<p>A valve (41) comprises an inlet (43), a first outlet (49) and a second outlet (55). A first valve member (57) of the valve (41) cooperates with a valve seat (59) of the first outlet (49), and a second valve member (61) of the valve (41) cooperates with a valve seat (63) of the second outlet (55). The first and second valve members (57, 61) are provided on a common driving shaft (67) which is displaceable by an electric actuator (69) to regulate an air flow through the first outlet (49) and an air flow through the second outlet (55). The first and second valve members (57, 61) are combined into a single integrated valve member (65) which cooperates with both the valve seat (59) of the first outlet (49) and the valve seat (63) of the second outlet (55). A simple and compact structure of the valve (41) is obtained in this manner. The valve (41) is used in an air-assisted fuel-injection system (3) of an internal-combustion engine (1), wherein the first outlet (49) of the valve (41) is connected to a bypass (51) of a throttle valve (29) of the engine (1) and the second outlet (55) of the valve (41) is connected to an air-assisted fuel injector (31) of the fuel-injection system (3). In this manner, both the atomization of the fuel injected by the fuel injector (31) and the idling speed of the engine (1) are controlled by a single valve (41).</p> |
