Abstract
The invention relates to a valve comprising a housing and a closing member arranged in the housing, from which member a shaft protrudes via which the closing member is rotatable in the housing. In order to provide a working and easy-to-use valve, the closing member comprises a sector closing the opening, a flexible sector having a thinner wall than the closing sector, a guiding sector having the same radius (R) as the inner surface of the housing wall, and an open sector.
Claims10
A valve, comprising
- a housing whose wall has an inner surface curving around an axis of rotation and which joins together a first part and a second part of a flow channel, of which at least the first part or the second part is connected to the housing via an opening in the wall of the housing,
- a closing member arranged in the housing and a shaft protruding from the closing member by which the closing member is rotatable in the housing around said axis of rotation between a position covering the opening and a position uncovering the opening, said closing member including
- a sector closing the opening,
- a guiding cylindrical sector in contact with the housing wall to position the closing member relative to the housing,
- a flexible sector having a wall thinner than a wall of the closing sector and a wall of the guiding cylindrical sector, the guiding cylindrical sector being joined to the closing sector via the flexible sector only, and
- an open sector that is a void extending from a bottom of the closing member to completely separate the closing sector from the guiding cylindrical sector.
