FIELD: engines and pumps. ^ SUBSTANCE: electrically operated valve for fluid medium to control the fluid medium flow in fluid medium channel in fuel feed station, for example in carburettor or low pressure spray system, of internal combustion engine; at that, fluid medium valve includes the following: plunger movable along the axis and containing constant magnet having its magnetic direction oriented along the axis, thus creating the front pole and rear pole; chamber passing along the axis and having two opposite valve seats restricting the plunger movement along the axis; at that, front valve seat faces the front pole, and rear valve seat faces rear pole; electromagnetic drive unit to retain the plunger along the axis between two stable positions of the valve when voltage is supplied. When in closed and open positions, the plunger magnet and ferromagnetic element of the corresponding valve seat are located at some distance from each other in order to avoid direct contact to each other. Group of inventions also includes fuel feed station, for example carburettor or low pressure spray system, of internal combustion engine, throttle gate position sensor to determine the position of throttle valve and rod of the gate in fuel feed station, for example carburettor or low pressure fuel spray system, of internal combustion engine, control module for fuel feed station, for example carburettor or low pressure fuel spray system, of internal combustion engine, and ignition system of internal combustion engine. ^ EFFECT: invention allows creating fuel feed station with low fuel consumption and low exit gas emissions. ^ 56 cl, 12 dwg |
