Claims14
An oil pan provided with a first chamber which is open to an object lubricated by oil and in which an oil suction opening connected to an oil pump for delivering oil to the lubricated object is arranged at a bottom part, a second chamber adjacent to the first chamber and a partition provided between the first chamber and the second chamber, comprising:
- a thermo valve that is provided to the partition and makes the first chamber and the second chamber communicate according to a temperature of oil;
- a communicating opening provided to the partition so that the bottom part of the first chamber and a bottom part of the second chamber ordinarily communicate separately from the thermo valve and formed so that oil can flow from the first chamber into the second chamber when the oil is discharged outside from the second chamber;
- and
- a shielding member provided to the bottom part of the first chamber between the communicating opening and the oil suction opening.
An oil pan provided with a first chamber open to an object lubricated by oil, a second chamber adjacent to the first chamber and a partition provided between the first chamber and the second chamber and having a concave part forming the first chamber, comprising:
- a communicating opening which is a through hole provided at a bottom of the concave part of the partition equivalent to a lowest position of a bottom face of the first chamber and which is formed so that oil can be discharged downward from the first chamber into the second chamber when the oil is discharged outside from the second chamber;
- a lid member arranged so that the lid member can close the communicating opening from an outside and an downside of the concave part;
- a float member made of a material having a smaller specific gravity than the oil and arranged inside the concave part opposite to the lid member with the communicating opening between the float member and the lid member;
- and
- a coupling member that pierces the communicating opening and couples the lid member with the float member.
An oil pan provided with a first chamber open to an object lubricated by oil in which an oil suction opening connected to an oil pump for delivering oil to the lubricated object is arranged at a bottom, a second chamber adjacent to the first chamber, a partition provided between the first chamber and the second chamber, a communicating opening provided to the partition so that the bottom of the first chamber and the second chamber communicate, and a shielding member provided to the bottom of the first chamber between the communicating opening and the oil suction opening,
- wherein the communicating opening is formed at an end part in a top view of the first chamber.
