Abstract (en)

[origin: DE4427799A1] In order to reduce the space occupied by a hydraulic braking system for motor vehicles with brake pressure modulation by means of adjustable vane pumps, all required vane pumps (10, 11, 12, 13) are driven through a common shaft by an electric motor (21) with a stabilised speed of rotation. In order to individually control each vane pump (10, 11, 12, 13), a cam ring (39) is associated to each vane pump (10, 11, 12, 13) and each cam ring (39) is driven by a proportional magnet (16, 17, 18, 19).
