Abstract
The present disclosure generally relates to a multi-channel flow control system, more particularly to an oil return control, such as a multi-channel flow control system, that is suitable for hydrostatic rotary mechanisms, and it prevents the oil pump from being damaged due to dry pumping and ensures that the oil storage space does not overflow due to excessive accumulation of hydraulic oil.
