Abstract
The invention provides an internal combustion engine suitable for use with a model aircraft comprising an outer housing, a cylinder disposed within the outer housing and rotatable about an axis W—W, and a power transmission means comprising a reciprocable piston, a connecting shaft connecting the piston to a crankshaft having a bevel drive gear that meshes with a bevel gear ring disposed at one end of the cylinder, whereby a linear movement of the piston is converted into a rotational movement of the cylinder.
Claims19
An internal combustion engine (1) comprising
- an outer housing (2);
- a rotatable cylinder (3) disposed within the outer housing (2), the cylinder defining an inner chamber (17);
- a valve means incorporated with the outer housing and the cylinder to provide communication with the inner chamber;
- a reciprocable piston (4) disposed coaxially within the cylinder;
- a power transmission means coupled with the cylinder (5) comprising
- a housing block (27),
- a crankshaft (29) disposed in the housing block,
- a connecting shaft (28) suitably attached at one end to the crankshaft and suitably attached at an opposing end to the piston, and
- a bevel drive gear (30) coaxially fixed onto the crankshaft to mesh with a bevel gear ring (19) disposed coaxially at one end of the cylinder to connect the crankshaft with the cylinder, whereby the power transmission means converts a linear movement of the piston into a rotational movement of the cylinder;
- and
- an output drive means (6) incorporated with the rotatable cylinder and disposed coaxially with respect to the cylinder.
