Abstract
The present inventions concern rocking-piston engines and rocking-piston compressors of high efficiency. This is achieved by an arrangement in which the piston crown lies on a circular cylinder whose center coincides with the center of the connecting rod bearing and the inner face of the cylinder head lies on a circular cylinder whose center coincides with the center of the crankshaft bearing; and whereby these cylinders are in mutual rolling sealing contact in the vicinity of the top dead center. Additional means help to ensure, for an engine, that the crankshaft is driven before the top dead center or, for a compressor, that optimal compression with regard to flow is achieved with the smallest possible dead volume.
Claims14
A rocking-piston engine with a crankshaft and at least one connecting rod with jointless rocking-piston attached, a radius of curvature of a crown of said rocking-piston being positioned coincident with an axis of the connecting rod bearing and operatively positioned with a cylinder crankcase with at least one of a separate and integrated cylinder head, characterized by the cylinder head having an inner surface with a radius of curvature coincident with an axis of a main bearing of the crankshaft.
A rocking-piston compressor with a crankshaft and at least one attached connecting rod with a rectangular, articulation-less rocking-piston a radius of curvature of a crown of said rocking-piston being positioned coincident with an axis of the connecting rod bearing and operatively positioned with a cylinder crankcase, characterized by the cylinder crankcase having at least one of a separate and integrated cylinder head with a circle-shaped cylindrical inner surface whose radius of curvature is coincident with an axis of the crankshaft bearing, and the rocking-piston crown forming a substantially gas-tight gap with the inner surface of the cylinder head.
A rocking-piston engine with a crankshaft and at least one connecting rod with jointless rocking-piston attached, a radius of curvature of a crown of said rocking-piston being positioned coincident with an axis of the connecting rod bearing and operatively positioned with a cylinder crankcase with at least one of a separate and integrated cylinder head, characterized by the cylinder head having an inner surface with a radius of curvature coincident with an axis of a main bearing of the crankshaft, wherein a top surface of said rocking-piston crown is a rolling sealing contact with said inner surface of said cylinder head when said rocking-piston is substantially in a top dead center position.
