Abstract: An electrical power generation system includes a hydraulic pump configured to be switchable between operating in a first pump direction and in a second pump direction opposite the first pump direction and a hydraulic motor operably connected to the hydraulic pump to convert hydraulic flow into electrical power. The hydraulic motor has a motor inlet passage and a motor outlet passage. A hydraulic block is located in flow communication with the hydraulic pump and with the hydraulic motor. The hydraulic block is configured such that hydraulic fluid flow exiting the hydraulic block toward the hydraulic motor is directed through the motor inlet passage, regardless of whether the hydraulic pump is operating in the first pump or the second pump direction.
