Claims

[Scope of utility model registration request]

Three-dimensional lattice-like skeletal frames 8, 34 are integrally formed on the outside of the cylinder barrel portion 7 and crankshaft portion b of the engine block E, and rigid membrane members 9, 35 are integrally formed on the outside of the skeletal frames 8, 34. In the engine, an oil reservoir _R0 is defined by the skeletal frames 8, 34 and the rigid membrane members 9, 35, and this oil reservoir _R0 and crank chambers C1 _to C formed in a closed shape are connected to each other.
₄ through check valves 62 ₁ to 62 ₄ such as reed valves and an oil passage 60 , and the oil passage 60 is provided along the outer surface of the side wall 18 having the refrigerant jacket 13 of the cylinder barrel portion 7 . The engine lubricating device is further characterized in that the oil return port 79 of the cylinder head Hc is opened directly above the oil reservoir _R0 .
