Hydraulic start systems and methods for the same

A hydraulic start system for an engine starter, comprising:

• at least two pumps configured to receive hydraulic fluid and pressurize the hydraulic fluid, wherein the at least two pumps comprise an air driven pump and a hand driven pump;
• an accumulator fluidly coupled with and disposed downstream from the at least two pumps, the accumulator being configured to receive and store the pressurized hydraulic fluid from the at least two pumps;
• a pilot operated check valve fluidly coupled with and disposed downstream of the accumulator and upstream of the engine starter, the pilot operated check valve configured to control a flow of the pressurized hydraulic fluid from the accumulator to the engine starter;
• a directional valve fluidly coupled with and disposed downstream of the accumulator and upstream of the engine starter and the pilot operated check valve, wherein the directional valve is configured to direct a first portion of the pressurized hydraulic fluid from the accumulator to the pilot operated check valve to actuate the pilot operated check valve to an open position, and wherein the directional valve is further configured to direct a second portion of the pressurized hydraulic fluid from the accumulator to the engine starter;
• and
• a flow control valve disposed downstream of the pilot operated check valve, the flow control valve configured to restrict a flow of the pressurized hydraulic fluid from the pilot operated check valve to the engine starter.
