Vehicle brake assembly piston pump, has pistons that lie diametrically opposite to each other, and leaf-spring unit provided with drive such that drive transfers compressive force to each piston and is movable in moving direction of piston

摘要

The pump (28) has two pistons (18) that lie diametrically opposite to each other. A u-shaped leaf-spring unit (30) is provided with an eccentric drive (14) in such a manner that the drive transfers a compressive force to each piston and is movable in a moving direction of the piston. A circular recess is arranged in a cross section. The pistons are coupled at the eccentric drive with each of its front side in a compressive force transmitting manner.
