Problems solved by technology

[0011] A particular disadvantage of this prior art is that the cam surface also acts as the piston surface; thus the force acting on the piston is converted into rotational motion reducing efficiency and excessive wear of components

Embodiment Construction

[0032] In the preferred embodiment of the rotary valve internal combustion piston engine, the pair of reciprocating sleeves (1) serve as working cylinders. Although paired sleeves are recommended, only one sleeve may be required if a unique piston is provided.

[0033] Each sleeve surrounds a working reciprocating piston (2) comprising a fixed shaft (3) mounted at right angles to the bore of the cylinder and comprising a pair of rotating rollers (5) mounted on the fixed In constant contact with the fixed pair of cams (6a) integral with the fixed central shaft (6). See Figures 1a, 1b and 3.

[0034] Around the perimeter of each sleeve, each sleeve may be penetrated by a number of equidistant holes (1b) positioned below the level of the piston ring at the position of the bottom dead center of the piston. As further described (14), the function of this hole is to allow the high-pressure air contained in the transfer / purging channel to enter all the gaps between the piston (2) a...

Abstract

The internal combustion engine comprises: a movable piston (2); at least one inlet port (21a, 21b) for the inward flow of the working fluid to the working space; at least one delivery / scavenging port (14) for the inward flow of the working fluid to the workspace; and at least one discharge port (16) for exiting said workspace in which said at least one delivery / clearance port (14) is provided with a closure comprising a reciprocating sleeve (1) unit, the sleeve is parallel to and synchronously coupled with the axis of movement of the piston.

Description

technical field [0001] The present engine relates to improvements in rotary valve internal combustion piston engines of the two-stroke or four-stroke cycle type, and more particularly concerns timing devices for internal combustion piston engines in which a single reciprocating sleeve valve controls the timing of the engine inlet port On and off. Background technique [0002] Such sleeve valves are well known, but have the disadvantage of requiring a separate auxiliary drive mechanism, which adds weight and complexity to all internal combustion engines utilizing such devices and which do not significantly alter the Timed events. [0003] A preferred embodiment of the device is for use in a two-stroke cycle engine. In engines of this type, which are well known in the art, the purging usually occurs through ports cut into the cylinder wall, which are not covered by the piston on its descending or working stroke, and which are covered on its ascending or compression stroke. ...
