    Abstract: A compensation device configured to attenuate pressure variations in an ink printing head is provided. The device includes a first compensation chamber containing ink and having a bottom, an outlet orifice extending through the bottom, and an inlet orifice opposite the bottom; a second compensation chamber containing ink and having a bottom, an inlet orifice extending through the bottom, and an outlet orifice opposite the bottom; and a vent means allowing outflow of air contained in the compensation chambers. The vent means includes a first opening in the first compensation chamber; a second opening in the second compensation chamber operable to be in a lower position with respect to the first opening when the device is in an operating position in which the bottoms of the compensation chambers define lower walls of the corresponding compensation chambers; and an intermediate chamber communicating with the first opening and the second opening.
