ABSTRACT:
The invention provides a cell having a variable volume chamber and a fluid supply circuit for an ink jet printing head which is equipped therewith. The cell includes a variable volume chamber (1) connected to a pressure sensor (5) and to at least a pair of valves (7, 9) each associated with a restriction (8, 10). The variation of volume is obtained by means of a piston actuated by an eccentric (3) secured to the rotor of a stepping motor (4). The maximum pressure difference generated at the ends of the restrictions (8, 10) is used to measure the viscosity of the fluid which flows through the corresponding valves (7, 9).
