RECIPROCATING COMPRESSOR
The invention relates to a reciprocating compressor having a wobble plate (30) and having at least two reciprocating pistons (25), wherein the wobble plate (30) comprises at least one wobble cam (31, 32) and at least one balance weight (38, 39), which are arranged on a first ring face (41) of a plate main body (40), and the reciprocating pistons (25) each have a piston axis K, which are arranged on a common circle line of a circle having a circle diameter dp, and wherein the wobble plate (30) has - a wobble plate mass m, - a density ρ, - a center of gravity position y, which is dependent on a tilt angle ψ of the wobble plate (30), - a thickness z, which corresponds to the distance of the first ring face (41) to a parallel, second ring face (41, 42) of the plate main body (40), and - in operation, a wobble plate imbalance dependent on the tilt angle ψ of the wobble plate (30), wherein the following applies to an imbalance ratio M between the wobble plate imbalance and a reference imbalance: (I) wherein the reference mass mref is determined from the thickness z of the plate main body (40), the circle diameter dp and the density ρ of the wobble plate (30), and wherein the following applies to a quadratic average MRMS of the imbalance ratio M over a plurality of, in particular all, discrete, full tilt angles ψ in the tilt angle range between ψ=0° and ψ=23°: (II) wherein MRMS < 0.045.
