Upon removal of the teat cups from these outlets, a cover of the washer unit automatically descends from a washing position with a rotating movement to cover the outlets; and to prepare for the next washing operation, the cover is lifted and rotated to its washing position, where it is held by the teat cups when re-applied to the outlets.,下面是Milking unit washer专利的具体信息内容。

1. A washer unit for teat cups which comprises a manifold having an inlet for a cleaning liquid and having outlets adapted for application of respective teat cups to provide for flow of the cleaning liquid through the teat cups, a cover having a closing position for covering said outlets and movable to an open position to allow said application of the teat cups to said outlets, and means operatively connecting the cover to the manifold for automatically effecting return of the cover from said open position to said closing position in response to removal of the teat cups from the manifold outlets.
2. The washer unit of claim 1, in which said means include a post extending upwardly from the manifold for guiding the cover while it is raised to its open position, the cover being rotatable in one direction relative to the manifold to move the cover to said raised open position, said means also including a member operable to rotate the cover in the opposite direction during downward movement thereof to said closed position.
3. The washer unit of claim 2, in which the cover and post have substantially concentric coacting surfaces, said member being a detent on one of said surfaces, the other surface having a vertical groove receiving said detent and configurated to effect said rotational movement in said opposite direction.
4. The washer unit of claim 1, in which the cover has a vertical axis and elements radiating from said axis for covering the respective outlets in said closing position of the cover, the cover forming gaps between said elements, said means including a post on which the cover is movable to said open position by raising the cover while rotating it in one direction about said axis, thereby aligning said gaps vertically with the respective outlets to permit said application of the teat cups, said means also including a member operable to hold the cover in said raised open position upon engagement of a said element with a teat cup applied to one of said outlets and located in one of said gaps, said member being operable to permit downward movement of the cover by gravity while rotating the cover in the opposite direction in response to removal of the teat cups from said gaps, whereby the cover returns automatically to said closed position.
