Abstract
A radial thermal engine with an improved valve system is disclosed herein comprising intake and exhaust port valve assemblies fluidly connected to respective intake and exhaust ports contained within a cylinder head assembly. Each intake and each exhaust port valve assembly comprises at least one rotatable port cover having spaced apart openings which are periodically alignable to the intake and exhaust ports, respectively.
Claims20
A radial piston engine containing intake ports and exhaust ports on a cylinder head assembly, the engine comprising:
- an intake port valve assembly fluidly connected to the intake ports of the cylinder head assembly, the intake port valve assembly comprising at least one rotatable intake port cover having spaced apart openings each of which are periodically alignable to each of the intake ports;
- an exhaust port valve assembly fluidly connected to the exhaust ports of the cylinder head assembly, the exhaust port valve assembly comprising at least one rotatable exhaust port cover having spaced apart openings each of which are periodically alignable to each of the exhaust ports, respectively.
A radial piston engine containing intake ports and exhaust ports on a cylinder head assembly, the engine comprising:
- an intake port valve assembly fluidly connected to the intake ports of the cylinder head assembly, the intake port valve assembly including at least one independent rotatable port cover driver which drives a rotatable intake port cover;
- an exhaust port valve assembly fluidly connected to the exhaust ports of the cylinder head assembly, the exhaust port valve assembly including at least one independent rotatable port cover driver which drives a rotatable exhaust port cover;
- an engine control unit receiving input data from the engine and transmitting output commands to the port cover driver within the intake port valve assembly and exhaust port valve assembly;
- and
- the rotatable intake port cover having a plurality of openings each of which are periodically alignable to each of the intake ports and
- the rotatable exhaust port cover having a plurality of openings each of which are periodically alignable to each of the exhaust ports.
A radial piston engine having a plurality of cylinders, each cylinder having a cylinder head assembly having an intake port and an exhaust port, and a piston which is connected to a crankshaft, the engine comprising:
- an intake port valve assembly fluidly connected to the intake ports of the cylinder head assembly, the intake port valve assembly including intake ports disposed substantially at a 45 degree angle from an upper surface of the piston and at least one rotatable independent port cover driver which is mechanically driven by the crankshaft and drives a rotatable intake port cover, which lies flat against the cylinder head assembly and includes a plurality of openings each of which are periodically alignable to each of the intake ports, the number of openings in the rotatable intake port cover being equal to at least one greater than the number of cylinders;
- an exhaust port valve assembly fluidly connected to the exhaust ports of the cylinder head assembly, the exhaust port valve assembly including exhaust ports, the exhaust ports substantially opposite the intake ports, and disposed substantially at a 45 degree angle from an upper surface of the piston and at least one rotatable independent port cover driver which is mechanically driven by the crankshaft and drives a rotatable exhaust port cover, which lies flat against the cylinder head assembly and includes a plurality of openings each of which are periodically alignable to each of the exhaust ports, the number of openings in the rotatable exhaust port cover being equal to at least one greater than the number of cylinders.
