Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
As shown in Figs 1-4, a kind of cylinder head long-pending oil recovery structure, including cylinder head body 1, in figure on cylinder head body 1
Side is air inlet side, and downside is exhaust side, and left side is rear end, and right side is front end, and air inlet side is equipped with cylinder bolt in cylinder head body 1
Hole plateau 11,11 middle part of cylinder bolt hole plateau are equipped with the bolt hole 111 for penetrating through cylinder head body 1 straight down, bolt hole 111
Aperture for 8~12mm, cylinder head body 1 is equipped with the low-lying long-pending oil area 13a in oil pocket front end, oil pocket middle-end successively to the back-end by front end
The low-lying long-pending oil area 13b and low-lying long-pending oil area 13c in oil pocket rear end, with reference to shown in Fig. 2, the cross section of oil pocket is near in cylinder head body 1
Like a up-side down triangle, structure type is low for air inlet side, and exhaust side is high so that it is low-lying that remaining lubricating oil flows to air inlet side oil pocket
Area, the lubricating oil of the low-lying long-pending oil area 13a in oil pocket front end, the low-lying long-pending oil area 13b of oil pocket middle-end and the low-lying long-pending oil area 13c in oil pocket rear end
