PURPOSE:To cool high-temperature section, prevent generation of oil sludge and improve refrigerating capacity by providing a cylinder head with an oil reservoir for reserving oil. CONSTITUTION:Inclined grooves 8b, 9b, 12d are provided at the upper parts of a cylinder 8, a valve plate 9 and the cylinder head 12 to introduce lubricating oil discharged out of a crank shaft 7 through a cross slider 10. The bag-like oil reservoir 12, provided in said cylinder head 12, is constituted so that the lubricating oil can be supplied through the inclined grooves 8b, 9b, 12d while an oil extracting small hole 12f, for discharging a part of the lubricating oil, is provided on the bottom of the oil reservoir 12b to facilitate to replace the lubricating oil with new lubricating oil. |
