Abstract
An exhaust valve comprises a body, a shaft rotating relative to the body along a first axis of symmetry, a gate secured to the shaft, a ball joint hinging the shaft relative to the body, and an interface comprising a power take-off. The power take-off has a misalignment relative to the first axis of symmetry.
Claims8
An exhaust valve, comprising:
- a hollow tubular body having a first passage section;
- a shaft passing through the hollow tubular body and engaged on each side in a respective bearing secured to the hollow tubular body in order to allow a rotation of the shaft, relative to the hollow tubular body, along a first axis of symmetry of the shaft;
- a gate secured to the shaft and positioned in the hollow tubular body, the gate having a second section substantially identical to the first section;
- a ball joint hinging the shaft relative to the hollow tubular body;
- and
- an interface organ secured to the shaft to transmit, to said shaft, any rotational torque about the first axis of symmetry and at least a force along the first axis of symmetry, the interface organ comprising a power take-off able to receive said torque and/or force, wherein the power take-off has a misalignment relative to the first axis of symmetry to create a lever arm able to transform a force applied to the interface organ along the first axis of symmetry into a torque about a second axis perpendicular to the first axis of symmetry.

An exhaust line comprising:
- an exhaust valve positioned in the exhaust line, the exhaust valve comprising
- a hollow tubular body having a first passage section,
- a shaft passing through the hollow tubular body and engaged on each side in a respective bearing secured to the hollow tubular body in order to allow a rotation of the shaft, relative to the hollow tubular body, along a first axis of symmetry of the shaft,
- a gate secured to the shaft and positioned in the hollow tubular body, the gate having a second section substantially identical to the first section,
- ball joint hinging the shaft relative to the hollow tubular body, and
- an interface organ, secured to the shaft to transmit, to said shaft, any rotational torque about the first axis of symmetry and at least a force along the first axis of symmetry, the interface organ comprising a power take-off able to receive said torque and/or force, wherein the power take-off has a misalignment relative to the first axis of symmetry to create a lever arm able to transform a force applied to the interface organ along the first axis of symmetry into a torque about a second axis perpendicular to the first axis.
