Reciprocating piston pump for electronically-regulating braking system has stepped piston with its larger diameter section displaced within pump capsule incorporating radial pressure valve

摘要

The pump (1) has a housing (9) provided with a suction valve (11) and a pressure valve (13), enclosing a stepped pump piston (4). The larger diameter section (6) of the piston is displaced within a plastics or sintered metal pump capsule (16) incorporating the pressure valve, positioned radial to the piston displacement.
