A protective device (22) consists of a path valve (24) controlling the pressure medium connection from the pressure side of the pump (52) to the storage tank (14). At least one operating device (26) activates the path valve and consists of an expansion material component converting the temperature of the pressure medium in the storage tank into a positioning movement.
