Abstract: A hydraulic actuator system includes a load sense assembly that is configured to transmit a load sense signal to a variable pump to vary a flow of pressurized fluid from the variable pump in response to the load sense signal to generate a desired flow to the actuator. The load sense assembly includes a load sense boost valve (LSBV) configured to dynamically boost the load-sense signal according to the desired margin pressure and the flow demand from the system. When flow demands are low, margin pressure will be above the set threshold of the adjustable LSBV, and no boosting occurs. When flow demands are high and pressure in the load sense line drops to the set threshold, or minimum margin pressure, the LSBV begins boosting the load sense signal pressure dynamically. The boosted load sense signal signals the variable pump to stroke and displace more fluid to increase flow to the actuator.
