Patent number: 5362201Abstract: A motor vehicle water pump lubricating chamber arrangement having a housing in which a pump shaft is rotatably journalled which carries a running wheel at a free end thereof and which in a lower region adjoining the running wheel has at least one seal. In a region above the lower seal between the pump shaft and the housing there is provided a chamber filled with lubricating medium so that any fluid lubricant which can otherwise discharge around the shaft will have such fluid caught in the lubricating medium chamber rather than escaping with any trace and track of escaping fluid along any external surface of the water pump which could mislead someone to prematurely replacing the water pump when such replacement is not yet necessary. The pump shaft is journalled free of play via roller bearings including roller bodies pressed into the raceways provided on the pump shaft and on the housing respectively.Type: GrantFiled: July 12, 1993Date of Patent: November 8, 1994Assignee: Kaco GmbH & Co.Inventors: Klaus-Jurgen Uhrner, Eugen Schlotzer

Patent number: 4278218Abstract: A seal, especially for dishwashers, for sealing a shaft. The seal comprises a bellows made of elastic material, with a support housing and a slide ring associated therewith. The bellows at least partially overlaps the slide ring and the support housing. An inner side of the outer wall of the bellows engages an axially parallel peripheral wall of the support housing. The seal also comprises a pressure spring which operates between the support housing and the slide ring. The peripheral wall of the support housing, and the inner side of the outer wall of the bellows, have such a profiling that support surfaces are arranged on the peripheral wall transverse to the force of the pressure spring, and that corresponding countersurfaces are arranged on the outer wall, the support surfaces and countersurfaces being arranged in axial sequence.Type: GrantFiled: May 29, 1980Date of Patent: July 14, 1981Assignee: KACO GmbH & Co.Inventor: Klaus-Jurgen Uhrner

Patent number: 4136885Abstract: An axial shaft sealing unit for sealing a stationary machine part relative to a rotatable machine part. The sealing unit includes a slide ring seal mounted on the stationary machine part in a sealing manner and includes a housing with a bottom located transversely to the axis of the slide ring seal, a primary seal forming a sliding ring, a bellows-like secondary seal, and a compression spring arranged between the primary seal and the housing bottom or base. The bellows-like secondary seal is vulcanized in a position which corresponds substantially to its installed position and is held in this position in its operative state by a detachable holder. A counter ring rests directly against a machine component which is non-rotatably connected to the rotatable machine part.Type: GrantFiled: January 25, 1978Date of Patent: January 30, 1979Assignee: Kupfer-Asbest-Co.

Patent number: 4124219Abstract: A slide ring seal structure for sealing machine elements rotatable about an axis, especially for sealing pump shafts, with an about rotation-symmetric housing which at one end face has a bottom extending transverse to the axis of the seal structure. The slide ring seal structure also has a primary seal designed as slide ring located in the interior chamber of the housing, and further has a bellows-shaped annular secondary seal as well as a spring arranged between the slide ring and the bottom of the housing. The secondary seal has an outer cone which flares in the direction of the sliding surface of the slide ring and has associated therewith a corresponding inner cone of a clamping member coaxially surrounding the secondary seal. The axial position of the clamping member relative to the slide ring and to the secondary seal being determined solely by the axial force exerted upon the clamping member during the installation of the slide ring seal structure.Type: GrantFiled: November 17, 1977Date of Patent: November 7, 1978Assignee: Kupfer-Asbest-Co.
