A compressor assembly includes a compressor having a cylinder and a connecting rod in a connecting rod plane. The connecting rod includes a compressor piston and a connecting rod bearing. The compressor assembly includes a drive having an axis of rotation, a drive shaft, and a housing. The drive shaft is mounted in a drive shaft bearing and has a connecting rod side end and a connecting rod remote end. The drive shaft has a connecting-rod receiving portion which is arranged eccentrically to the axis of rotation of the drive at the connecting rod side end.

A compressor having curved connecting rods, comprising cylinders (8), pistons (9), piston pins (10), curved connecting rods (11), a swing rod (12), a crank pin (13), a crankshaft (14) and the other components; when the compressor having curved connecting rods works, a power machine driving the crankshaft (14) to rotate, the rotation of the crankshaft (14) driving the crank pin (13) to push the swing rod (12) to swing left and right, and the movement, towards the left and right, of the swing rod (12) driving the curved connecting rods (11) and the pistons (9) to reciprocate within the cylinders (8) and perform work in a compression manner.

Systems and methods are described for a reciprocating mechanism. The system includes at least one axially translating y-axis component configured to reciprocate substantially along a y-axis with a reciprocating motion of a piston assembly relative to a base. The system also includes at least one x-axis component slidingly coupled via at least one bearing assembly to and translating with the at least one y-axis component along the y-axis. The at least one x-axis component is configured to reciprocate substantially perpendicularly to the y-axis relative to the at least one y-axis component, and includes an orbital output component and an orbital linking component disposed substantially concentric with the orbital output component. The system also includes a stationary output component rotatably attached to the base in a direction that is substantially perpendicular to both the x-axis and y-axis, and a stationary linking component rotatably attached to the base in a direction that is substantially concentric with the stationary output component.
