Abstract (en)
[origin: US4375747A] A control system is disclosed for use with pressure-driven loads, such as reversible motors. The system allows the loads to be driven at varying speeds and also allows the loads to be reversed. However, the system is so designed that an operator cannot subject the loads to pressure shock caused by abrupt changes in pressure by adjusting the system too rapidly. The system disclosed is suitable for use with either hydraulic or pneumatic loads.
