Electrohydraulic set, especially for vehicle hydraulic braking equipment, has device for switching between different hydraulic active surfaces

摘要

An electrohydraulic set has a piston pump (2) in which at least one piston (11) of the pump (2) is segmented and a device for switching over between different hydraulic active surfaces or combinations thereof (A1,A1+A2) is provided. The switching device comprises a blocking latch (23) engaging tightly with the piston (11) or the piston segment (19,20) and the blocking latch (23) is movable transversely, especially at right-angles or obliquely, to a piston movement direction.
