Abstract
A wobble plate type compressor is equipped with a device which can be selectively activated in a manner to induce the wobble plate to assume a position wherein the displacement of the compressor is reduced to zero and thus obviate the need for a clutch for such purposes. The device further includes an arrangement which biases the wobble plate toward a position wherein a positive displacement of the compressor will occur when in a non-activated state. The strength of this bias is insufficient to interfere with the control of the wobble plate inclination by the pressure prevailing in the chamber in which the plate is disposed.
