    摘要： The invention relates to a double seat valve, which is capable of cleaning the seat and which is improved compared to that of the prior art, whereby a delivery as free from turbulence as possible of the seat cleaning flow into and out of the leakage cavity is ensured, and a pressure-increasing direct action upon the seat areas is reliably prevented. This is achieved in that: the second closing element (4), when in its closed position, rests with a stopping surface (4e), which is placed on a face of its cylindrical projection (4*), upon the interface (2e; 2e*) and, to be precise, directly upon the first seating (2a, 2g) in an adjoining manner; in the face of the second cylindrical projection (4*), a central recess (4d) is provided which, radially outside, starts (starting point of contour (K)) with a rotationally symmetric reversing surface (4b) and is delimited on the face by a face (4c) oriented, in essence, essentially perpendicular to the longitudinal axis of the second closing element (4), the reversing surface (4b) leading into the face (4c) (leading point of contour (K)); the reversing surface (4b) and the stopping surface (4e) form a second wraparound edge (U2) that, when the second closing element (4) is closed, directly abuts against a first end section (2g) of the first seating (2a); when viewing the meridian section, the reversing surface (4b) has a contour (K) with a bend-free curve, a direction vector in the leading point of the reversing surface (4b) points into a discharge borehole (3d) centrally provided in the first closing element (3) without colliding with the first closing element (3) in the vicinity of its areas bordering the leakage cavity (5) or of the middle seal (8; 8*) and forming dynamic pressure, and; a front-side delimitation of the first closing element (3) facing the leakage cavity (5) is at an axial safe distance (x) from the direction vector on an outlet point of the interface (2e) into the first end section (2g), said outlet point being formed as a first wraparound edge (U1).

This is achieved in that: the second closing element (4), when in its closed position, rests with a stopping surface (4f), which is placed on a face of its cylindrical projection (4*) and which, together with the peripheral wall (4c, 4h), forms a second wraparound edge (U2), upon the interface (2e, 2e*), and to be precise, directly upon the first seating (2a) in an adjoining manner; the peripheral wall (4c), at its end facing away from the first closing element (3), merges into a rotationally symmetric reversing surface (4d) (starting point of contour K)), and this reversing surface (4d) leads in a face (4e) of the recess (4b) oriented, in essence, perpendicular to the longitudinal axis of the second closing element (4) (leading point of contour K)), and; when viewing the meridian section, the reversing surface (4b) has a contour (K) with a bend-free curve, a direction vector in the leading point of the reversing surface (4d) points into a discharge borehole (3d, 3d*) centrally provided in the first closing element (3) without colliding with the first closing element (3) in the vicinity of its areas bordering the leakage cavity (5) and forming dynamic pressure.

    摘要： In a throttle valve controlling apparatus (200), there is provided a pair of first and second throttle valves (2;4). The first throttle valve (2) is rotated by an electrically controlled actuator means (13), whereas the second throttle valve (4) is rotated by an accelerator pedal (9). A first return spring (16) is provided on the first throttle valve (2) so as to return this valve (2) to a first closed position when the electrically controlled actuator means (13) is brought into malfunction, by which an engine speed is rapidly reduced. Under this malfunction condition, the second throttle valve (4) can be independently controlled by the accelerator pedal (9).

    摘要： Un dispositif d'accouplement rapide est destine a des conduites de fluide sous pression. Ledit dispositif d'accouplement comprend un corps (1) et un raccord (2), tous les deux etant pourvus d'un canal d'ecoulement. Le raccord (2) est concu pour etre introduit dans le canal d'ecoulement du corps (1) en partie pour ouvrir une soupape de fermeture armee avec un ressort (20, 21, 22) et par consequent ouvrir un passage d'ecoulement au travers du dispositif d'accouplement. En outre, le raccord (2) est concu pour maintenir ladite soupape (20, 21, 22) et ledit passage d'ecoulement ouverts et les deux parties principales (1, 2) du dispositif d'accouplement connectees l'une a l'autre, a cette fin ledit raccord est engage de maniere liberale dans un dispositif de verrouillage a bille ou autre dispositif de verrouillage a bille ou autre dispositif de verrouillage semblable dans le corps (1). La soupape de fermeture dans le canal d'ecoulement a l'interieur du corps (1) comprend deux pieces de soupape cooperant entre elles (21, 22) qui, sous l'influence du raccord (2), sont deplacees axialement dans ledit canal a la fois l'une par rapport a l'autre et par rapport au canal. Le trait le plus caracteristique du dispositif d'accouplement rapide de l'invention est qu'une piece (22) de la soupape de fermeture est disposee a l'interieur d'au moins un organe en forme de boitier (23) qui peut etre deplace le long d'un segment de la paroi du canal d'ecoulement dans le corps de maniere a fonctionner comme une soupape a tiroir par rapport aux ouvertures d'ecoulement (19; 24, 26, 27) dans ladite paroi debouchant et partant dudit segment de canal, les ouvertures (19) debouchant sur ledit segment etant inclues dans le canal d'ecoulement au travers du dispositif d'accouplement rapide et les ouvertures (24, 26, 27) provenant dudit segment communiquant avec les environs immediats du dispositif d'accouplement rapide pour l'evacuation de pression de l'interieur (45) du canal d'ecoulement dans le corps lorsque le raccord (2) en est retire alors

    摘要： The present invention relates to a non-return valve that can be configured for use anywhere along a molding material flow path in a molding system. The non-return valve of the present invention includes an improved means to restrict the backflow of melt therethrough during injection. In particular, a spigot-seal is configurable, during injection, between overlapping, closely-spaced, and mutually parallel complementary male and female spigot portions that are configured between complementary valve members. The spigot-seal advantageously maintains an effective backflow restriction even in the eventuality of transient movement between the spigot portions during injection. Preferably, the non-return valve of the present invention is also configured to include a means for mutually aligning and/or guiding the complementary valve components that ensures a proper alignment between the complementary spigot portions, and may also serve to improve the function and longevity of a face-seal, when present. The non-return valve of the present invention provides particularly advantageous utility when configured for use in a barrel assembly of an injection unit for the injection molding of a metal alloy.

    摘要： A controllable valve (10), preferably an electromagnetically controlled valve, has two valve stages of which the first (14, 18) is actuated and the second (16, 20) works automatically. The open cross-section of the first valve stage (14, 18) is small and the open cross-section of the second valve stage (16, 20) is large. The first valve stage (14, 18) keeps the second valve stage (16, 20) closed. When the first valve stage (14, 18) is opened, a spring element (32) opens the second valve stage (16, 20). This valve (10) may be advantageously actuated by a small actuating force that is exclusively available to the first valve stage (14, 18). It also has a large open cross-section and thus a small flow resistance.
