ABSTRACT:
An apparatus providing for the generation, control and application of power to a cyclic functioning machine, using fluids under pressure to transmit and control energy by means of a rotary, segmented cam wheel. The cam wheel provides a plurality of interchangeable segments formed into a rim portion with axially spaced complementary counteracting cam faces formed about opposite rim ends. An individual cam follower, carried on a piston rod of a related hydraulic cylinder, coacts with each of the cam faces to accurately regulate the flow of hydraulic fluid to and from a working cylinder of a machine to provide timed and synchronized machine functions through the control movement of the working cylinder. The contoured configuration of the cam faces are arranged to provide for a desired acceleration and retardation of machine motions. Further, variable speed drive means, employed to drive the cam wheel, provides a timing adjustment between machine cycles.
