Abstract

1372918 Filter-valve assembly BIO-RESEARCH LABORATORIES Ltd 20 June 1972 [29 July 1971] 28807/72 Heading B1D [Also in Division F2] A fluid dispensing valve comprises a valve stem 16 having a recess 34 locating the narrower end of a tapering spring 18, the wider end of which abuts the valve housing so that when the valve is opened the coils of the spring are spaced sufficiently close together that foreign matter particles in the fluid are effectively filtered.
