Abstract

The invention relates to a transport device (100) comprising a housing (110), an actuator (130), a drive (150) and a sealing element (170). The housing has a fluid inlet (111, 113), a fluid outlet (113, 111), and partially contains the actuator (130), which comprises a magnetic shape-memory alloy. The actuator (130) can be deformed by the drive (150) in such a way to form a cavity (135) for the fluid in order to transport the fluid in the cavity (135) from the fluid inlet (111, 113) to the fluid outlet (113, 111). The sealing element (170) is arranged between the actuator (130) and the housing (110) in such a way that the cavity (135) is edge-sealed or end-sealed during the transport of the fluid from the fluid inlet (111, 113) to the fluid outlet (113, 111).
