Nares seal
PATENTS
Joint boot
Pipe joint with radial flange
Applicant: Toyo Tire & Rubber Co Ltd, Japan This patent describes a joint boot that can be fitted to a non-circular joint body and provide good sealing. This is achieved by molding
arc-shaped inner walls into the inner periphery of the boot in the sealing area. Patent number: WO 2006/043313 Inventor: T. Ohshita Publication Date: 27 April 2006
Nares seal Applicant: Aeiomed Inc, USA This patent describes an apparatus that includes a novel nasal mask which is a nares seal. The system is used for the supply of gas to the
nose of a patient at a positive pressure for the treatment of snoring. Patent Number: WO 2006/044118 Inventors: S.S. Bordewick et al. Publication Date: 27 April 2006
Seal for CV joint boots Cross-section of the adaptable pipe flange joint described in WO 2006/045887.
Applicant: Maricap Oy, Finland This patent describes a pipe joint arrangement, and particularly a type where the pipe itself has a radial flange at the joint. It is designed to overcome problems associated with variations in the shape and contours of the flange, and avoid additional machining. The flange parts are intended to adapt to variations of shape of the collar parts, be suited for use
with different collar shapes, and achieve an easy-to-assemble pipe joint. The flange part of the joint has been arranged to be substantially adaptable against the shoulder of the collar, most suitably its back surface, when the joint is being tightened. Patent number: WO 2006/045887 Inventor: G. Sundholm Publication date: 4 May 2006
Radial piston pump with shaft seal Applicant: Siemens AG, Germany This invention relates to the shaft sealing of radial piston pumps. An intermediate space is provided in the front side of the shaft seal, and a bore hole connects to the return
Applicant: GKN Driveline Deutschland GmbH, Germany This patent describes a seal for the boot of a CV rotary joint. A series of axial fingers from the joint can energize the seal lip to
open the seal during rotation, to allow venting of the joint. Patent number: WO 2006/045362 Inventor: H. Cermak Publication Date: 4 May 2006
Shaft seal Applicant/Inventor: W. Dolzer (Austria) This patent describes a shaft seal that is integral to a bearing. It is intended for the output shaft of an expansion turbine used in a refrigerator or a heat pump, particularly those designed to work on CO2. The plastic seal ring (13) is pressed
into contact with the opposing radial face by the internal pressure of the refrigerant gas. The seal is manufactured from PTFE or PVDF material, and is claimed to be effective even when the internal pressure is 100 bar. Patent number: WO 2006/045610 Publication date: 4 May 2006
line. The purpose is to prevent the seal being subjected to negative pressure during engine starting. Patent number: WO 2006/042765 Inventors: U. Nigrin and N.-T. Vu Publication Date: 27 April 2006
Seal assembly Applicant: Wahler Metalurgica Ltda, Brazil This patent refers to a new arrangement for the rotor set of the water flow control valve used in automotive cooling or air conditioning systems. The main novelty here is an arrangement of
springs which are assembled in the O-ring carrier to provide mechanical robustness and assure elastic characteristics under all operating conditions. Patent number: WO 2006/045172 Inventor: J.J. Cardinali Ieda Publication Date: 4 May 2006
Cylinder head seal Applicant: ElringKlinger AG, Germany This invention relates to a multilayer metal cylinder head gasket that includes a pressure sensor. A seal is built into the gasket, and 16
the sensor measures the pressure acting on the seal. Patent number: WO 2006/045351 Inventor: U. Maier Publication Date: 4 May 2006
The bearing in a CO2 refrigerant system expansion turbine that incorporates a radial sealing ring, from WO 2006/045610.
