Abstract: A remote control lever module comprises an inner shaft coaxially located inside an outer shaft. The inner and outer shafts are rotatably mounted on a support and can rotate with respect to one another. A return mechanism is engageable with the inner and outer shafts enabling forward rotation of the inner shaft to cause forward rotation of the outer shaft. The return mechanism further enables extended forward rotation of the inner shaft with respect to the outer shaft, and urges backward rotation of the inner shaft to a rearmost position. The return mechanism limits backward rotation of the inner and outer shafts beyond a nonactuating position. A force spring urges the outer shaft to the nonactuating position. Sensors produce electrical signals proportional to the angular position of the inner and outer shafts. A friction pad can be disposed between the inner shaft and support to frictionally resist rotation of the inner shaft with respect to the support.

Abstract: In an intake manifold, long individual intake pipes (2,2a,2b,2c) lead from a collective intake pipe (1) to the cylinders (3,3a,3b,3c) of an internal combustion engine.

Communication with the transverse pipe (5) is only via the resonance pipes (6,6a,6b,6c). Cutoff devices (7) enable blockage of the connection between the transverse pipe (5) and the individual intake pipes (2,2a,2b,2c) at low engine speeds.
