FIELD: engines and pumps. ^ SUBSTANCE: invention is related to propulsion engineering. Gas distributing gear contains valve common for inlet and outlet, inlet and outlet channels, inside of which gate valves are installed, having drive and arranged with superposition of rotation axes onto symmetry axes. Drive of gate valves is arranged with single-sided interrupted rotation, and their front edges are arranged with sharpening. Gate valves are designed for separation of inlet and outlet processes and form three isolated cavities: cavity of inlet channel, cavity of outlet channel and valve pot. Inlet stroke opens simultaneously common valve and inlet channel gate valve (outlet channel gate valve is closed) and air (or fuel mixture) is inlet. Outlet stroke opens the same valve and outlet channel gate valve (inlet channel gate valve is closed), and spent gases are exhausted. Gate valves are turned by step mechanisms and are fixed in closed or opened condition by commands of electronic engine control system. ^ EFFECT: higher reliability of mechanism operation. ^ 2 dwg |
