More Information
Summary:The invention is a 180° reciprocating piston compressor comprising additional eccentric disc linkage between the crankpin and the connecting rod. The additional linkage lessens the compression above the piston during start-up and limits the electrical motor shaft load at design operating conditions lowering the starting current surge when bringing the system up to starting speeds. The additional disc eccentric linkage also lessens the torque load on the motor during motor normal operating speed.
