👉 The position fluid, often referred to as the position liquid or simply fluid, is a critical component in hydraulic systems that enables precise control and movement of mechanical parts. It is a viscous fluid that fills the space between moving components, such as pistons and cylinders, ensuring smooth and efficient operation. When pressure is applied to the position fluid, it causes the corresponding mechanical element to move in a controlled manner. This fluid's viscosity and compressibility are key properties that allow it to transmit force effectively while maintaining system stability and responsiveness, making it indispensable in applications ranging from automotive brakes to industrial machinery.
