Claim 0:
1. A system for maintaining hydraulic pressure at a hydraulic accumulator, the system comprising:
a pressure sensor electrically coupled to a control unit;
a check valve hydraulically coupled to the pressure sensor through a first hydraulic connector; and
a pump hydraulically coupled to the check valve through a second hydraulic connector and electrically coupled to the control unit;
wherein the pressure sensor is configured to mechanically detect a pressure at the first hydraulic connector;
the pressure sensor is further configured to transmit an electrical signal to the control unit when the pressure at the first hydraulic connector falls below a first threshold,
the pressure sensor is further configured to cease transmitting the electrical signal to the control unit when the pressure at the first hydraulic connector exceeds a second threshold,
the control unit is configured to control the pump to urge, at a first time, hydraulic fluid through the check valve into the first hydraulic connector through the second hydraulic connector when the control unit receives the electrical signal, and
wherein the control unit is further configured to control the pump to cease urging hydraulic fluid through the check valve into the first hydraulic connector through the second hydraulic connector when the control unit stops receiving the electrical signal.
