Abstract
A device comprising a cylindrical sliding gate (3), transversely arranged relative to the air conduit(s) (2) in a bore (4) arranged in a cylinder head (1) movable between a first position closing (P2) the conduit (2) and a second position opening (P1) the conduit (2) by the action of an actuating arrangement (16, 14; 17; 18, 19).
Claims5
A device for controlling opening and closing of at least one internal combustion engine cylinder head air intake conduit, said device comprising:
- a cylindrical sliding gate transversally arranged relative to at least one air conduit in a bore arranged in the cylinder head;
- the gate slidably movable in the bore between a first position closing the conduit and a second position opening said conduit;
- actuating means for slidably moving the gate between the first and second positions;
- for each conduit, said cylindrical sliding gate successively comprising on its length a first part creating a generally cruciform platform and a second part that is comprised of a vertical partition whose length is approximately equal to a diameter of a conduit, each of said first and second parts being delimited by two disks perpendicular to a longitudinal axis of the sliding gate.
A device for controlling opening and closing of at least one internal combustion engine cylinder head air intake conduit, said device comprising;
- a cylindrical sliding gate transversally arranged relative to at least one air conduit in a bore arranged in the cylinder head;
- the gate slidably movable in the bore between a first position closing the conduit and a second position opening said conduit;
- actuating means for slidably moving the gate between the first and second positions;
- for each conduit, said sliding gate successively comprising on its length a first part creating a generally cruciform platform, and a second part that is comprised of a cylindrical rod with a hole whose longitudinal axis of symmetry is perpendicular to the longitudinal axis of the sliding gate and whose diameter is equal to the diameter of a corresponding air intake conduit.
