ABSTRACT:
Flowable material is pumped between upstream and downstream passages in a body through an aperture portion formed in a side member that communicates between the passages. An annular seal member engages the slide member under the urging of a Belleville spring. The slide member, formed as a filter, has a region of uniform porosity that is moved progressively through the path of flow of the material for changing the filter.
