Abstract

In order to ensure that the valve openings open and close simultaneously the valve member 17 is formed with a plurality of separate orifices 39, 40, 41 which are spaced apart in a direction transverse to the direction of movement of the member, which are arranged simultaneously to define with the control edge 38 of the housing a respective valve opening, and which are connected by respective passages 34, 35, 36 to respective valve chambers 22, 23, 24. <IMAGE>
