PCT No. PCT/SE96/01763 Sec. 371 Date Oct. 1, 1998 Sec. 102(e) Date Oct. 1, 1998 PCT Filed Dec. 30, 1996 PCT Pub. No. WO97/24517 PCT Pub. Date Jul. 10, 1997An intake system for internal combustion engine comprises a separate intake manifold for each engine cylinder with a first manifold portion extending between the intake valves of the respective cylinder and a first air distribution chamber, and a second manifold portion forming a connection between the first air distribution chamber and a second air distribution chamber. For each cylinder there is arranged a valve which in a first position connects the intake manifold portions and in a second position opens these intake manifold portions towards the first air distribution chamber, in such a way that the valves are simultaneously acutuatable between these two positions by means of control means with regard to the motor speed. The following is an examiner's statement of reasons for allowance: The prior art fails to teach or fairly suggest the claimed invention as a whole including a first manifold portion extending between the intake valve(s) of the respective cylinder and a first air distribution chamber, and a second manifold portion forming a connection between the first air distribution chamber and a second air distribution chamber, said first air distribution chamber having a valve arranged for each cylinder, said valve having a first position which connects the intake manifold portions and a second position which opens these intake manifold portions towards the first air distribution chamber, in such a way that the valves are simultaneously actuatable between these two positions by means of control means with regard to the motor speed, characterized in that for each cylinder there is arranged a valve body designed as a connector pipe, which is rotatable about an axle and which in the first position forms a tight connection between the two manifold portions and in a second position is located outside the ends of the manifold portions, so that these are exposed. |
