SU432614A1 - NON-CONTACT MAGNETOPNEUMATIC NON-SWITCHING DEVICE - Google Patents

Description

one

The invention relates to the field of automatic and remote control mechanisms.

Non-contact magneto-pneumatic switching devices are known, comprising a housing with chambers, connected throttling channels, nozzles and ferromagnetic plates.

These devices do not provide the possibility of simultaneously issuing signals on two different output channels.

The proposed device is made with three nlastinami, one of which is fixedly mounted near the nozzles, and the other two are located at an angle to the first, fixed console and serve as damper flaps. This allows different combinations of signals to be obtained at the outputs of the device.

Pa figs. 1 shows a sketch of a contactless magneto-pneumatic switching device; in fig. 2 is a sketch of the arrangement of ferromagnetic plates.

The switch body 1 is made of a non-magnetic material. It has four chambers 2-5, two of which (2 and 3) are input, and two (4 and 5) are output. The input chambers have a common branched supply channel 6. Each of the output chambers has nozzles 7 and 8 and channels 9 and 10 of the output signal. The input chambers are connected to the corresponding output chambers by throttling channels I and 12. In the housing there are three ferromagnetic plates 13, 14 and 15, one of which (13) is fixedly fixed near nozzles 7 and 8, and the other two (14 and 15) are fixed console under angle to the first so that they can overlap with the fixed plate 13, thus blocking the nozzles 7 and 8. The output of both nozzles 7 and 8 is connected with the atmosphere by the channel 16.

Pa figs. Figure 1 shows the static state of the device.

The device operates when exposed to an element that has an external constant

magnetic field (e.g. permanent magnet, current coil). Power is supplied to input 6, nozzles 7 and 8 are open and there are no signals at outputs 9 and 10.

The peculiarity of the operation of the proposed switching device is the selectivity of Illa or the simultaneous operation of the movable plates 14 and 15, depending on the location of the acting element.

When exposed to an external device

by the magnetic field on the side of the plates 13 and 14, the main part of the magnetic flux is closed through them. The plates are magnetized and the movable plate 14 is attracted to the stationary 13, closing the nozzle 8 at the same time. At the exit 10, a signal appears, the part of the flow entering the plate 15 is non-opaque and practically does not magnetize it. When a driver acts on the device from the side of the plates 13 and 15, the main part of the magnetic flux closes through them, the movable plate 15, attracting the stationary 13, closes the nozzle 7. A signal appears at the output 9. In this case, the plate 14 does not magnetize.

If the acting element is above the plates, and the direction of the spline of the field created by it is parallel to the movable plates 14 and 15, then the magnetic flux is closed through all three plates. Both movable plastids 14 and 15 are attracted to unconnected 13, while closing both nozzles 7 and 8, and signals appear at both outputs 9 and 10.

Thus, the device allows the output of the following signal combinations: OO, 1-0, 1-1, 0-1.
