Abstract
A valve for connecting a second-flow-channel, which supplies a liquid to a liquid-ejecting-head, with a first-flow-channel of the liquid-ejecting-head which ejects the liquid, includes a valve-casing, a first-connector that detachably connects the first-flow-channel, a second-connector that connects the second-flow-channel, a first-connection-port that communicates with the first-flow-channel which is connected with the first-connector, a second-connector that communicates with the second-flow-channel which is connected with the second-connector, and a valve-body in which a connecting-flow-channel is formed for connecting the first-connection-port and the second-connection-port, and that is moved inside the valve-casing to switch a connection state between the first-connection-port and the second-connection-port among a plurality of states. The plurality of states include a first state in which the first-connection-port and the second-connection-port communicate with each other via the connecting-flow-channel, and a second state in which the first-connection-port and the second-connection-port are disconnected.
