Fluid distribution system, cleaning apparatus and method

Abstract

A fluid dispensing system (100) comprising: at least one fluid source (110); at least one pump (130-1, 130-2, 130-3, ..., 130-N); at least one telescoping fluid dispenser (140 '‑1', 140'‑2', 140'‑3', ..., 140'‑M'); a control unit (160), which is used to clean at least one target object according to the received ( 150‑1, 150‑2, 150‑3, ..., 150‑O) to operate the pumps (130‑1, 130‑2, 130‑3, ..., 130‑N) to supply fluid (120); manifold (180); and at least one control valve assembly (V-1, V-2, ..., V'-P'), said at least one control valve assembly comprising: The at least one fluid source (110) receives a fluid inlet for discharging fluid to the at least one telescoping fluid distributor (140'-1', 140'-2', 140'-3', .. ., 140'-M'), and a first fluid outlet for allowing fluid to flow from said telescoping fluid dispenser (140'-1 ', 140'-2 when retracting from an extended position to a rest position ', 140'‑3', ..., 140'‑M') back to the second fluid outlet.

Description

technical field [0001] This application claims the benefit of European Patent Application EP18382943.1 filed on December 18, 2018. [0002] The present disclosure relates to fluid dispensing systems, particularly fluid dispensing systems including retractable nozzles that deliver liquid into one or more target objects. The fluid dispensing system of the invention may be applied, for example, to a washing device for washing motor vehicle components, such as optical components, although other applications are not excluded. Background technique [0003] In known fluid dispensing systems, fluid is pumped from a tank or reservoir by a suitable pump and discharged towards a target object through a nozzle connected to the pump. [0004] US5190442 discloses an electronic pump control system for ensuring that the pumps run the same percentage of time. The system includes a container for a liquid, a sensing device for determining the level of the liquid in the container, a plurality...

AI Technical Summary

Problems solved by technology

However, there may be situations where it is still necessary to activate at least one telescoping fluid dispenser while a particular target object has not been completely cleaned

Therefore, there may be residual fluid that becomes trapped in the telescoping fluid dispenser, which undesirably acts as a stop during the rearward movement of the telescoping fluid dispenser

As a result, the fluid dispenser cannot reach its hidden position
