Abstract
The present invention provides a dispensing system comprising a self-gassing liquid to be dispensed and a dispenser for dispensing the self-gassing liquid, the dispenser including: a valve housing having an inlet for receiving the liquid and an outlet through which the liquid is to be dispensed; a valve chamber and/or passage extending between the inlet and the outlet, and a valve arranged to open and close the valve chamber and/or passage; pressure maintaining means arranged to maintain the pressure of liquid at the inlet to the valve housing at a constant pressure during successive dispensing operations; and control means for controlling the opening and closing of the valve, the control means being arranged to open and close the valve to commence and terminate each successive dispensing operation, wherein the period for which the valve is open determines the quantity of liquid dispensed. The dispensing system may permit very small quantities of liquid to be dispensed with great accuracy and avoid the liquid being subjected to high shear forces. The system is particularly beneficial for the dispensing of peracetic acid.
