Abstract
A rotary cam radial engine formed of two primary components engaged at a mid section to allow for an easy repair to the vehicle. The device features a body having radially oriented apertures; and a plurality of pistons in a respective reciprocating engagement, within each respective said cylinder. The pistons are driven by low pressure fluids and/or a vacuum and the engine being formed of two main components can be taken apart without tools for maintenance and reconfiguration.

1-20. (canceled)
A rotary cam radial engine, comprising:
- an engine assembly comprising:
- an engine body defining a valve cavity;
- and
- one or more piston assemblies attached to and extending radially from the engine body and in fluid communication with the valve cavity, each piston assembly including a cam follower;
- and
- a first cam ring assembly comprising:
- a first cam ring defining a first cam surface including a plurality of compression lobes and a plurality of exhaust cavities;
- and
- a first central valve assembly attached to the first cam ring,
- wherein the first central valve assembly is removably and slidably insertable into the valve cavity of the engine assembly to permit relative rotation between the first cam ring assembly and the engine assembly with the cam follower of each piston assembly following the first cam surface during the relative rotation.
A rotary cam radial engine kit, comprising:
- an engine assembly, comprising:
- an engine body defining a valve cavity;
- and
- one or more piston assemblies attached to and extending radially from the engine body and in fluid communication with the valve cavity, each piston assembly including a cam follower;
- and
- a plurality of cam ring assemblies, each cam ring assembly comprising:
- a cam ring defining a cam surface including a plurality of compression lobes and a plurality of exhaust cavities;
- and
- a central valve assembly attached to the cam ring,
- wherein the central valve assembly of each cam ring assembly is removably and slidably insertable into the valve cavity to permit relative rotation between the respective cam ring assembly and the engine assembly with the cam follower of each piston assembly following the respective cam surface.
A cam ring assembly for use in a rotary cam radial engine having a central valve cavity, the cam ring assembly comprising:
- a cam ring defining a cam surface including a plurality of compression lobes and a plurality of exhaust cavities;
- and
- a central valve assembly attached to the cam ring,
- wherein the central valve assembly of the cam ring assembly is configured for removable and slidable insertion into the central valve cavity, thereby permitting the cam ring to rotate about an axis passing through the central valve assembly.
