Abstract
A machine with a gland screw for varying the pressure of a fluid, such as a compressor or hand-screw, comprising a gland screw with such high compression ratios could not be rotatably mounted around its axis and meshing with at least one transverse toothed pinion, and a fixed casing applied on at least a part of the external surface of the screw in a sealed manner except for the pinion location, this casing having holes for the intake and the escape of the fluid, characterized in that the number of the teeth of the pinion that are simultaneously engaged with the threads of the screw is at least three for at least one angular position of the screw, the first of these teeth engaging flanks which, on at least a part of their length, are inclined at a certain angle relative to each other. The flanks of the last of these teeth meshed, and because the dimensions and the relative position of the screw of the pinion are chosen so that, for at least one angular position of the screw and for at least one line located in the plane containing the contact lines of the pinion with the screw, the following relationship is satisfied, for at least a part of the portion of the teeth that is in contact with the fillets of the screw in which di is the algebraic distance between the straight line and a point of contact between a flank of a tooth and a fillet, this being measured. Distance from the point along the tangent at this point to the flank of the tooth with the flank in question in opposition to the line in relation to the tooth; is the algebraic distance from this point to the perpendicular lowered from the center of the pinion on the cited tangent, this distance being measured from the point is the absolute value of the distance from the point to the projection of the axis of the screw on the plane of contact between screw and pinion; they are the analogous magnitudes relative to a point of contact between a flank of a tooth and a fillet, this flank being located on the same side as the line in relation to the tooth.
