A wind power installation is provided having a pylon, a pod mounted rotatably on the pylon, a generator arranged within the pod and having a rotor and a stator, and at least one fan in the region of the pod. In order to reduce the entry of moisture, sand and other foreign substances into the pod and also to reduce the fan noise which reaches the exterior, the fan may suck in outside air through a downwardly open first air gap, in particular between the pylon and the pod. The fan may be adapted to blow air out of a rear part of the pod, through an air gap between the stator and the rotor and into a front part of the pod. A seal structure may be positioned in the pod in such a way that an air flow that bypasses the air gap between the stator and the rotor is substantially prevented.

The invention claimed is: 1. A wind power installation comprising:a pylon;a pod mounted rotatably on the pylon, the pod having a front interior portion and a rear interior portion;a generator arranged within the pod between the front interior portion and the rear interior portion, the generator including a rotor and a stator and having an air gap between the rotor and the stator;at least one fan in the region of the pod, the fan being arranged to draw outside air into the rear interior portion of the pod through a downwardly open first air gap positioned between the pylon and the pod and force the outside air through the air gap between the rotor and the stator into a front interior portion of the pod;a pod fairing surrounding at least a portion of the rear interior portion of the pod, the pod fairing configured to guide the outside air toward the air gap between the rotor and the stator; andseal structures positioned in the pod to substantially prevent air flow from bypassing the air gap between the rotor and the stator when the outside air is forced from the rear interior portion to the front interior portion.
