Hydraulic radial piston pump for vehicle braking system - uses pair of packing rings to act as pressure and suction valves

摘要

Hydraulic radial piston pump in which at least one of the two valves (12,14) is formed by a packing ring. The ring which seals the valve body against the surrounding walls is made as a pressure valve (14). The ring which seals the piston (3) against the cylinder walls (2) acts as a suction valve. The valve seat (7) is formed fast with the housing (1). USE/ADVANTAGE - Hydraulic radial piston pump for vehicle braking system is of simplified construction with reduced costs and also lowers noise emission.
