The invention provides an oil supply throttling device for cold running of an engine and starting before release of a starter, which comprises a shell provided with a chute and a pressure cavity which are separated from each other, an oil supply path for circulation of lubricating oil is arranged in the chute, and the pressure cavity is provided with an air inlet connected with starter bleed air and an air outlet connected with balance bleed air; the valve comprises a gate valve, a partition plate and a connecting rod for connecting the gate valve and the partition plate; the spring is arranged in the pressure cavity and located between the partition plate and the shell. When an engine is in cold running or a starter is started before being disengaged, the starter introduces air into the pressure cavity from the air inlet, the partition plate overcomes the pressure of the spring and balances the air introduction pressure to enable the gate valve to slide downwards in the sliding groove, then the pipe diameter
