Rotary-linear power device

Apparatus for converting between rotary and linear motion, said apparatus comprising:

• a generally cylindrical member constrained for rotation about a predetermined axis, said member having outer and inner diameter surfaces and having first and second cam track means formed in said outer and inner surfaces, respectively;
• and
• first and second plurality of axially reciprocable pistons disposed radially outwardly and inwardly, respectively, of said cylindrical member;
• said first and second plurality of pistons being operably connected to said first and second cam track means, respectively, for simultaneous rotation of said cylindrical member and linear axial reciprocation of said pistons.

Apparatus for converting between rotary and linear reciprocating motion, said apparatus comprising:

• shaft means constrained for rotation about a predetermined axis, said shaft means having an outer diameter formed with a first cam means;
• sleeve means coaxial with said shaft means and constrained for rotation about said axis, said sleeve means having an inner diameter surface with a second cam means;
• and
• a plurality of axially reciprocable pistons disposed radially between said shaft means and said sleeve means, said pistons being operably connected between said first and second cam means for simultaneous rotation of said shaft means and said sleeve means and linear reciprocation of said pistons.

A machine comprising:

• a plurality of radially reciprocable members angularly spaced and disposed radially about a predetermined axis;
• a plurality of axially reciprocable members angularly spaced on a predetermined diameter about said axis;
• and
• a sleeve member constrained for rotation about said axis and disposed between said radial members and said axial members, said sleeve being in torque transmitting connection with said radial and said axial members.

Apparatus adapted for use in a pump, a compressor, an internal combustion engine, or like machinery, said apparatus comprising:

• a housing;
• shaft means journaled in the housing for rotation about a predetermined axis;
• a plurality of axially extending cylinders connected to said housing and disposed radially of said axis on a first predetermined diameter;
• a plurality of axially reciprocable pistons slidably disposed in said cylinders and defining variable volume axial chambers there in;
• a plurality of radially extending cylinders connected to said housing and disposed radially of said axis on a second predetermined diameter;
• a plurality of radially reciprocable pistons slidably disposed in said radial cylinders and defining variable volume reciprocal chamber there in;
• and
• sleeve means rotatably mounted in said housing and disposed between said first and second diameters;
• said shaft means having first cam track means operably engaging said axial pistons in torque transmitting relation for simultaneous reciprocation of said axial pistons and rotation of said shaft means,
• said sleeve means having second track means operably engaging said axial pistons and having cam lobe means operably engaging said radial pistons for simultaneous (A) reciprocation of said axial pistons, (B) reciprocation of said radial pistons, and (C) rotation of said sleeve means.
