PROCEDURE AND APPARATUS FOR THE CONVERSION OF SMALL, CONTINUOUS AND PRESSURIZED FLOW IN ELEVATED FLOW IN PULSES.

摘要

THE INVENTION REFERS TO A METHOD AND TO A DEVICE FOR CONVERTING A LOW AND CONTINUOUS FLOW IN A HIGH, INTERMITTING AND PULSING FLOW AND IS ESPECIALLY ADAPTED TO OPERATE ASPERSORS, SHOWERS, ETC TO A LOW FLOW LEVEL. THE FLUID IS INTRODUCED IN THE FORM OF A CONTROLLED FLOW OF LOW POWER, AS FOR EXAMPLE THROUGH THE USE OF A DROP (5, 24) IN A SUPPLY PIPE (7) INSIDE A CONTAINER (1, 22) THAT HAS AN EXPANDABLE CHAMBER. THE EXTERNAL FLOW OF LIQUID FROM THE CHAMBER (2) IS RESTRICTED UNTIL THE PRESSURE CREATED BY THE INTRODUCTION OF THE LIQUID IS SUFFICIENT TO OVERCOME THE ACTION OF THE VALVE AND MAKE IT OPEN, AND IN RESPONSE TO THE RESISTANCE OF THE FLOW, THE FLUID IS PROJECTED INTERMITTENTLY TO A GREATER FLOW. THIS IS ACHIEVED BY USING A PRESSURE SENSITIVE VALVE (8, 28), DESIGNED TO PERFORM A QUICK RESPONSE, TO CREATE A WATER HAMMER EFFECT. THE INVENTION DESCRIBES PULSE VALVES AND OTHER DEVICES THAT OPERATE IN RESPONSE TO THE DEFORMATION CREATED IN ELASTIC MEMBRANES IN RESPONSE TO PRESSURE CHANGES.
