LIQUID SUPPLY DEVICE AND INKJET RECORDING APPARATUS

Abstract: a liquid supply device includes a flow pass, a pump, and an opening/closing device. the pump supplies a liquid to the flow pass. the opening/closing device opens and closes the flow pass. the flow pass includes a plurality of distribution flow passes provided in parallel between the pump and the opening/closing device. each of the distribution flow passes includes a blanch flow pass, a filter, and a check valve. the branch flow pass is branched from the distribution flow pass. the filter filters the liquid flowing in the distribution flow pass. the check valve is provided on a downstream side of the filter. in each of the distribution flow passes, a flow resistance of the filter is larger than a release pressure of the check valve and a flow resistance of the distribution flow pass when the flow pass is opened by the opening/closing device.
