Apparatus for dispensing a liquid material from a reservoir (12), the apparatus comprising a first vessel (11) which forms an intermediate chamber and which is arranged to receive material from the reservoir (12), a second vessel (10) which forms a dispensing chamber and which is arranged to receive material from the intermediate chamber (11), first pressurizing means whereby the intermediate chamber (11) can be pressurized, second pressuring means whereby the dispensing chamber (10) can be pressurized, first valve means (13) operable to permit material to be admitted into the intermediate chamber (11) from the reservoir (12), second valve means (14) operable to permit material to be admitted into the dispensing chamber (10) from the intermediate chamber (11) and a duct (19) extending from within the dispensing chamber (10) whereby material can be dispensed through the duct (19) from the dispensing chamber (10) by pressurization of the dispensing chamber (10)
Apparatus for dispensing a liquid material from a reservoir of said liquid material, said apparatus comprising a liquid material to be dispensed, a first vessel which acts as an intermediate chamber configured to receive said liquid material from said reservoir, a second vessel which acts as a dispensing chamber configured to receive said liquid material from said intermediate chamber, a first pressurizing means, comprising inert gas, for pressurizing said intermediate chamber, a second pressurizing means, comprising inert gas, for pressurizing said dispensing chamber, a first valve configured to permit said liquid material to be admitted into said intermediate chamber from said reservoir, a second valve configured to permit said liquid material to be admitted into said dispensing chamber from said intermediate chamber, and a duct extending from within said dispensing chamber and configured to dispense said liquid material through said duct from said dispensing chamber by pressurization of said dispensing chamber.
Apparatus for dispensing a liquid material from a reservoir of said liquid material, said apparatus comprising an intermediate chamber configured to receive said liquid material from said reservoir, a dispensing chamber configured to receive said liquid material from said intermediate chamber, a first pressurizing means, comprising inert gas, for pressurizing said intermediate chamber, a second pressurizing means, comprising inert gas, for pressurizing said dispensing chamber, a first valve configured to permit said liquid material to be admitted into said intermediate chamber from said reservoir, a second valve configured to permit said liquid material to be admitted into said dispensing chamber from said intermediate chamber, and a duct extending from within said dispensing chamber whereby said liquid material can be dispensed through said duct from said dispensing chamber by pressurization of said dispensing chamber.
