Abstract
A casing structure of a water-cooled internal combustion engine includes a casing member defining an oil pump chamber and a water pump chamber. A rotor of an oil pump is inserted into the oil pump chamber and an impeller of a water pump is inserted into the water pump chamber. A cover member covers the casing member.
Claims19
A casing structure of a water-cooled internal combustion engine comprising:
- an oil pump including a rotor inserted into an oil pump chamber formed on a casing member that covers a first end of a crankshaft supported by a crankcase;
- and
- a water pump including an impeller inserted into a water pump chamber formed on the casing member;
- and
- a cover member covering the oil pump chamber and the water pump chamber of the casing member.
2 more elements
A casing structure of a water-cooled internal combustion engine comprising:
- a casing member received on an end of a crankcase of the engine;
- an oil pump chamber for an oil pump at least partially defined by the casing member, the oil pump chamber receiving a rotor of the oil pump;
- a water pump chamber for a water pump at least partially defined by the casing member, the water pump chamber receiving an impeller of the water pump;
- and
- an elongated oil tank chamber at least partially defined by the casing member, a portion of the oil tank chamber extending between the oil pump chamber and the water pump chamber.
2 more elements
A casing structure for a water-cooled internal combustion engine having a crankcase, the casing structure comprising:
- a casing member located at an end of the crankcase;
- an oil pump chamber including an oil pump chamber recess defined by at least one side wall of the casing member and an oil pump chamber front wall of the casing member, the oil pump chamber front wall located opposite the crankshaft end, the crankcase end enclosing the oil pump chamber recess to define the oil pump chamber with the casing member;
- and
- a water pump chamber including a water pump chamber recess defined by at least one side wall of the casing member and a water pump chamber front wall of the casing member, the water pump chamber front wall located opposite the crankcase end, the crankcase end enclosing the water pump chamber recess to define the water pump chamber with the casing member.
