Abstract: The invention relates to a sealing ring (1) for sealing a piston rod comprising a retaining ring (2) having a circular inside diameter (M1) and a center axis (M) and comprising a plurality of sealing segments (3), which are supported in the retaining ring (2) in such a way that the sealing segments can be moved in a direction radial to the center axis (M), wherein each sealing segment (3) has a sealing surface (3a) that is oriented toward the center axis (M) and that extends in a curved manner in a circumferential direction (U) with respect to the center axis (M), and wherein each sealing segment (3) has two lateral sealing-segment guiding surfaces (3b) extending parallel to each other, wherein the sealing surface (3a) ends at one of the two sealing-segment guiding surfaces (3b) at both ends, and wherein the retaining ring (2) comprises a plurality of guiding segments (2a) arranged at a distance from each other in the circumferential direction (U), wherein each two guiding segments (2a) following each other i

Abstract: In accordance with one embodiment of the present disclosure, an apparatus includes a connection body and a connection element arranged at least partially within the connection body. The connection body is operable to couple to a first element in a link arrangement and the connection element is operable to couple to a second element in the link arrangement. The apparatus further includes a metallic spring system arranged circumferentially around at least a portion of the connection element. The metallic spring system is operable to compress in response to relative movement between the connection body and the connection element.

Abstract: A method and device are provided for sealing a first oil environment, which is located on a first side of a movable piston guided in a hollow chamber, from a second oil environment, which is located on a second side of the piston. The piston can move back and forth in the hollow chamber between the two oil environments in the axial direction by a piston stroke length (d). Two annular seal elements are disposed around the movable piston so as to sealingly contact the inner circumferential wall of the hollow chamber. The annular seal elements are spaced from each other by at least a distance (D) in the axial direction that is greater than or equal to the piston stroke length (d).

Abstract: The present invention is directed to a system for providing a fluid seal between relatively movable elements, including a hub or a drum and a piston. A groove for retaining a seal is defined in the periphery of one of the rotatable elements, and a spacer element is disposed between the seal and the groove. The seal is formed from a substantially non-deformable material, and the spacer element is substantially non-resilient. The mass of the seal and the spacer element, together with rotational forces acting on the seal and the spacer element, provide a seal between the relatively rotatable elements for preventing flow of fluid.

Abstract: A piston seal for sealing a high pressure hydraulic cylinder includes a rigid seal ring, an elastomeric energizer ring, and a mask structure. The mask structure is effective in decreasing explosive decompression of air entrapped under the surface of the elastomeric energizer ring that causes pitting and deterioration of the elastomer of the energizer ring by masking the energizer ring material from harmful ingress and egress of air.

Abstract: A piston ring assembly includes a piston, and at least one piston ring positioned within a piston groove. Stabilization and support of the piston is provided by a support arrangement, including at least one support member positioned radially between a back wall of the ring groove and the piston ring. The support arrangement desirably acts to accommodate transverse loads exerted upon the piston during normal operation, and can optionally be configured for enhanced sealing of gasses. Improved engine output and efficiency are achieved.
