ABSTRACT:
A wobble plate of the type for operating in a variable displacement compressor including a plurality of pistons operatively connected to the wobble plate by a plurality of dumb-bell like piston rods having spherical end portions and a connecting rod extending therebetween. The wobble plate includes a plurality of sockets including an integral lip for retaining the spherical portion of the piston rods contained within each of the sockets against axial displacement and a passageway extending radially outwardly from each of the sockets and opening to a peripheral edge of the wobble plate for allowing insertion of the piston rods from a direction substantially perpendicular relative to the central axis of the wobble plate. Plugs disposed within the passageway prevent inadvertent radial displacement of the spherical ends of the rod members from the sockets.
