Abstract: A frozen dessert dispenser includes a heat-insulating box, a cooling unit for cooling an atmosphere in the heat-insulating box, a dispensing cylinder including a piston ascended and descended by an operating fluid and a pack accommodating chamber in which a frozen dessert pack is accommodated, a pump supplying and discharging the operating fluid to and from a pressure chamber defined in the dispensing cylinder, and a usually closed operating fluid introducing port disposed in the cylinder. The operating fluid introducing port is opened so that the operating fluid is introduced into the pressure chamber, when the piston reaches a bottom dead point.

Abstract: A frozen dessert dispenser includes a freezing compartment accommodating a frozen dessert dispensing cylinder, a dispensing section provided on an outer wall of the freezing compartment, the dispensing section including a vertically extending dispensing passage and a valve element slidably provided in the dispensing passage, and a connecting pipe communicating with a side of the dispensing passage and projecting into the freezing compartment to be connected to a discharge side of the dispensing cylinder. A portion of the dispensing passage communicating with the connecting pipe is closed and opened by the valve element and the connecting pipe is detachably attached to the dispensing passage.
