<p>The switching arrangement is intended for the carburettor of a combustion engine containing manually or automatically controlled fuel enrichment device (3, 7, 6, 1) for use during starting. Additional fuel is admitted via a starter valve (7) and a control valve (6). The valve (6) is operated by a diaphragm (5) which moves under the action of the vacuum in the air intake (13) and of an adjustable (9) bimetallic spring (2), so that additional fuel supply (1) to the intake is reduced at increasing engine speed and/or temp. The valve (6) may be solenoid-controlled from an engine speed sensor.</p> |
