摘要： In the vertical die casting device of this invention, the molten metal is poured from the gate into the sleeve with the cavity gate closed by the counter tip; and when filling the cavity with the molten metal, the plunger tip and the counter tip are lowered at the same speed so as not to pressurize the molten metal held between the tips to prevent the temperature reduction of molten metal so that when the counter tip opens the cavity gate with the plunger tip continuing to move down the molten metal can smoothly flow into the cavity.

摘要： In axial plunger pump of the type wherein a swash plate is rotated while a cylinder body is kept stationary, plungers are axially slidably inserted into respective cylinder bores in the cylinder body, and the rotating swash plate cooperates with the plungers to obtain an axial stroke movement thereof for a pump operation. A stopper member is provided for cooperation with the plungers so that the stroke movement of the plunger in a direction toward the swash plate is limited. An actuator is provided for controlling an axial position of the stopper plate for obtaining desired variations of the effective stroke of the plungers.

摘要： An electromagnetically driven valve includes a driven valve having a stem and carrying out reciprocating motion along a direction in which the stem extends, a disc support base having an abutment surface, a disc extending from one end coupled to the stem toward the other end supported by the disc support base so as to allow free oscillation of the disc, and an electromagnet applying electromagnetic force to the disc. The disc has a root portion formed at the other end, and an arm portion formed from the root portion to one end. The electromagnet has a surface facing the arm portion. When the disc is attracted to the electromagnet the abutment surface abuts on the root portion and a gap is created between the surface and the arm portion. With such a structure, excellent quietness and durability can be achieved and energy loss can be reduced.

摘要： A method of casting including the steps of closing gates with a counter tip after lower and upper molds heated to a predetermined temperature have been clamped, pouring melt into a sleeve in which a plunger tip is lifted a predetermined distance, lowering the plunger tip while displacing the counter tip to a predetermined position to open the gates, which are formed such that the ratio of the volume of products to the cross-sectional area of the gates is 20-40 (i.e. the volume of products/(CM.sup.3) cross-sectional area of gates (CM.sup.2)=20-40), to allow the melt to flow into cavities via the gates by the force of gravity alone with the plunger tip reaching the upper surface of the melt the moment a percentage of the melt placed in the cavities has reached a value between 30 and 70%, and pressure-filling the cavities with the melt by the plunger tip with the melt passing through the gates at 0.4-0.8 m/sec.
