    Patent number: 10876528
    Abstract: A self adjusting gear pump (10) for an ice cream freezer and a control unit (20) for adaptively controlling the closing pressure (PCLOSE) of a pump for an ice cream freezer. The gear pump system comprises a pump casing (11), an inlet (12) for receiving a liquid food product of ice cream mix, an outlet (15) for transferring the ice cream mix into a freezing cylinder (41) of the ice cream freezer (40), wherein the pump (10) is closed by supplying a closing air pressure onto a moveable pump cover (16) of the pump via at least one hole (191, 192) provided straight through the pump casing (11), thereby moving said moveable pump cover (16) against the star wheel (14) and a control unit (20) for supplying a calculated closing air pressure (PCLOSE) to the pump by means of the air pressure regulator (100).
