Abstract
In a screw volumetric machine, a slide is slidable in a groove along a bore accommodating the screw. This slide is movable to vary the delivery and/or compression ratio. One end of the groove communicates with the low pressure. The other end of the groove communicates with the high pressure. A separation wall separates the two pressures behind the slide. The slide is leak-tightly urged against a free end of the separation wall by holding means which slidingly retain the slide in the groove.
