ABSTRACT:
A noiseless supporting mechanism of a wobble plate in a compressor unit of the wobble plate type comprises a support member having a spherical convex surface at its end. The support member is elastically supported on the cylinder block and is disposed in a hollow portion of the wobble plate with the spherical convex surface being in contact with a spherical concave bottom surface of the hollow portion, to support the wobble plate. A plurality of equiangularly-spaced projections are supported around the central axis of the supporting member and are disposed in corresponding recesses formed in an inner surface at an opening edge of the hollow portion to prevent the wobble plate from rotating. The wobble plate thus nutates along the spherical convex surface by the rotation of the associated cam rotor.
