ABSTRACT:
In a system comprising a gripper (9) and a number of gripping objects (7), and with fluid-communication couplings for establishing temporary fluid communication between the gripper (9) and the gripping object (7) being gripped, the novel feature consists in that the coupling comprise at least one tubular member (30) with at least one open end being adapted to be pressed against and to make fluid-tight contact with a plane surface (37) on the gripping object (7) having fluid-transfer openings (39) with somewhat smaller diameter than the open ends of the tubular member (30). With this arrangement, the risks of damage and other problems associated with previous coupling arrangements based on the male-female principle are avoided.
