Hydraulic Systems: Components, Types, and Working …

The hydraulic system working principle is based on Pascal's Law, which states that pressure is transmitted uniformly through a fluid and in all directions. Here's how it functions in practice: When you engage a hydraulic system, the pump generates pressure in the fluid. This pressure flows via the system's pipes and hoses to the actuator.
