Abstract

An apparatus (2) for positive and continuous dispensation of fluids, particularly highly viscous or thixotropic materials, the apparatus having an inlet (12) for delivering fluid to a chamber and at least three pumping means, such as pistons (22) which are arranged to act on the fluid in the chamber sequentially whereby at least one pumping means is acting on the fluid in the chamber at any one time thereby causing continuous discharge of fluid from an outlet (38). Two or more apparatuses may be linked together and controlled independently to allow production of two or more component mixtures in definite mixed ratios. The ratios may be varied by simple adjustment of the controls. <IMAGE>
