Product Overview

This extract provides detailed information about the operation of the brake pump unit. Each cartridge in the system features a rotating inner member known as the rotor, which contains vanes that maintain contact with a fixed interior cam surface. As the drive shaft rotates the rotor, the vanes extend outwards, creating a cavity that allows fluid to flow into the inlet ports.

Key Features

• Rotating Inner Rotor: The rotor contains vanes that extend due to centrifugal force and contact the cam surface.
• Cam Surface Design: A fixed cam surface ensures continuous pumping as the rotor vanes expand and contract the cavity.
• Pressure-Actuated Vanes: Vanes are pushed against the cam ring by centrifugally activated pins for efficient fluid transport.
• Feed Holes Mechanism: Feed holes provide consistent pressure under the vanes by opening to the pressure port every revolution.

Benefits

• Efficient Fluid Movement: The system efficiently moves fluid from inlet to outlet, maintaining system pressure reliably.
• Smooth Operation: Centrifugal force and pressure-actuated mechanisms offer seamless functionality.
• Durable Design: Pressure-actuated components ensure long-term reliability and reduced maintenance needs.

Usage Recommendations

• Ensure the drive shaft rotation is consistent to maintain optimal vane operation.
• Regularly inspect the pressure and pins for wear to maintain the efficiency of the brake pump.
• Use compatible hydraulic fluid to prevent damage to the internal surfaces and maintain proper function.
