FILL VALVE REGULATOR AND ASSEMBLY

摘要

A fill valve regulator and assembly for flush systems used in gravity flush toilets allows water to flow into a fill valve at a uniform rate regardless of supply pressure variations. The regulator has an inlet riser which comprises an open bore defined by a riser wall. A guide body is situated within the open bore, the guide body comprising a lower portion having an opening and a shut off seal. A plunger slides within the guide body and a spring that is operable to bias the plunger away from the shut off seal creates an open continuum from the opening in the lower portion through the plunger, the guide body and the inlet riser, the spring being compressible if the spring bias is overcome by a force on the plunger such that the lower portion of the plunger is operable to seal against the shut off seal.

1. A fill valve regulator comprising:
an inlet riser comprising an open bore defined by a riser wall; a guide body situated within the open bore of the inlet riser and fixed to the riser wall, the guide body comprising a lower portion having an opening and a shut off seal; a plunger comprising a lower plunger portion, an upper plunger portion and an open bore, the plunger being slidingly situated within the guide body; and a spring operable to bias the plunger away from the shut off seal such that an open continuum exists from the opening in the lower portion through the plunger, the guide body and the inlet riser, the spring being compressible if the spring bias is overcome by a force on the plunger such that the lower portion of the plunger is operable to seal against the shut off seal.
