DEVICE FOR GAS SUPPLY TO INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: device has carburetor-mixer with diffuser and throttle gates, gas reducer-evaporator with high and low pressure spaces, pressure regulator, batcher with batching and controlling spaces and needle, and valve provided with a chamber separated into two spaces by a diaphragm. One of the spaces of the valve is in communication with a space inside the carburetor-mixer downstream of the throttle through the nozzles and with atmosphere through an additional nozzle. The cut-off member of the valve is secured to the diaphragm and interacts with an opening made in the batcher housing. The second space of the valve is in communication with a space of low-pressure of the reducer-evaporator through a pipe line and the second additional nozzle. At starting of the engine, the needle cuts off the gas flow into the batching space of the batcher, and required portion of gas flows to the carburetor-mixer through the second additional nozzle independently of speed of rotation of the engine shaft. EFFECT: improved design. 1 dwg
