Beschrieben wird eine Vorrichtung zur Dichtung eines Ventils zur Steuerung eines Kühlmittels einer Verbrennungskraftmaschine eines Kraftfahrzeuges, das mit einem Ventilgehäuse (1) in ein Kühlsystem eingebaut ist, wobei das Ventilgehäuse (1) einlassseitig und/oder auslassseitig einen Dichtring (3) enthält, der eine Ringwandung (4) und eine von der Ringwandung (4) von einer Kontaktstelle (6) ausgehende, beanstandende Ringlippe (5) aufweist.
摘要:
A sealing ring (10) includes in a diametrical cross-section a body section (12), angularly spaced sealing legs (16) and (18) that extend from the body section (12) and angularly spaced sealing legs (22) and (24) that also extend from the body section (12). Each sealing leg (16, 18, 22, 24) extends to a beveled end (28, 30, 32, 34), respectively. Beveled ends (28, 30, 32, 34) form a seal with a surface when sealing ring (10) is subjected to compressive forces. Sealing legs (16) and (24) are coplanar. Sealing legs (18) and (22) are coplanar. A first centering leg (40) extends from the body section (12) and is between sealing legs (16) and (22). A second centering leg (44) extends from the body section (12) and is between sealing legs (18) and (24). The first and second centering legs (40) and (44) are coplanar.

Valve seats include a flexible arm portion configured to seal against a portion of a valve body of a valve. A ball valve may include such valve seats. Methods of forming a seal in a ball valve include forcing a first metal valve seat into sealing contact with a first end cap and a ball valve member with a first metal flexible arm member and forcing a second metal valve seat into sealing contact with a second end cap and the ball valve member with a second metal flexible arm member.
摘要:
An elongate seaming device (1, 2, 3) that includes a pair of deformable lips (13a, 13b, 32a, 32b) along its lateral edges and an attachment means (10, 210, 111, 31) for attaching the seaming device along a join between two adjacent surfaces. The lips (13a, 13b, 32a, 32b) are configured to deform against a respective surface on each side of the join along which the device is attached to provide a substantially continuous seam. The attachment means (10, 210, 111, 31) can be in the form of a spine (10, 210, 111). The spine (10, 210) may be L-shaped to receive and engage an upstand (5) and may include a thinned portion (11a) to enable it to be severed to accommodate tiles (7). The spine (111) may include engaging formations (111 a, 111 b) or barbs (211a, 211 b). The attachment means (31) may be in the form of an adhesive strip (31).
摘要:
A taped seal construction for a body part of a vehicle, with a seal with a main portion and a lip portion, the main portion being designed to extend on one side of the body part of the vehicle and the lip portion being designed to extend on another side of the body part of the vehicle thereby covering an edge of the body part, and a tape, the tape being attached to the main portion of the seal, wherein that the tape comprises a split liner.
摘要:
A sealing member including a body having a recess; one or more backups extending from the body and tapering over a length thereof; and a sealing element disposed in the recess, the element including one or more steps, each step being adjacent one of the one or more backups and on a surface of the sealing element intended to make contact with a target sealing surface.
