A selector valve for connecting at least one inlet or outlet line to any one of a number of fluid ports. The valve includes a plurality of closely adjacent valve elements (31-33) provided with through-passing openings which can be caused to communicate with one another in a predetermined fashion, by moving the valve elements relative to one another. The valve elements are arranged in a series from the one outer element (31) having a lowest order number to the other outer element having a highest order number. Each of the movable valve elements can be moved actively through a given distance, backwards and forwards in at least one given direction relative to the valve element having the next higher order number. Each valve element of a higher order number dogs passively each of the nearest adjacent, movable valve elements of lower order number. These valve elements therewith retain those relative positions taken in relation to one another and in relation to the valve element of higher order number. |
