ン防止装置。[Scope of Claim for Utility Model Registration] (1) In the valve arm chamber of a horizontal engine, a valve guide that supports a horizontal exhaust valve stem is provided in a protruding manner from the cylinder head toward the valve arm chamber, and a stem seal is provided at the tip of the valve guide. Attach the lubricating oil droplet introduction hole to the lower surface of the valve guide exposed in the valve arm chamber between the stem seal and cylinder head, and provide a droplet shielding part that extends between this hole and the lower half of the valve arm. An oil-down prevention device for horizontal engines that prevents the direct introduction of droplets generated by the swinging of the lower half of the valve arm. (2) A valve arm chamber is formed between the cylinder head and the valve arm cover, and lubrication is achieved within the valve arm chamber by directing the lubricating oil passage in the valve arm shaft to the inner surface of the valve arm cover through the nozzle of the valve arm boss. An oil down prevention device for a horizontal engine according to claim 1, which is capable of generating oil splashes. (3) The lubricating oil droplet introduction hole is provided at or near the lower end of the valve guide.Claim No. 1 for Utility Model Registration
Oil-down prevention device for horizontal engines as described in . (4) The oil down prevention device for a horizontal engine according to claim 1, wherein the splash shielding portion is formed integrally with the cylinder head or by being fixed to a separate object.
