Barrel-type internal combustion engine
First Claim
Patent Images
1. An engine, comprising:
- a rotatable shaft;
a cam disc mounted to the rotatable drive shaft, the cam disc having a surface that includes a planar region and a non-planar region;
an actuation mechanism in contact with the surface;
a valve coupled to, and configured to be actuated by, the actuation mechanism such that the valve is caused to be in a first one of an open and a closed state when the actuation mechanism is in contact with the planar region of the surface, and the valve is caused to be in a second one of an open and a closed state when the actuation mechanism is in contact with the non-planar region of the surface.

Abstract
An engine, e.g., a cam drive, barrel-type internal combustion engine, that includes: a main drive shaft defining a longitudinal axis; a sinusoidal main drive cam rigidly attached to the main drive shaft; a plurality of cam members that are in contact with the sinusoidal main drive cam and that are configured to follow the sinusoidal main drive cam, wherein rotation of the sinusoidal main drive cam corresponds to reciprocating linear movement of each of the plurality of cam members in a direction parallel to the longitudinal axis; for each cam member, a pair of linear pistons disposed on opposite sides of the cam member for reciprocating linear movement within respective cylinder bores.

5. An engine, comprising:
-
a rotatable shaft; a cam disc mounted to the rotatable drive shaft, the cam disc having a surface that includes a planar region and a non-planar region; a rotatable arm; a pair of rollers mounted to the rotatable arm, each roller in rolling contact with the surface; a valve coupled to, and configured to be actuated by, the rotatable arm such that the valve is configured to be in a first one of an open and a closed state when at least one of the pair of rollers is in contact with the planar region of the surface, and the valve is configured to be in a second one of an open and a closed state when at least one of the rollers is in contact with the non-planar region of the surface. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. An engine, comprising:
-
a main drive shaft defining a longitudinal axis; a sinusoidal main drive cam non-rotatably attached to the main drive shaft; a cylinder bore, a first portion of the cylinder bore being disposed on a first side of the sinusoidal main drive cam and a second portion of the cylinder bore being disposed on a second side opposite the first side of the sinusoidal main drive cam; a pair of linear pistons, each linear piston disposed in a respective one of the first and second portions of the cylinder bore; and mounted to each piston, a pair of rollers that engages the sinusoidal main drive cam, wherein reciprocating linear movement of each piston and its respective rollers in a direction parallel to the longitudinal axis causes the respective rollers to be in rolling contact with the sinusoidal main drive cam for rotating the sinusoidal main drive cam and the main drive shaft. - View Dependent Claims (14, 15, 16, 17, 18)
