Gravity controlled automatic fluid dosing system - uses pivoting reservoir to operate inlet valve and control outlet jet for fluid distribution

摘要

A reservoir (1) has fitted to it an inlet jet assembly (4r-7r) and an outlet jet (4v-7v). The outlet jet is open to the atmosphere while the inlet jet is fitted to a flexible pipe whose remote end is connected to a pressure reducer (37). The reservoir is mounted on a beam (15) with a hub assembly (19) allowing it to pivot. A counterbalance (18) is fitted to the remote end in an adjustable position. This counterbalance keeps a supply valve (33) open to allow water to flow through a filter (36) and pressure reducer to the inlet jet. This allows the reservoir to fill when the counterbalance rises to turn off the water supply. A ball (5v) in the outlet jet slides in its cavity to allow the reservoir to empty when a similar action in the inlet jet allows air into the reservoir. A flexible pipe on the outlet jet permits usage of the water. ADVANTAGE - Operates on low supply pressure.
