Embodiment Construction

[0027] Embodiments of the present subject matter may, among other possible advantages, provide systems, methods, techniques, etc. to enable a lubricant seal between a sleeve valve and other components of an engine block or internal combustion engine to remain stationary during operation. In particular, the effectiveness of the lubricant seal is improved by the provision of improved sealing means and / or sealing means which move with the sleeve valve.

[0028] figure 1 A partially cut-away perspective view showing an illustrative but non-limiting example of an internal combustion engine 100 in which sleeve valve sealing as discussed herein may be employed. Sleeve valves that are sealed in a manner consistent with embodiments of the present subject matter may be used in opposed-piston engines, including examples other than those discussed herein, as well as in other engine configurations where the pistons are not in contact with one or more other Pistons share a combustion cham...

Abstract

Leakage of a liquid (e.g. a coolant and / or a lubricant) past a sleeve valve to a port in communication with a combustion chamber of an internal combustion engine can be prevented by use of a substantially ring-shaped seal, which can be carried on the sleeve valve or disposed on a stationary part of the internal combustion engine.

Description

[0001] Related Application Cross Reference [0002] This application claims priority to US Provisional Application No. 61 / 837,101, filed June 19, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The subject matter described herein relates to engines including one or more ports controlled by movement of one or more sleeve valves. Background technique [0004] A sleeve valve is a type of valve that can be used in internal combustion engines, including but not limited to opposed-piston engines in which two pistons share a single cylinder, and can also be used in engines where each piston reciprocates in its own cylinder . Such valves typically form all or part of the cylinder walls defining the combustion chamber within the cylinder. In some variations, one or more sleeve valves may reciprocate back and forth substantially parallel to an axis on which one or more pistons reciprocate to open and close the inlet and / or outlet ports at ap...
