An electrically-driven compressor including a housing, an electric motor, a compression mechanism, a cover member, a motor drive circuit, and a sealing member is disclosed. The electric motor is accommodated in the housing. The compression mechanism is accommodated in the housing and operated by the electric motor. The cover member is attached to the housing. The housing and the cover member form an accommodation portion including an accommodation space therein. The motor drive circuit is accommodated in the accommodation space and drives the electric motor. The sealing member is arranged between the housing and the cover member to seal the accommodation space. The sealing member includes an elastic seal portion that comes into close contact with the housing and the cover member. A core sustains the shape of the seal portion in conformance with the circumferential edge of the accommodation space. The core is formed so that at least a circumferential edge part of the core is in conformance with the circumferential edge of the accommodation space. The seal portion is formed integrally with the circumferential edge part of the shape sustaining member by depositing rubber material thereon.

A gasket assembly for sealing between mating flange faces of a flanged connection with a central bore includes a seal member. The seal member is ring shaped and has a seal member profile on an inner diameter. A galvanic anode is a ring shaped member with an outer diameter that is in engagement with the seal member profile, and an inner diameter that is at least as large as a diameter of the central bore.

A spirally wound strip (300) is thicker in the middle and is curved on both sides. Short flats (306) are formed at each side by surfaces that converge towards each other. Soft sealant material (316) extends over the flats (306).

A gasket is provided for creating a seal between two surfaces. The gasket may include a pervious base sheet and a permeating material applied to or incorporated into the base sheet. The gasket is formed by various methods disclosed herein. The gasket may include a base sheet, a primary sealing material covering and/or impregnated the base sheet, and a secondary sealing material covering the primary sealing material. The secondary material may be applied in a predetermined pattern of raised and lowered sections or may be applied as a bead of sealing material. The secondary material may be applied through a variety of techniques including jetting and dispensing using robots such that beads with custom engineered and changing configurations along their lengths are possible. These custom engineered sealing beads provide optimum sealability over the entire area of a joint to be sealed.

The present invention relates to a spring element. The spring element includes a metal ring with a central aperture and radial pleats formed on the metal ring. The radial pleats flatten when pressure is applied axially to compress the ring such that the metal ring increases in effective diameter. The seal element may be used to radially seal an annular bore.

A spiral wound gasket (10) with increased resistance to an inward buckling while sealing flanges at low stress levels, in which an outer guide ring (14) for positioning the gasket within the bolt circle of a bolted flange connection connects to a sealing element (12) having a core (16) that contributes to gasket recovery and made of a spirally wound, chevron-shaped band overlaid by a layer (20) of sealing material covering at least a portion of opposing sides of the core to conformably seal contact faces of flanges to be sealed.
摘要:
A spiral wound gasket made of an elongate band with a portion of the elongate band jacketed by a resilient filler material, the jacketed elongate band wrapped in a plurality of overlapping turns to define a radially thick reinforcing member with the band in each turn enclosed by resilient filler material that abuts contactingly to the resilient filler material in an adjacent turn, the overwrapped portions of the elongate band defining opposing sealingly resilient lateral surfaces, with a leading portion and a trailing portion of the elongate band lacking the jacketing resilient filler material and adjacent turns of the leading portion secured together to fix an inner diameter and adjacent turns of the trailing portion secured together to fix an outer diameter. A method and apparatus is disclosed to wind an elongate band jacketed by a filler material around the perimeter of a die until a desired radially thick spiral wound gasket is formed.
