Distributeur mobile à injecteur rotatif applicable au refroidissement de gaz.

摘要

The invention comprehends a rotary-injector type distributor interposed between a pressure fluid intake and one or more receiving pulse tubes, characterized in that the rotary injector has on either side of its ejection orifice a leading edge and a trailing edge, as considered in the direction of rotation, of an angular extent such that the leading edge can cover the receiving-tube entry past which the injector will move, the leading edge uncovering such entry only in proportion as the injector ejection orifice moves past the entry, and in turn the trailing edge gradually covers the entry in proportion as the injector ejection orifice departs from the entry, to ensure in both cases that in the tube-filling phase the fluid is not exhausted from the tube before having been operative therein.
