This design utilizes spherical balls that function as pumping members and also function as bearing loads. The housing includes channels that are used to convert rotary motion to true linear reciprocating motion relative to the center of operation by use of modified involute profile curves. The channels have an enlarged radius of curvature, four (4) contact point designs, and an arch design depending upon application and loads, etc. A variable vane shaft and variable seal plug have a make-before-break design that eliminates damaging high pressure spikes d...
[ Having thus described the invention, it is now claimed:] [1.] A variable displacement load device having a center of operation, comprising:at least two spherical balls having a radius of curvature;a front cover housing having a port, and channel, said port able to direct inlet pressure to said mechanical face seal, said channel having an involute profile, a depth, a tangent, and a radius of curvature, said channel involute profile having four regions comprised of two regions of involute curves, a radius dwell region, and a blended radius region;a rotor...
