Abstract

[Problem] To provide a pump device configured so that the discharge of fluid can be limited while the operation of the pump device is stopped. [Solution] A pump device (3) is provided with a casing (10), a movable member (30), a suction valve (41), a discharge valve (42), and a valve mechanism (50). The casing (10) has a pump chamber (100) which can connect to a suction opening (101) and to a discharge opening (102). The movable member (30) can move within the casing (10) and alternately performs the suction of fluid into the pump chamber (100) and the discharge of the fluid from the pump chamber (100). The discharge valve (42) is mounted between the pump chamber (100) and the discharge opening (102) and permits fluid having a pressure higher than or equal to a first pressure to flow from the pump chamber (100) toward the discharge opening (102). The valve mechanism (50) is mounted to the casing (10) and limits the flow of fluid flowing from the suction opening (101) toward the discharge opening (102), the fluid having a pressure lower than or equal to a second pressure which is higher than the first pressure.
