Abstract

A fluidic generator (38) employing a fluidic feedback oscillator (12) in combination with a magnetogenerator (41) is described. Oscillational changes in pressure produced within the feedback oscillator are transmitted to opposite sides of a pole cap (74) which reciprocates a coil (70) in a magnetic field.

Claims

1. A fluidic generator, comprising in combination:

fluidic circuit means for forming a feedback oscillator having first and second output channels;

the oscillator being operable to produce oscillational changes in pressure within the first and second channels;

a permanent magnet connected to the fluidic circuit means and providing a magnetic field;

a wire coil connected in suspended relation to the permanent magnet so as to permit reciprocation of the coil within the field; and

means connected to the coil for reciprocating the coil in response to the oscillational changes in order to induce voltage in the coil.

2. A generator as recited in claim 1 wherein the reciprocating means comprises a flexural member connected to the coil.

3. A generator as recited in claim 1 further comprising:

an outer pole piece connected to the magnet and circumscribing the coil; and

an inner pole piece connected to the magnet and circumscribed by the coil;

the inner pole piece having a bore formed therein;

the bore being a continuation of the first output channel.

4. A generator as recited in claim 3 further comprising a piston slidably disposed within the bore.

5. A generator as recited in claim 3 wherein the fluidic circuit means comprises a header forming a channel which is a continuation of the second output channel;

the continuation of the second output channel being spaced from and aligned in opposed relation to the continuation of the first output channel;

the reciprocating means being disposed between the continuations and operative to reciprocate the coil in response to transmission of the oscillational changes from the continuations to the reciprocating means.

6. A generator as recited in claim 5 further comprising first and second aligned pistons, each being slidably disposed in a respective one of the continuations;

the reciprocating means being operative to reciprocate the coil in response to transmission of the oscillational changes from the pistons directly to the reciprocating means.

7. A generator as recited in claim 6 wherein the reciprocating means comprises a flexural member connected to the coil.

8. A generator as recited in claim 5 wherein the reciprocating means comprises a flexural member connected to the coil.

9. A generator as recited in claim 7 further comprising a second flexural member connected to the coil and spaced from the reciprocating means.

10. A generator as recited in claim 8 further comprising a second flexural member connected to the coil and spaced from the reciprocating means.
