Abstract
A compact water cooled internal combustion engine for a vehicle wherein a water pump operated by a pump driving shaft is arranged on a crankcase cover for covering a lateral side of a crankcase, such that an axis of rotation of the water pump is coaxial with the pump driving shaft. A case member that forms a pump case of a water pump, together with a crankcase cover, and that rotatably supports a pump shaft of the water pump, is attached on an inner surface side of the crankcase cover.

A water cooled internal combustion engine for a vehicle comprising:
- a crankcase constituting a portion of an engine main body mounted on a vehicle body frame, and rotatably supporting a crankshaft;
- a crankcase cover for covering a lateral side of the crankcase, said crankcase cover being attached to the crankcase;
- a pump driving shaft operated by power transmitted from the crankshaft, said pump driving shaft being rotatably supported on an axis parallel to the crankshaft by the crankcase;
- and
- a water pump to be driven through the pump driving shaft, having an axis of rotation coaxial with the pump driving shaft and being arranged on the crankcase cover;
- wherein a case member forms a pump case of the water pump, together with the crankcase cover, and rotatably supports a pump shaft of the water pump, said case member being attached on an inner surface side of the crankcase cover.
A water cooled internal combustion engine for a vehicle comprising:
- a crankcase for rotatably supporting a crankshaft;
- a crankcase cover operatively connected to said crankcase for covering a lateral side of the crankcase;
- a pump driving shaft operatively connected to the crankshaft, said pump driving shaft being rotatably supported on an axis parallel to the crankshaft by the crankcase;
- and
- a water pump operatively connected to the pump driving shaft, said water pump having an axis of rotation coaxial with the pump driving shaft and being arranged on the crankcase cover;
- wherein a case member forms a pump case of the water pump, together with the crankcase cover, and rotatably supports a pump shaft of the water pump, said case member being attached on an inner surface side of the crankcase cover.
