Abstract: A fluid dispenser is disclosed where a backoff distance is determined and implemented to prevent leakage while dispensing sequentially an accurate, precise amount of fluid substantially independent of the fluid remaining in a syringe-type dispenser. The fluid characteristics of the fluid, e.g. viscosity, surface tension, etc. affect the backoff distance that may be determined heuristically for fluid type, amount of fluid remaining in the syringe and amount to be dispensed. Once the fluid characteristics are known, the dispensing may be accomplished automatically with a processor loading new drive and backoff steps to a motor controller.

Abstract: Device for pumping viscous materials, particularly sealant and grease, without dripping and method of the same are characterized by storing a predetermined portion of the driving energy in form of an angular and/or linear displacement of a torsional spring. This very portion of the stored energy will be released at the end of the operation when the operator let go the trigger, whereby the released energy will drive the final transmission and the end part of the final transmission to move backwards for a predetermined amount of displacement. This backwards movement of the end part of the final transmission causes the volume of viscous material to expand suddenly; this expansion of the volume of viscous material compensates the compression of the viscous material from the dispensing process, which will also draw back the viscous material on its way outward for to work and for to drip.
