Abstract
A cooling circuit arrangement for a multicylinder internal combustion engine with V-shaped cylinder banks and cooling jackets which surround the cylinder banks and which are provided with cooling liquid by a pump arranged between the two cylinder banks on one of their face sides is disclosed. The pressure-sided connection of the coolant pump, arranged on the one face side of the two cylinder banks, is connected by a coolant pipe to a distributor pipe, arranged on the other face side of the cylinder banks, for the purpose of feeding cooling liquid. A return flow chamber for the coolant from the cooling jackets is arranged between the two cylinder banks adjacent to the pump housing. In this manner the space, existing between the two cylinder banks, is utilized for a part of the coolant arrangement so that the internal combustion engine exhibits a compact design.
