COMPULSORY RETURNING APPARATUS FOR SECONDARY-SIDE THROTTLE VALVE

PURPOSE:To permit the perfect linkage of throttle valves by certainly preventing the delay action of a secondary-side throttle valve free from the influence of a residual supercharged pressure, in the apparatus in which a supercharger is installed into a suction passage and a primary-side and a seco...

Zusammenfassung:	PURPOSE:To permit the perfect linkage of throttle valves by certainly preventing the delay action of a secondary-side throttle valve free from the influence of a residual supercharged pressure, in the apparatus in which a supercharger is installed into a suction passage and a primary-side and a secondary-side throttle valves are installed on the downstream side of the supercharger. CONSTITUTION:When a primary-side throttle valve 3 is opened by stepping-in an acceleratig pedal 2, the pressure in a suction passage 19 on the downstream of a supercharger increases, the when the pressure in a chamber 17 increases through a pressure conduit 18 over the force of a spring 14, a diaphragm 16 shifts to turn a secondary-side throttle valve 6 clockwise through interlocking means 13, 1, 8, and 9. When the accelerating pedal 2 is returned in deceleration, the primary-side throttle valve 3 is closed, and at a same time, a connecting lever 9 is turned counterclockwise through a roller 10 by the turn of a kick lever 5 clockwise, and therefore, the secondary-side throttle valve 6 turns counterclockwise. Since a follower lever 11 freely moves with the secondary-side valve shaft 7 at this time, the influence of the residual supercharged pressure in the chamber 17 is suppressed.
