Abstract
Abstract A oscillatory motion coupler which when excited in oscillation transfers oscillatory motion induced in a cylinder to a piston free to oscillate within that cylinder. When excited at the natural frequency of the coupler the oscillatory motion can be amplified. The piston includes a piston rod to transfer the force on said piston to the exterior of the cylinder. Associated with the cylinder are passive pneumatic passages which offset the natural tendency of the piston oscillation center to move from its original location to one end of the cylinder or the other. The passages maintain the center of oscillation within the confines of the cylinders so as to prevent impact of the piston against either end thereof.
