Water jet injection device for use with dispensers for producing and dispensing beverages mixed of fruit syrup or concentrate and water

Abstract From the Canadian patent

A water jet injection device for use with mixed beverage dispensing machines is provided, wherein a bushing-type sealing element which fulfills several functions is placed in the injector housing. In particular the sealing element sealingly separates the mixing chamber from the rearward section of the injector housing in reliable manner and further acts as a non-return valve hermetically sealing the mixing chamber against the supply conduit for fruit syrup or concentrate when the injector in the mixing chamber is inoperative and, at the same time the sealing element provides a seal when an intake conduit or the like is connected with the lateral intake opening of the injector housing.
