Abstract
A positive-displacement machine for compressible media has a positive displacement body that is retained on a disk-like rotor, which is eccentrically drivable relative to the housing, in such a manner that each of its points executes a circular motion during operation. To that end, an eccentric disk is disposed on a drive shaft, and the rotor is supported on this disk by means of an oil-lubricated bearing. The lubricating oil is delivered and removed to and from the side remote from the drive side of the drive shaft, and the separation of the oil inflow from the oil return flow is effected in the housing by a slide bearing which has one oil chamber each on both ends. The separation of the oil streams is effected by an indentation that does not extend over the entire length of the slide bearing. Through this indentation, the slide bearing is likewise supplied with oil. The indentation connects the oil inflow bore in the housing with the oil chamber.
