DEVICE FOR WETTING A PLURALITY OF THREADS, AND METERING PUMP FOR SUCH A DEVICE
First Claim
1. A device for wetting multiple threads with a fluid, the device comprising:
- multiple wetting means assigned to the threads; and
a dosing pump which is connected to the wetting means by multiple conveying lines, wherein the dosing pump has multiple conveying means for generating multiple dosing flows of the fluid and has multiple pump outlets, to which the delivery lines are connected, wherein the conveying means are formed by at least one planetary gear set arranged between housing plates, wherein multiple planet gears of the planetary gear set are guided freely by a centering plate between adjacent housing plates, wherein the planet gears of the planetary gear set have in each case one passage opening, and wherein the passage openings of the planet gears are connected by a channel system to at least one pump inlet.

Abstract
Particular techniques involve a device for wetting multiple threads with a fluid, and a dosing pump which is connected to the wetting means by multiple conveying lines. The dosing pump has multiple conveying means for generating multiple dosing flows of the fluid and has multiple pump outlets, to which the delivery lines are connected. The conveying means are formed by at least one planetary gear set arranged between housing plates. To achieve, as far as possible, a uniform throughflow without a significant dead space volume, multiple planet gears of the planetary gear set are guided freely by a centering plate between adjacent housing plates. The planet gears of the planetary gear set have in each case one passage opening, which are connected by a channel system to a central pump inlet. It is thus possible to realize close fits and flushing of gaps.
