made of the same material.
