Abstract:
1. A pressure drop compensation member suitable to be placed in a fluid dispensing channel, the pressure drop compensation member comprising: (a) a sleeve; (b) a piston adapted to be acted upon by a fluid in a first direction, the piston comprising one or more flow slits through which all of said fluid flows through the piston, the piston comprising: (c) an elastic member capable of acting on the piston in a second direction opposite to the first direction; wherein the piston is slidably movable within the sleeve to adjust the area of each of the one or more flow slits, subject to a minimum area of each of the one or more flow slits always being available for fluid flow, and wherein, in use, if the pressure exerted by the fluid on the piston drops, the elastic member acts to move the piston in relation to the sleeve to increase the area of each of the one or more flow slits in order to maintain a substantially constant flow of fluid through the fluid dispensing channel.
