Description: |
| Abstract:
This invention relates broadly to internal combustion engines, and it has for its primary object to provide an engine in which piston valves are employed for controlling the inlet and the exhaust of the gases, securing greater efficiency with a minimum expenditure of waste energy.
A further object is to provide, in a gas engine, an exhaust valve of the piston type which is so located that it is directly acted upon by the exploding gas, and the impulse given thereto is communicated to the crank-shaft, materially assisting at the commencement of the power stroke in carrying over center the crank with which the associated power piston is connected. A still further object is to provide an engine having an inlet valve of piston type which is so arranged that it compresses air in a pocket during the suction and compression strokes of the power piston and is then acted upon by the reexpanding air during the power stroke for further assisting in carrying said crank over center.
Claim:
In an internal combustion engine, a power cylinder, a piston reciprocating therein, inlet and exhaust valve chambers located laterally of said cylinder, inlet and exhaust ports respectively provided in the walls of said chambers, reciprocating piston valves in said chambers, the exhaust chamber being in permanent open communication with the cylinder above the limit of upward movement of its valve, and the inlet chamber being in communication with said cylinder through a side-opening passage which is iio closed by its valve during the power stroke of the piston so that the side wall of said valve receives the impact of the explosion, said passage being so located with respect to the inlet port that unobstructed communi- 1 cation is had therebetween over the extreme upper end of said valve throughout the suction stroke of the piston. |
