Saw Slot Coolant Flow Orifice

摘要

The present invention provides a cylinder block(l) with a sawslot(2) to improve coolant flow by placing an orifice drill hole (3) connecting the sawslot to a low pressure coolant(4) reservoir found in the cylinder head(5). The orifice drill hole is also paired with a flow obstruction(6) to prevent high pressure coolant(7) back flow from the opposite side of the cylinder block coolant jacket. The head gasket(8) requires a mating hole for the coolant to pass through into the orifice drill hole. The combination of parts improve the coolant flow between the cylinders of a cylinder block for an internal combustion engine.
