Abstract: The invention relates to a method for checking the function of at least one PTC heating element which is used in a device for providing a liquid additive. The at least one PTC heating element is connected to a voltage source via electric conductors. According to the method, a starting current with a first value is provided at a specified operating voltage in a step a). Then, in a step b), a monitoring process is carried out in order to determine whether the starting current with the first value is provided for a minimum duration, said minimum duration having a value of at least seconds. The method is used in particular for on-board diagnoses of a device for providing a liquid additive.

Abstract: A method for operating a device for the dosed supply of a liquid includes: detecting a demanded dose amount of the liquid; activating an electric drive of a pump to move a seal in a delivery direction from an inlet to an outlet to deliver the liquid by application of an operating voltage to the electric drive; stopping operation of the pump when the delivered amount of the liquid corresponds to the demanded dose amount; stopping movement of an eccentric; and maintaining a holding voltage at the electric drive. In response to the holding voltage, a holding torque is exerted on the eccentric and a movement of the eccentric counter to the delivery direction is prevented.

Abstract: A pump for conveying liquid includes a pump housing with an inlet and an outlet. An eccentric mounted at the housing rotates about an axis relative to the housing. A deformable element is disposed between the housing and the eccentric. A delivery duct from the inlet to the outlet is formed by the deformable element and a circumferential housing surface. The deformable element is pressed in sections against the housing by the eccentric to form a displaceable seal of the delivery duct and a closed pump volume in the delivery duct, which can be displaced along the delivery duct from the inlet to the outlet by a movement of the eccentric to convey liquid. A channel cross-section of the delivery duct is limited by the circumferential surface, a set-back duct surface of the deformable element and a contact seal between the circumferential surface and the deformable element.
