The powerful FPC3 power steering pump supplies exactly the right amount of oil that is needed for operating hydraulic steering systems in passenger cars and light commercial vehicles.
Function
Powerhouse with integrated pressure limiting
The FPC3 power steering pump is powered via a motor belt drive. The hub or belt pulley is pressed onto the shaft. Mounting the pump to the engine bracket is done either directly or via a pump bracket.
The FPC3 consists of a housing with a pressed-in intake port and an integrated volume flow control, valve screw with a pressure connection thread, cover, front plate, shaft and rotor set. The rotor set is comprised of a rotor, ten radially-guided blades as well as the cam ring with two symmetrically arranged suction and pressure zones. The fixed geometric delivery volume is defined by the design of the cam ring. The pump shaft is installed in the housing with a ball bearing and in the cover with a needle bearing.
The volume flow control limits the supplied volume flow to a fixed value and a pressure control valve in the valve pistons controls the system pressure.
