US Patent 5159961: Inflator/deflator accessory for air compressor
US 5159961 · granted 1992-11-03
Abstract
An accessory for inflating and deflating inflatable articles comprises a conduit 13, an intake 17, an outtake 19 and an injector 35. In use, conduit 13 functions as a venturi tube for rapid inflation and deflation of inflatable articles, preferably, articles having a large, low pressure air volume. For inflation, outtake 19 is connected to the inflatable article. For deflation, intake 17 is connected to the inflated article. For inflation and deflation, a source of pressurized air, preferably, an electric air compressor is connected to injector 35.

Claim 1
A device for inflating and deflating inflatable articles comprising: a conduit having a sidewall defining a passageway, an intake having an opening and an outtake; an injector fixed to and extending through the sidewall, the injector having an opening external to the sidewall and connectable to a source of pressurized air and having a small orifice within the passageway for expelling a small volume, highvelocity, low pressure air stream; an inlet in the sidewall; and a closure for the inlet movable between an open position for permitting airflow through the inlet and a closed position for preventing airflow through the inlet.
