FORCE AMPLIFYING DRIVER SYSTEM, JETTING DISPENSER, AND METHOD OF DISPENSING FLUID

摘要

A force amplifying driver system including an actuator with a powered actuating member mounted for movement along a first distance “X”. A driven member mounted for movement along a second distance or working distance “Y” which is less than the first distance “X”. The powered actuating member is movable through a gap “Z” before being mechanically coupled with the driven member and subsequently moves with the driven member along the second distance “Y”. Energy is transferred from the powered actuating member to the driven member along the second or working distance “Y”. The force amplifying driver system may be used for actuating a fluid jetting dispenser.

1. A method of dispensing a jet of fluid using a dispenser including an actuating member and a valve including a valve member with a tip and a valve seat located in a fluid chamber, the method comprising:
moving the actuating member under power through a gap along an axis; mechanically coupling the actuating member with the valve member at the end of the gap to provide an amplifying force to the valve member; moving the actuating member and the valve member together along a working distance along the axis using the amplifying force; moving the tip of the valve member through the fluid chamber along the axis to dispense a jet of the fluid from the valve; and engaging the tip with the valve seat at the end of the working distance to discharge the jet of fluid.
