• a housing, and an oil port provided in the housing;
• a dosing pump arranged in the housing such that the housing defines an integral operational cover component of the dosing pump;
• a yarn guiding device configured on the housing with an oil transfer element embedded therein such that the moving yarn moves through the oil transfer element within the yarn guiding device;
• the oil transfer element connected to the oil port by an oil feed channel via the dosing pump;
• a closure element and a flow sensor provided in the oil feed channel;
• the oil feed channel defined by the housing and comprising a first portion from the oil port to the dosing pump, a second portion from the dosing pump to the closure element, and a third portion from the closure element to the oil transfer element;
• wherein the flow sensor is provided in the second portion of the oil feed channel;
• and
• the dosing pump is controlled by the controller to deliver a metered flow of oil to the oil transfer element based on yarn type and yarn speed without excess oil leakage from the yarn guiding device.
