Hydraulic Closed-Center Circuit with Load Sensing

Load sensing is achieved with a special compensator mounted on a variable displacement pressure-compensated pump. The reader should envision this special compensator mounted on the pump shown in Fig. 4.15. For this analysis, we assume that the special compensator is set to destroke the pump at 200 psi. (The pump develops 200 psi and is …

Hydraulic Closed-Center Circuit

The closed-center circuit shown in Fig. 4.18 has a variable displacement pump like that shown in Fig. 4.15. The compensator valve spring is a 2500 psi spring. The pump builds 2500 psi before the compensator valve moves to open a pathway for fluid to flow to the yoke actuating piston. The piston extends and forces …
