The present disclosure discloses a reducing noise double-channel oil pump including a pump body. The pump body connects an oil box and an actuator. Parallel distributed a small and a big flow oil channels are located between the oil box and the actuator. The small flow oil channel connects a first twin pump and first one-way valves. The big flow oil channel connects a second twin pump and second one-way valves. The pump body also disposes a reducing noise oil channel. A connection of the reducing noise oil channel and the big flow oil channel locates a one-way controlled valve. Another end of the reducing noise oil channel connects an oil pressure feedback oil way. A connection of the reducing noise oil channel and the oil pressure feedback oil way locates an oil pressure driving mechanism. The middle of the reducing noise oil channel connects an unloading oil way.
