ABSTRACT:
High Pressure reciprocator components for reciprocating machines particularly internal combustion engines, the components include a multiple ring, single groove, piston seal having stacked ring elements with top contraction rings to block cylinder pressure from entry behind the rings and bottom expansion rings to contact the cylinder and seal with constant force throughout the piston cycle; a wristpin bearing assembly for tandem, toggle motion connecting rods connecting a single piston with dual, counter rotating crankshafts, the bearing assembly having a bearing seat for positioning juxtaposed wristpins in mutual, limited rolling contact to cancel side components of piston thrust force and frictions; and, a cross channel pressure converter interconnecting an exhaust conduit with a compressed air conduit with a channel having a free floating piston therein to equalize exhaust and intake pressures in a reciprocator to boost intake pressures or purging and charging the cylinder.
