Hydraulics & Pneumatics Test Questions

Q.  What is the function of unloading relief valve and can it be used as an accessory for accumulators?

a. unloading relief valve is used to charge the accumulator by a pump when accumulator pressure falls below the set value and it can be used as an access
b. unloading relief valve is used to charge the accumulator by a pump when accumulator pressure falls below the set value but is not used as an accessory
c. unloading relief valve is used to charge the accumulator by a pump when accumulator pressure rises above the set value but is not used as an accessory
d. unloading relief valve is used to charge the accumulator by a pump when accumulator pressure rises above the set value and is used as an accessory
