Load-Sensing Pressure compensator for open centre load sensing

P -> T, pX = 0 MPa: Pressure at P pushes the piston against the spring. As of adjusted pressure, the valve opens: P -> T. P -> T, pX > 0 MPa: Pressure at X is added to spring force. The valve opens as soon as opening pressure plus spring pressure is greater than pX.
