Flush valve handle assembly providing dual mode operation

摘要

A dual mode flush valve includes a handle assembly having a handle, a bushing and a plunger. The bushing has a sleeve with a passage therethrough for mounting the plunger for sliding and tilting. The passage is defined by first and second partially overlapping bores that coincide at the inner end of the sleeve and are spaced one above the other at the outer end of the sleeve. The bores define a horizontal plunger travel axis and an angled plunger travel axis. Depending on which direction the user actuates the handle the plunger will travel along one of these axes. Travel along the angled axis will lower the plunger tip, allowing earlier clearance of a relief valve and a reduced flow through the flush valve compared to actuation with the plunger travel along the horizontal axis.

主权项

1. A handle assembly for a dual mode flush valve, the handle assembly comprising:
a handle having a handle face plate for engaging a plunger; the plunger having a face plate and a shank having an end for engaging a valve stem; a bushing with a passage therethrough having a first opening larger than a second opening; the plunger shank being slidably and tiltably disposed within the bushing passage; and the bushing passage defining a solid waste plunger travel axis and a liquid waste plunger travel axis, the solid waste plunger travel axis and the liquid waste plunger travel axis being non-parallel.
