Abstract: Prior art washer designs have segmented radial ducts feeding the filter valve which collect the filtrate emerging from the longitudinal ducts. Because these ducts are radial, the volume at the periphery is much greater than at the valve entry which creates undesirable conditions such as a large volume where air can escape from the filtrate forming a pocket which will reduce the effectiveness of the vacuum and promote non-uniformity in filtrate velocity. The present invention incorporates a baffle in the radial duct which reduces the volume at the periphery and maintains a uniform cross-sectional area for the filtrate to reach the valve. This maintains a constant filtrate velocity and prevents the possibility of the formation of an air pocket.
