Answer:
Because pressure is on the downstream side of a prv, oil will naturally seep into the spring chamber.
Step-by-step explanation:
- PRV is known as the pressure relief valve that is used in the hydraulic lift systems.
- When the limited system pressure is reached during the lift then this valve responds excess flow to the tank from the system.
- The oil in this prv will automatically gets down into the spring chamber as the pressure is always directed downstream side of prv.
