Abstract:
A switching valve is used in a binary pump. The switching valve is provided with a first liquid delivery port to which a first pump unit is connected, a second liquid delivery port to which a second pump unit is connected, and an output port leading to an output unit that outputs a liquid to be delivered. The switching valve is configured so as to be switched to any one of the following states: a first state in which the first liquid delivery port is connected to the output port and the second liquid delivery port is not connected to any port; a second state in which the second liquid delivery port is connected to the output port and the first liquid delivery port is not connected to any port; and a third state in which both the first liquid delivery port and the second liquid delivery port are connected to the output port.
