Abstract: Rings for a rolling bearing are disclosed, wherein the rings define a primary axis (A). The ring may include a ring formed as a hollow ring having a hollow chamber encircling the primary axis (A). A wall of the hollow ring may be of one-piece and/or seamless design in an axial section along the primary axis (A). The ring may be a bearing ring configured for rolling contact with rolling elements. In one example, the wall includes a raceway section in the wall for rolling contact with the rolling elements, a bearing bottom section for supporting the ring, two lateral supporting wall sections, and two connecting sections for connecting the two lateral supporting wall sections to the raceway section.

Abstract: A metering pump for varnish or laquer includes a housing in which are arranged a first gear wheel and a second gear wheel which is in engagement with the first gear wheel. At least the first gear wheel is mounted with a shaft in the housing. The pump further has a sealing device provided for the first gear wheel, wherein each gear wheel has a conveying area formed by a toothing, and wherein the sealing device is arranged between the conveying area and an end face area of the gear wheel. The sealing device is sealed in the housing by a radial sealing device.

Abstract: A paint conduit has a jacket surrounding an interior and a hose arranged in the interior of the jacket. At least one end member is attached to a first end of the jacket and secures a first end of the hose in the jacket. The at least one end member has an end member section inserted between the jacket and the hose. The first end of the hose is at least as long as the jacket within the at least one end member. The hose extends through the at least one end member and an insert is inserted into the first end of the hose and presses the hose radially against the at least one end member.

Abstract: A varnishing installation includes a varnish line with an inlet end, an outlet end and an auxiliary device. The auxiliary device is connected through a valve arrangement to the varnishing line and the valve arrangement is scrapeable.

Abstract: A paint conduit has a conduit wall enclosing an interior and a cleaning device that has a hose arranged in the interior and a pressurized fluid source connected to the hose. The hose is expandable at least in a radial direction of the hose and is inflated by the pressurized fluid source to displace the paint, present in the paint conduit, from the paint conduit when new paint is to be conveyed through the paint conduit.

Abstract: The paint-spraying apparatus exhibits a supply line 7 for coating material, extending from the color changer to the atomizer. Cut-off valves 26, 27 installed in the supply line delimit an insulating section 25 of said supply line, which insulating section is associated with means 28 to 32 for emptying and flushing said insulating section 25. A voltage divider 16 is connected in parallel to said insulating section 25. When colors are changed, the residual coating material present in said voltage divider 16 can be moved into the empty insulating section 25, after which it is forced by means of slugs back through the entire supply line 7 to the color changer 1, and is thus reclaimed.

Abstract: A valve for a branching and/or connecting location of a piggable line for coating material such as paint includes a valve housing for a first throughgoing line, to which at least one second line is selectively connectable, as well as a valve closure body that is spring loaded by a valve spring and that is movable against the force of the valve spring. The valve housing and the valve closure body respectively have flushly aligned bores that have the same contour and the same diameter as each other, and that are directly adjoining each other in the closed position. This diameter is equal to the clear inner diameter of the piggable line. For opening and closing the second line, the valve closure body is movable in the valve housing in the axial direction of the bore thereof.

Abstract: An electrostatic paint atomizer connected to a discharge station at high voltage is supplied, via an isolating conveying line, with individual divided-off quantities of paint enclosed between two pigs from a loading station at the other end of the conveying line. The paint is conveyed by a transport device supplying a thrust medium (compressed air or insulating liquid) to discharge the paint in the discharge station. A reverse transport device operating with compressed air transports the pigs back to the loading station. The length (L) of the conveying line between the loading and the discharge stations and the length (l) of a divided-off quantity of paint, are dimensioned to provide a sufficiently long isolating path (L-l) to avoid a voltage flashover. A continuous supply of paint is achieved with two parallel conveying lines, through which quantities of paint are metered with an offset from each other.
