Abstract: A sealing ring, in particular a radial shaft sealing ring or a rod sealing ring, can be used for sealing a sealing gap which is arranged between two machine elements. The sealing ring comprises an elastically deformable polymer material and a supporting ring which is embedded in a positively locking manner in the polymer material at least in sections. The supporting ring is configured as a 3D-printed part with a multiple-layer construction of its material at least in sections. The material of the supporting ring has a greater modulus than the polymer material. The supporting ring can be widened elastically in a radial direction with respect to the center axis of the sealing ring, and has dimensionally stable first ring segments which are connected to one another in an articulated manner in the circumferential direction of the sealing ring.

Abstract: A seal arrangement has two machine parts movable toward one another along or about a movement axis. One of the two machine parts forms a seal holding structure and the other forms a sealing surface. A sealing device between the two machine parts is arranged on or in the seal holding structure, wherein the sealing device includes a sealing element and a pre-tensioning element which is separate from the sealing element and by means of which the sealing element is tensioned in the radial direction against the sealing surface of the respectively other machine part. The sealing element is formed by an elastically deformable sealing film. On the sealing film side, the pre-tensioning element forms an embossed structure which presses into the sealing film where the sealing film bears against the sealing surface with a contact pressure progression which corresponds to the embossed structure of the pre-tensioning element.

Abstract: A rotary seal arrangement includes two machine parts arranged to be rotatable relative to one another about an axis of rotation. One of the two machine parts forms a seal retaining structure and the respective other of the two machine parts forms a sealing surface. A rotary seal is formed between the two machine parts with an elastically deformable retaining element of the one machine part and with a sealing element which bears in a sealing manner with a surface pressure against the sealing surface of the other machine part. The sealing element is designed as a helical spring sealing element arranged extending coaxially to the axis of rotation and arranged in a circumferential groove of the retaining element and twists proportionally to the frictional resistance between the helical spring sealing element and the sealing surface. Contact surface pressure is reduced between the helical spring sealing element and sealing surface.

Abstract: The present invention relates to compounds according to general formula (I); to compositions, including a pharmaceutical formulation and a combination preparation comprising one or more of the compound (s); to a process for their preparation; to uses thereof, including the use in the treatment or prevention of a viral infection or a Th17-associated inflammatory and/or autoimmune disease.

Abstract: A seal is disclosed, for sealing a seal surface (5) between two machine parts (6, 7) which move relative to each other, wherein a seal body of the seal (1) comprises a retainer piece (10), arranged towards the groove base in a groove (8) in one of the machine parts (7), a sealing part (11), arranged in the groove (8) facing the sealing surface and a resilient connector part (12) between the sealing part (11) and the retaining part (10). The seal (1) has a recess (21) between the retainer part (10) and the connector part (12) and a further recess (20) between the connector part (12) and the sealing part (11). The seal (1) has spacer elements (25), said spacer elements (25) extending into at least one of the recesses (20, 21), preferably at least into the recesses (20) between the sealing part (11) and the connector part (12).

Abstract: A sealing arrangement (14) has a housing gap, to be sealed, between two components (15, 16) and a seal (1) which consists of two interconnected sealing components (2, 3), a first extrusion-resistant, deformable sealing component (2) and a second more deformable sealing component (3). The first sealing component (2) has an abutment surface (6) facing the sealing surface (17) of the component (15), and a contact surface (9) for abutment on the other component (16). The second sealing component (3) abuts the first sealing component (2) and has an edge (4) projecting past the abutment surface (6). The first sealing component (2) can be pressed onto the sealing surfaces (17; 18) of the components (15, 16; 30, 31) to close the housing gap in response to system pressure. The second sealing component (3) can be sealingly pressed onto the sealing surfaces (17, 18). The sealing arrangement (14) is of simple construction and can produce an effective high pressure seal in Common Rail injectors or similar systems.
