ABSTRACT:
The present invention is a control unit which controls the supply of compressed air to a plurality of inflatable devices for inflating them and for venting air from them in order to deflate them. The unit has valves which are operated by finger operable devices. The valves are arranged in two groups. The first group of valves are disposed between an inlet connected to the source of compressed air and a corresponding number of individual ports which are connected to the inflatable devices. The second group of valves are connected between a venting outlet and the ports or a corresponding number of further ports which are connected to the inflatable devices.
