摘要： A piezoelectric valve whose housing defines a valve chamber wherein at least one piezoelectric flexural transducer is located. The piezoelectric flexural transducer possesses a contact face, which faces a first outer wall of the valve housing. This first outer wall is in the form of a wiring support which possesses a support body consisting of plastic material, which at the outer side opposite to the valve chamber bears a wiring arrangement. The wiring arrangement is in electrical contact by way of a via extending through a cutout in the support body with the piezoelectric flexural transducer, since the via consists of an electrically conductive elastic plug, against which the at least one contact face is thrust at the inner face of the support body.

摘要： A piezoelectric bending transducer includes a support body, a stack of piezo-ceramic layers, arranged thereon and flat electrodes arranged between the layers. On the side of the support body facing the stack, an adaptation layer is arranged with essentially the same coefficient of expansion as the piezo-ceramic. The bending transducer displays a good actuating power and a low thermal natural distortion with economical production costs. The transducer is particularly suitable for application in a valve.

摘要： A valve means which comprises a control chamber in a valve housing and into which several fluid duct open. In the control chamber there is at least one pivoting control rocker member serving for the control of at least one of the fluid duct openings and able to be moved between two terminal positions, one pivotal position of such control rocker member being influenced by an electrically activated flexible element. The flexible element may act within the control chamber on an actuating part of the control rocker member. The latter is biased by spring means into a first terminal position, the flexible element engaging the actuating portion of the control rocker member in the electrically non-excited state mechanically free of stress and without any spring bias.

摘要： A method for the manufacture of a valve having at least one valve opening surrounded by at least one valve seat and an elongated valve member able to be brought into different positions by pivoting. In order to adjust the switching stroke of the valve member the valve member is, for instance using a laser, locally and briefly heated until superficial plastification occurs so that in the direction of the pivoting movement performed in operation it experiences a permanent flexural deformation.

摘要： A flexural actuator is fitted with an actuator means, the flexural actuator being fitted at its functional section with a sensor means for determination of the longitudinal stretch. This sensor means is placed at a position, and/or is placed in the longitudinal direction symmetrically on either side of such position, at which there is a constant longitudinal stretch independent from the setting force when the functional section is thrusting against a resistance.

摘要： A piezo valve having a flexural transducer unit which includes two flexural transducers adapted to be deflected in opposite directions. The flexural transducers are fixedly joined together at one terminal part of the flexural transducer unit with the formation of a common bearing section. The flexural transducer unit is pivotally mounted in relation to the housing. At least one flexural transducer serves for the control of a valve opening associated with it, the other flexural transducer being able to be biased by the application of a drive voltage toward a support face arranged in a deflection path in order to for instance to increase the displacement path of the other flexural transducer.

摘要： A micro-valve arrangement whose micro-valve has a housing containing two opposite housing layers, between which a valve chamber is delimited, wherein a valve member is located. A fluid duct extending in one housing layer opens into the valve chamber and is controlled by the valve member. By means of an electrically operated actuator it is possible for the position of the valve member to be predetermined. Furthermore a position detector is present, which on the basis of the measured capacitance of a capacitor renders it possible to find the position of the valve member. This capacitor comprises two capacitor faces which are provided opposite to each other in the direction of motion of the valve member and on one of the housing layers.
