Abstract
A pump having a main pump body including a casing to which a fluid is supplied, and a pump section, an input valve section, and an output valve section which are provided opposingly to one surface in the casing. Each of the pump section, the input valve section, and the output valve section has an actuator section. The input valve section, the pump section, and the output valve section are provided opposingly to the back surface of the casing for selectively forming a flow passage on the back surface of the casing in accordance with selective displacement action of the input valve section, the pump section, and the output valve section in a direction approaching or separating from the back surface of the casing. The fluid is controlled for its flow in accordance with the selective formation of the flow passage.
