APPARATUS FOR REDUCING NOISE IN A CRYOCOOLER SUCH AS FOR MAGNETIC RESONANCE IMAGING SYSTEMS |
| 摘要 |
An assembly for operating a cryocooler pedestal is provided. The assembly is operable when in use to provide a cryocooler pedestal with cyclical gaseous connection to high pressure and low pressure gas supply lines, and has a return conduit through which gas is caused to flow from the cryocooler pedestal into the low pressure supply line. The assembly further comprises a dispersion chamber adjacent the return conduit and in flow communication therewith through a plurality of orifices so as to reduce acoustic noise. The assembly has particular application in cooling a Magnetic Resonance Imaging system. |
