Abstract
A coupling guard for a rotor, which includes a housing for enclosing the rotor in an inner space of the housing, the housing extending longitudinally along a length of the rotor; a ventilation system for creating a flow of gas in the inner space from a gas inlet to a gas outlet that exhausts outside. The gas inlet includes a pipe extending along a pipe longitudinal axis from outside to inside the housing. The pipe includes a first opening located outside the housing and a second opening located inside the housing in the inner space. The pipe has the second opening close to the rotor when the housing encloses the latter. The second opening has a curved edge wherein a projection of the curved edge onto a plane extending parallel to the longitudinal axis of the pipe and parallel to the axis of longitudinal extension is a segment of curve.
