Question

in a hydraulic accumulator brake system, the
______ directs pump oil flow to the brake
accumulator charging valve or to another
hydraulic system.

1. relief valve

1. orifice

1. priority valve

1. charging valves

Explanation:

To solve this, we analyze each option:

• Relief valve: Primarily relieves excess pressure, not direct flow to accumulator or other systems.
• Orifice: Controls flow rate/limits flow, not for directing flow to specific components.
• Priority valve: Directs pump oil flow to the brake accumulator charging valve or another hydraulic system, matching the description.
• Charging valves: Involved in charging the accumulator, not directing pump flow to it or other systems.

Answer:

1. Priority valve
