Abstract: A pump system for an infusion system includes a linear drive (36, 36?) which minimizes the space occupied by the pump components in a portable housing (10, 10?). A motor (34) and a motor drive shaft (42) are arranged in parallel with, and adjacent to a syringe (14, 14?) and lead screw (94, 94?). A gear box (54) connects the drive shaft and lead screw to transfer rotational movements between them. A piston driving member, such as a cone (116) or drive nut (116?) converts the rotational movement of the lead screw into linear motion of a syringe piston (24).

Optionally, a proximity sensor (170) is used to ensure that the cone and the piston (24) are abutting during dispensing. Alternatively, a clamping member (350) selectively clamps the lead screw (94?) against linear motion in at least a dispensing direction.

Abstract: A pump transfers syrup through a supply line and through a valve assembly for mixing with ice cream in a mixing chamber to form a frozen dessert or milkshake. When the syrup flows through the passive valve, the pressure along the supply line increases.
