Abstract

A transport device (100) comprises a housing (110), an actuator (130) and a drive (150). The housing has a fluid inlet (111, 113) and a fluid outlet (113, 111). The actuator (130) comprises a magnetic shape-memory alloy, and the actuator (130) is arranged at least in sections in the housing (110). The actuator (130) can be deformed by the drive (150) in such a way that at least one cavity (135, 135′) for the fluid is formed in the actuator (130), which cavity can be moved by the drive (150) in order to transport the fluid in the cavity (135, 135′) from the fluid inlet (111, 113) to the fluid outlet (113, 111). At least one section of the actuator (130) has a separation layer (1380) by which a direct contact between the fluid and the actuator (130) is prevented in said section of the actuator (130).
