Abstract

This invention improves the capability of bleeding a chamber, disposed in the course of a line, that receives pressure fluid. On the pressure side of a high-pressure pump that pumps pressure fluid through a line, a chamber of circular-cylindrical cross section is disposed in its course. Two line segments of the line discharge into the upper face end of the chamber. A guide body disposed coaxially with the longitudinal axis of the chamber is received in the chamber in the region of this face end. The guide body embodied substantially in the form of a circular disk, defines an annular gap toward the inside circumference of the chamber and a subchamber of the chamber toward the face end of the chamber. The guide body directs air located in the chamber into the subchamber, from which it is carried away by the flow of pressure fluid. The hydraulic brake system is especially suitable for motor vehicles.
