Barrel-type internal combustion engine
First Claim
1. An engine including a sinusoidal drive cam mounted on a rotatable drive shaft, comprising:
- a tubular rod mounted to a housing, an interior bore of the tubular rod being in fluid communication at both ends with respective sources of lubrication fluid;
a piston configured for reciprocating movement within a respective cylinder bore for engaging and causing rotation of the sinusoidal drive cam and drive shaft, the piston defining an interior region;
a sliding member mounted on the tubular rod and configured to slide thereon, the sliding member defining a fluid path between the interior region of the piston and the interior bore of the tubular rod.

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 including a sinusoidal drive cam mounted on a rotatable drive shaft, comprising:
-
a tubular rod mounted to a housing, an interior bore of the tubular rod being in fluid communication with a source of lubrication fluid; a piston configured for reciprocating movement within a respective cylinder bore for engaging and causing rotation of the sinusoidal drive cam and drive shaft, the piston defining a slot over a portion of its external surface; at least one tube section coupled to the tubular rod and configured to be maintained within the slot during movement of the piston, the at least one tube section defining a fluid path between the slot of the piston and the interior bore of the tubular rod. - View Dependent Claims (6, 7)

8. 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 pair of linear pistons disposed in a respective one of the first and second portions of the cylinder bore; mounted to each piston, a roller that engages the sinusoidal main drive cam; wherein reciprocating linear movement of each piston and its respective roller in a direction parallel to the longitudinal axis causes the respective roller 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 (9, 10, 11)
