Rotor pump e.g. vacuum pump, for use in motor vehicle, has adjustable lubricant feed rate- limiter provided in supply line and comprising orifice plate, and mandrel insertable into opening of orifice plate

摘要

The pump has a pump housing (12), and a rotor that is rotatably supported in the housing. An adjustable lubricant feed rate -limiter (36) is provided in the supply line. The limiter is provided with an orifice plate (44) and a mandrel (50), which extends in a flow direction (40) of lubricant. A blade has blade spikes lying at an inner peripheral surface of a work space. The mandrel is insertable into an opening of the orifice plate. An independent claim is also included for a lubricant feed rate-limiting device for a rotor pump.
