ABSTRACT:
The invention is a new linkage for connecting the piston and the piston actuator in a high pressure pump. All of the compression forces transmitted from the piston actuator to the piston by this linkage will be axial forces parallel to the axis of the piston since the linkage will not transmit forces to the piston which are transverse to its axis. This linkage allows the use of hard brittle materials such as ceramic materials in the piston because any misalignment between the axises of the piston actuator and the piston will not result in bending forces being applied to the piston which would cause it to break.
