Abstract

A hydraulic start system and methods for operating an engine starter with the same is disclosed. The hydraulic start system may include an accumulator and at least two pumps fluidly coupled with and disposed upstream of the accumulator. The hydraulic start system may also include a first directional valve fluidly coupled with and disposed downstream of the accumulator and upstream of the engine starter. The hydraulic start system may further include a second directional valve fluidly coupled with and disposed downstream of the accumulator and upstream of the engine starter and the first directional valve. The second directional valve may be configured to direct at least a portion of the pressurized hydraulic fluid from the accumulator to the first directional valve to actuate the first directional valve to an open position.
