The unit shown in the illustration is beginning the sludge discharge cycle. The operating liquid solenoid valve has been energized and space "J" is filling up. Which of the following actions should occur next? Illustration MO-0112

Correct Answer: Option B — The liquid enters via port "X" into the opening space with the net resultant force causing the piston slide to move down.

Water entering via port "X" fills the opening chamber, creating a net hydraulic force that overcomes the closing pressure in space "J" and forces the piston slide down.
