DEFINITION

Classification: 4/385

By varying weight releasable latch:

(under subclass 379) Subject matter wherein the valve is held open by a locking element upon flushing. The locking element is controlled by an element, the weight of which varies in accordance with tank liquid level and which disables the locking element at a predetermined liquid level.

(1) Note. The weight may vary by displacement of the flushing fluid by the element, retention of fluid by the element, or drainage of the fluid from a receptacle type element.
