Abstract
A synthetic vacuum generator has a case enclosing an interior cavity with an aperture through the case in communication with the cavity. A piston and a check valve are mounted in the case in fluid communication with the cavity and the aperture. The piston and check valve are configured with symbiotic resonant response to establish an outflow there through and inducing an inflow through the aperture upon reciprocation of the piston at a predetermined frequency.
