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

Transport device having an actuator and separating layer

A transport device () comprises a housing (), an actuator (), a drive () and a sealing element (). The housing has a fluid inlet () and a fluid outlet (). The actuator () comprises a magnetic shape-memory alloy, and the actuator () is arranged at least in sections in the housing (). The actuator () can be deformed by the drive () in such a way that two cavities (') for the fluid are formed in the actuator (), which cavities can be moved by the drive () in order to transport the fluid in the cavities (′) from the fluid inlet () to the fluid outlet (). The sealing element () has at least one recess (, . . . ), and the sealing element () is arranged in the housing () in such a way that the cavities (′) are at least temporally in fluid communication via the recess (, . . . ) during the transport of the fluid from the fluid inlet () to the fluid outlet ().

Conveying device containing shape memory alloy

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