    摘要： A pump (10) includes a vibrating plate (11), a flow path forming member (15), a pump chamber (101), and a film valve (13). The vibrating plate (11) is provided with a piezoelectric element (12), vibrates due to distortion of the piezoelectric element (12), and has a gap (114) on an outer periphery. The flow path forming member (15) is disposed so as to face the vibrating plate (11), and has a hole (151) in a portion facing the vibrating plate (11). The pump chamber (101) is surrounded by the vibrating plate (11) and the flow path forming member (15), and has a central space communicating with the hole (151) and an outer edge space communicating with the gap (114). The film valve (13) is disposed in the pump chamber (101). The film valve (13) is in contact with the vibrating plate (11) and the flow path forming member (15) when a pressure in the central space is lower than a pressure in the outer edge space.

    摘要： A liquid path system (12), comprising a flow path selection valve (10), a pump assembly (14), and a fluid network (60). The fluid network (60) comprises a reservoir (64), a first flow channel, a second flow channel, and a reaction device (62). The first flow channel and the second flow channel are each independently in flow communication with the reservoir (64) and the reaction device (62). The pump assembly (14) is in communication with the flow path selection valve (10). The pump assembly (14) is in communication with the fluid network (60). The flow path selection valve (10) is configured to rotate between a first valve position and a second valve position. In the case that the flow path selection valve (10) is at the first valve position, the pump assembly (14) induces the liquid in the reservoir (64) to flow to the reaction device (62) through the first flow channel, and in the case that the flow path selection valve (10) is at the second valve position, the pump assembly (14) induces the liquid in the reservoir (64) to flow to the reaction device (62) through the second flow channel.
