Since the shape of the injection jet is necessarily influenced by changes in the shape of the orifice in devices using this principle, such devices do not function well except in fully open and fully closed positions. With respect to the opening in the intermediate state, the injection jet may scatter or change, which has a significant negative effect on the molding quality. Accordingly, there is a recognized need and utility for a well-functioning outlet mechanism or variable flow control device.

る。 The same problems in metal casting are found in the non-metal-based glass or other material manufacturing industry, which involves molten materials and molding processes. An improved outlet mechanism is proposed in which the cross-sectional area of the orifice is varied by depositing a thicker or thinner layer of hardened material on the walls of the outlet channel by adjusting the temperature of the outlet channel. It was done. An example of such a device is the device described in Luxembourg patent no. 82177, which must be equipped with an electric heating device as well as a cooling device. Such devices have a fairly long response time when regulating flow and require periodic monitoring of thermal balance to maintain the desired flow jet. Furthermore,
At small aperture sizes, the jet shape becomes irregular due to sediment disturbances in the channel walls.

To achieve this objective, the device of the invention is provided with two cylinders whose axes are arranged parallel to each other. The cylinders are rotated about their respective axes and brought into line contact at a common line. At least one cylinder is provided with a partially circumferential groove. The other cylinder can also have a smooth circumferential surface. The groove is provided over a portion of the circumferential surface of the cylinder in a direction substantially orthogonal to the axis, and has a contour whose depth varies from zero to maximum. Preferably, both cylinders are provided with grooves of the same shape. Machining in the body of at least one cylinder, but preferably in the bodies of both cylinders, identically shaped grooves of suitable contours, the two cylinders being superimposed so that the apertures described by the contours of the grooves are symmetrical. By positioning the cylinders so that the cylinders have the same shape, the opening cross section changes when the cylinders are rotated in opposite directions, but the initial cross-sectional shape is always maintained (i.e., the cross-sectional shape does not change).

性を維持するにはコストがかかる。 In a preferred embodiment of the invention, the groove of each cylinder is constructed with a pseudo-elliptical profile. This configuration produces an orifice that is always circular in cross section and symmetrical about the line of line contact between the cylinders. However, simpler contours are also possible. However, it is costly to maintain continuity and uniformity of the jet while changing the orifice cross-sectional shape and the opening amount of the outlet.

For this purpose, the two cylinders are provided with a gear or pinion device and a drive mechanism, which may also be a simple lever. Or, in more advanced applications, a servo motor can be provided that acts on one of the two cylinders. Furthermore, the device of the present invention is provided with pressing means for pressing the two cylinders against each other to bring them into line contact. This means can be, for example, a pressure screw. Furthermore, auxiliary sealing means between the two cylinders may be provided, for example by superimposing one cylinder on the other.

る。 The flow control device according to the present invention has two cylinders A and B, and a quasi-elliptical groove 10 is provided on the circumferential surface of each cylinder in a direction perpendicular to the axis of the cylinder (see FIG. 1). That is, each groove 10 has a shape resembling an oval notch, saddle, or depression that extends circumferentially along a portion of the circumferential surface of the cylinder. In cylinders A and B, corresponding points on the circumferential edges of the grooves 10 of each cylinder are in line contact with each other on the line between the cylinder axes, so that the cross section of the groove intersection area is always circular, and the diameter of this circle is the diameter of the cylinder. varies based on the degree of rotation. Since the cylinder is used as an outlet mechanism, the orifice is formed by the groove 10, and the outlet is always circular, but the diameter of the circle changes when the groove parts come into contact. Due to these variations in the contours of the grooves 10 along the circumferential surface of the cylinder, the openings described by the overlapping groove contours change as the cylinder rotates in the direction indicated by the arrow. In this way, in the state shown in FIG. 1A, the depth of the groove becomes maximum at the line contact position between cylinders A and B, so that the maximum opening 01 is obtained. To create a smaller or smaller aperture, cylinders A and B are rotated in opposite directions, cylinder A clockwise and cylinder B counterclockwise, to create aperture 02. If this movement continues, the opening 03 will become smaller than that shown in Figure 1C, and eventually the cylinders will come into contact with each other in the grooveless part of the cylinders, and this outlet will be completely blocked as shown in Figure 1D. It becomes closed state. 1st
In Figure A-1D, the arrow indicates the direction of flow of the molten material through the outlet, which has a circular cross section when viewed from inside the container containing the molten material.

The outlet groove shown in FIG. 2 has a simple outline because the bottom surface has a linear shape as shown in FIGS. 2A, 2B, and 2C. However, as is clear from FIG. 2A, in this embodiment the aperture has a circular shape only in the positions where the bottom surfaces of the grooves are parallel to each other, and in other positions, for example in the position of FIG. 2B, the aperture has an elliptical profile. becomes. Similar to that shown in Figures 1A-1C, the arrows in Figures 2A, 2B and 2C indicate the direction of flow of the material to be cast or formed.

acts as a support for the two cylinders A and B. The bearing block 3 is attached to the outer surface of the molten material container by means of attachment elements or mechanisms 1 and 2. The two cylinders A and B are synchronously rotated in opposite directions by a gear or pinion 5 on the drive shaft of each cylinder. The rotation mechanism (not shown) can be a lever, screw, or servo motor. A load-generating or pressure mechanism 4, which may be constituted, for example, by a pressure screw, brings the cylinders into intimate pressure contact with each other, so as to seal the cylinders except when and where the grooves 10 engage.
