Patent ID: 10072568

Abstract:
A variable displacement hypocycloidal crankshaft includes a crankshaft, a hypocycloidal gear assembly, an external pin, and an angle-setting device. The crankshaft mounted in a chassis houses the piston assembly. The hypocycloidal gear assembly includes an internal gear and an external gear. The crankshaft is mounted on the chassis coaxially with the internal gear and rotates freely in the center of the internal gear. Then, the external gear is mounted on the crankshaft movable pin and engaged with the internal gear thereby rotating the external gear. The external pin operably engages the piston assembly. The angle-setting device mounted on the chassis operably engages the internal gear. The angle-setting device is coaxial to the hypocycloidal gear assembly for selectively varying the linear displacements of the piston assembly. The external gear meshes with the internal gear for converting the continuous rotation of the crankshaft to varying linear displacements of the piston assembly.
