Abstract

PURPOSE:To prevent operation forces, by which an opening and a closed state are respectively produced, from counteracting each other, to reduce the generation of frictional resistance during switching of two states, and to reduce size by producing an opening and a closed state by means of electrostatic attractive force exerted between electrodes and preventing the occurrence of leakage by adhering together two film bodies for holding by means of an electrostatic suction force to hold the two states. CONSTITUTION:A control means to control polarity of a charge fed to an electrode 2 from a power source and a charge feed timing is provided. Opening parts 7 and 8 are formed in moving and stationary film bodies 1 and 3, respectively. An opening state in which the opening parts 7 and 8 are superposed with each other to produce a through-state and a closed state in which the opening parts 7 and 8 are displaced from each other are produced by moving the moving film body 1 toward the stationary film body 3 by means of electrostatic resiliency exerted between the electrodes 2. To hold the opening state and the closed state, leakage between the two film bodies 1 and 3 is prevented from occurring by exerting an electrostatic attractive force between the moving and stationary film bodies 1 and 3 to adhere the two film bodies for holding.

However, in the above configuration, since the pressing force of the spring 52 that presses the plunger 51 against the valve body 50 is always acting, when the valve device is to be opened, it is difficult to open the valve device. Since the plunger 51 is pulled in against the pressing force of the spring 52 and separated from the valve body 50, there is a problem that not only a large amount of current is consumed but also the size of the coil 53 becomes large. Ta. In addition, the plunger 51 is connected to the valve body 50.
In order to prevent air leakage from the gap between the plunger 51 and the valve body 50, the gap is made extremely small to increase the tightness between the plunger 51 and the valve body 50. This has the problem that large frictional resistance acts on the plunger drive, requiring even greater power consumption and coil dimensions.

Regarding the valve device configured as above,
Let's explain its operation. In FIG. 1, air is moving through the moving membrane body 1
The flow passes through a flow path formed by the upper moving opening 7 and the fixed opening 8 on the fixed membrane body 3, but in FIG. 1(A), the moving opening 7 on the moving membrane body 1 and the fixed membrane The fixed opening 8 of the body 3 is in a mutually shifted positional relationship, and the air flow path is in a closed state. At this time, in FIG. 2, positive charges are applied from the power source 5 to the electrodes 4A, 4B, and 4C on the fixed membrane body 3 by the control means 6, and negative charges are applied to the electrodes 2 on the movable membrane body 1. An electrostatic attraction force acts between the fixed membrane body 3 and the movable membrane body 1, thereby holding the fixed membrane body 3 and the movable membrane body 1 in close contact with each other. In addition, in FIG. 1(B), a moving opening 7 on the moving membrane body 1 and a fixed opening 8 on the fixed membrane body 3 are shown.
are in the same positional relationship, and the air flow path is in an open state. At this time as well, the electrodes 4A, 4B on the fixed membrane body 3,
4C is given a positive charge by the power source 5 by the control means 6, and a negative charge is given to the electrode 2 on the moving membrane body 1,
An electrostatic attraction force acts between the fixed membrane body 3 and the movable membrane body 1, so that the fixed membrane body 3 and the movable membrane body 1 are held in close contact with each other. However, electrodes 4A, 4B, 4C and electrode 2
The phase relationship with is not necessarily the same as in the closed state. Figure 1
The movement of the moving membrane body 1 for switching from the closed state of the flow path in (A) to the open state in FIG. Assuming that is the phase state of the electrode in the closed state of the flow path, electrode 2 of the moving membrane body 2 is always given a negative charge, and in the fixed membrane body 3, first, the electrode 4A is given the same negative charge as the electrode 2. is given, and the electrode 2 moves to an intermediate position between the electrodes 4B and 4C due to electrostatic repulsion with the electrode 4A. At this point, a negative charge is applied to the electrode 4B, and the electrode 2 further moves to an intermediate position between the electrode 4C and the electrode 4A. Further, by applying a negative charge to the electrode 4C, the electrode 2 moves to an intermediate position between the electrode 4A and the electrode 4B. This is the same phase state as the beginning, and by repeating the charge application in the above order,
The electrode 2, that is, the moving membrane body 1 moves to the left in the figure. Since the moving membrane body is moved by electrostatic repulsion as described above, the frictional resistance during movement is reduced. In addition, as described above, when the moving membrane body moves to the desired position and the movement is completed, positive charges are given to the electrodes 4A, 4B, and 4C, and the electrode 2 is electrostatically attracted and held in close contact with it. When the moving membrane body is moved, the closed state and the open state of the valve device are selectively applied, and the acting force for bringing the valve device into the closed state and the acting force for bringing it into the open state do not oppose each other. Moreover, the magnitude of the moving force of the moving membrane body and the holding force between the moving membrane body and the fixed membrane body described above is
Since it is given in proportion to the total area of A, 4B, and 4C,
The facing area of the electrodes can be designed to meet the required moving force and holding force.

As described above, the present invention provides a fixed film body having electrodes provided on a thin film of an insulator at predetermined intervals, and a fixed film body having electrodes provided on a thin film of an insulator at predetermined intervals. a movable membrane body having an electrode provided with a movable membrane body, a power source for supplying electric charge to the electrode, and a control means for controlling the polarity of the electric charge and the timing of electric charge supply supplied from the electric power source to the above-mentioned electrode; The membrane body and the movable membrane body are provided with openings, and further have a plurality of fixed membrane bodies and the same number of movable membrane bodies as the fixed membrane bodies, and the fixed membrane bodies and the movable membrane bodies are arranged in an alternating manner. As a result, the movable membrane body moves relative to the fixed membrane body due to the electrostatic repulsive force acting between the electrodes, resulting in an open state in which the openings overlap and pass through, and a closed state in which the openings are shifted. In order to maintain the open state and closed state, an electrostatic attraction force is applied between the fixed membrane body and the movable membrane body to maintain them in close contact with each other to prevent leakage between the two membrane bodies. This is designed to prevent the valve device from selectively switching between a closed state and an open state.
Eliminating the action force for keeping the valve device closed or open and the action force for changing the state from opposing each other, and when moving the moving membrane for switching between the closed state and the open state of the valve device. It is possible to provide a valve device that can reduce frictional resistance and can be made smaller.
