ABSTRACT:
A synchronous twin reciprocating piston apparatus includes a cylinder and a number of stator assemblies mounted in fixed relation thereto. The stator assemblies are constructed so as to generate a radial magnetic field in a number of regions near to each end of the cylinder. The apparatus also includes a pair of piston-magnet assemblies, each having a piston slidable within an end of the cylinder, and a number of compound permanent magnet systems located within the regions. Each compound permanent magnet system includes a first section magnetized in a direction radial relative to the cylinder axis and a second section, axially displaced from the first, magnetized in the opposite direction. When the stator assemblies are excited with an alternating current, the piston-magnet assemblies reciprocate axially relative to said cylinder, and synchronously with the frequency of the applied current. The pistons then generate a pulsating pressure within the cylinder.
