Latest Patents

Kosaka's latest patents include a piston cooling device and an oil pan for an engine with a shield member covering an air hole of an oil sensor. The piston cooling device improves the cooling efficiency of a piston by utilizing oil injected from an oil jet, which is supplied to a cooling passage within the piston. This design reduces the amount of cooling oil needed when the engine operates at maximum output. The oil jet injects oil at every stroke of the piston, creating a two-phase plug flow of gas and oil in the cooling passage during peak performance.

The oil pan patent features an oil level sensor designed to detect oil levels within the engine oil pan. This sensor includes a mounting section and a sensing section, with an air hole at the upper end of the cover member. The air hole is surrounded by a shield member attached to a baffle plate, preventing splashed engine oil from entering the sensing section through the air hole. Additionally, a clearance for venting air is formed between the tubular portion and the baffle plate.
