<p>VARIABLE CAPACITY COMPRESSOR: A controlled, variable displacement swash plate compressor is provided with means for controlling the capacity by pivoting the swash plate (64) about the drive shaft (24) axis to vary the effective pumping capacity. The position of the swash plate (64) with respect to the drive shaft axis is a function of the pressure maintained inside the crankcase, said position being a result of the various forces acting on the pistons (80), including the underside of the pistons where crankcase pressure is applied. A cam surface (56) is provided to maintain a fixed top dead center position at all displacements, as well as an improved universal joint mechanism (82,83,84) to anchor the swash plate against rotation.</p> |
