Spring–elastic axial seal for a gate valve
PATENTS Movable hydraulic seal
Sealing methods for a pulley bearing Applicant: Dayco Products Llc, USA A range of sealing methods for a pulley bearing are illustrated. These include elastomeric shields and also a V-ring seal that is located on both sides of the bearing. Patent number: WO/2011/019676 Inventors: A.E. Lannutti, R.J. Crist and M.J. Leis Publication date: 17 February 2011
Bimetallic static gasket Applicant: Federal-Mogul Corp, USA This refers specifically to multi-layer metal, exhaust manifold gaskets. The functional, sealing layer is made from a different metal to the carrier layers. In this way, a high-cost functional layer material is used only where it is necessary in order to reduce costs. In addition, the carrier layers can have raised projections formed from the carrier metal material, to set the level of the stopper layer. This further avoids the use of a carrier layer metal sheet that is excessively thick. Patent number: WO/2011/019792 Inventors: T.W. Swasey, C. Schenten, M. Bowman, J. Sas, C. Santiago, R. Prehn, T. O’keefe, M. Shirilla, T.O. Zurfluh and K.T. Roberts Publication date: 17 February 2011
Flat seal Applicant: Federal-Mogul Sealing Systems GmbH, Germany An exhaust seal for an internal combustion engine is described. It includes a single-layer sealing element, which is provided with an opening, and a carrier element that accommodates and guides it with play, and which is provided with through-holes for a fastening mechanism. The components that guide the sealing element project beyond the footprint of the carrier element, and the carrier element and/or the sealing element is provided with at least partially raised areas. Patent number: WO/2011/020450 Inventor: R. Prehn Publication date: 24 February 2011
A seal for a potting cavity between two wall components is detailed by patent WO/2011/020601.
the seal can be placed or inserted into a gap (7) between the components as a spatial delimitation, wherein the seal expands as a result of external and/or internal influence (4) and thus generates a contact pressure on the components to seal the gap between the components. Patent number: WO/2011/020601 Inventor: M. Liebner Publication date: 24 February 2011
Spring–elastic axial seal for a gate valve Applicant: Robert Bosch GmbH, Germany This invention relates to a seal (160) for sealing two opposite contact surfaces along a closed contour. It is composed of an elastic sealing element (210) that has two opposite sealing surfaces (240) to bear against the contact surfaces in the region of the contour; two spring elements (220, 230), each of which is associated with one of the sealing surfaces; and a supporting element (250) arranged between the spring elements. It is specifically designed for gate valves. A number of potential geometries are illustrated. Patent number: WO/2011/020643 Inventor: G. Reeb Publication date: 24 February 2011

Sealing Technology
Method for over-moulding a seal on a glass panel Applicant: Saint-Gobain Glass France, France A method has been developed for overmoulding a portion of a seal, on at least one peripheral portion of a glass panel, using a device that comprises a pressing station and two loading/unloading stations. The method of injection, and options for opening and closing the mould, are discussed. The method is particularly applicable to seals for vehicle windows. Patent number: WO/2011/020960 Inventors: G. Huchet and D.-A. Plebani Publication date: 24 February 2011
Gasket and seal for vehicle glazing Applicant: Pilkington Group Ltd, UK This invention relates to vehicle glazing materials provided with clips for retaining glazing components. It also concerns the retaining clips for use with such glazing materials and the trims adapted to fit them. Patent number: WO/2011/021021 Inventor: C. Senge Publication date: 24 February 2011
Seal ring
Seal for a potting cavity between at least two components Applicant: Pfeifer Holding GmbH & Co Kg, Germany This invention relates to a seal (1) for sealing a potting cavity (8) between at least two components (3), in particular wall panels and supports. The design is characterised in that
Applicant: Ford Global Technologies Llc, USA This patent covers a hydraulic rack and pinion steering gear. The design described is intended to provide a wide steering-angle capability within a short steering rack. This is facilitated by a sliding piston housing that enables a relatively long stroke to be achieved without the rack teeth coming into contact with the piston seal. Patent number: WO/2011/020774 Inventors: B. Janz and A. Kogan Publication date: 24 February 2011
An example of the gate-valve seal detailed by patent WO/2011/020643 – using a separate energiser for each of the seal lips.
Applicant: Toyota Jidosha Kabushiki Kaisha, Japan Special seal rings, which are integrally mounted in the cylinder of a screw extruder form the subject of this patent. Lead grooves, extending in the screw shafts, in an axial direction, are formed in outer peripheral surfaces facing the inner peripheral surface of the cylinder, with a predetermined gap between them. The grooves disturb the flow of the object being processed, passing through the clearance gap
