Abstract
The invention provides a pressure noise suppression system which includes a fluid input circuit 22 for receiving pressure pulses carried by a first fluid which is displaceable; a fluid vessel 10 having a non-linear tube 28 containing a second fluid; a signal generator 18 for transmitting pressure pulses carried by the first fluid for displacing the second fluid; a fluid output circuit 36 having a displaceable third fluid; and a pressure sensor 38 for sensing pressure impulses which pass through the second fluid.
Claims10
A pressure noise suppression system, comprising:
- a) fluid input means for receiving pressure impulses carried by a first fluid which is displaceable;
- b) fluid container means connected to said fluid input means, said fluid container means including a non-linear tube;
- c) a non-compressible and displaceable second fluid in said non-linear tube;
- d) means for transmitting said pressure impulses carried by said first fluid through said second fluid and for displacing said second fluid in said non-linear tube, said second fluid blocking the transmission of noise-type pressure impulses having a time period different from the time period of said second fluid;
- e) fluid output means connected to said fluid container means having a third fluid therein which is displaceable;
- f) pressure sensor means connected to said fluid output means for sensing said pressure impulses which pass through said second fluid;
- and
- g) means for sealing said fluid container means.
