が防止される。(Prior art) Conventionally, in order to accelerate the temperature rise of lubricating oil during warm-up operation, the oil pan was divided into two chambers, a main chamber and a sub-chamber, and lubricating oil was supplied from the main chamber to the engine. At the same time, when the lubricating oil temperature is low, the lubricating oil is prevented from flowing between the two chambers, and when the lubricating oil is heated by the engine and reaches an appropriate temperature, the lubricating oil is allowed to flow between the two chambers. A device that has been used for this purpose is known. For example, in the device disclosed in Japanese Utility Model Application Publication No. 58-2310, a main chamber (main tank) and an auxiliary chamber (sub-tank) are formed by a partition plate that partitions the interior of the oil pan into left and right sides. At least two communication portions each have a valve that closes when the temperature is low and opens when the lubricating oil is heated to a predetermined temperature or higher. According to this device, during warm-up operation when the lubricating oil temperature is low, communication between the main chamber and the auxiliary chamber is completely cut off, and only the lubricating oil in the main chamber is supplied and circulated to each part of the engine. This accelerates the temperature rise of the lubricating oil, and when the temperature of the lubricating oil rises above a predetermined temperature, the above-mentioned valves are opened and the main chamber and auxiliary chamber communicate with each other, allowing the lubricating oil to flow in both directions between the two chambers. This prevents the lubricating oil from becoming abnormally high in temperature and from deteriorating.

る。 However, in this device, the main chamber needs to have a sufficient capacity to store the necessary amount of lubricating oil during warm-up operation. Therefore, in order to further accelerate the temperature rise of the lubricating oil during warm-up, the volume of the main chamber is reduced, and a communication port that is always open is provided at one point on the partition plate between the main chamber and the sub-chamber. It is conceivable to provide a valve at another location on the plate that closes during warm-up operation and opens when the lubricating oil temperature rises to a predetermined temperature or higher. In this way, during warm-up operation, lubricating oil is sent from the main chamber to each part of the engine, and lubricating oil is supplied from the sub-chamber to the main chamber through the always-open communication port, but when the above-mentioned valve is closed. This prevents the lubricating oil from flowing out from the main chamber to the auxiliary chamber, and promotes a rise in the temperature of the lubricating oil in the main chamber. However, when doing this, the viscosity of the lubricating oil increases when the temperature of the lubricating oil is extremely low, such as when starting in a cold region. It becomes difficult for oil to flow in.

げられないようにするためである。 As shown enlarged in FIG. 3, the valve device 11
The warm thermostat 12 is a valve that closes until the temperature of the lubricating oil is raised to a certain high set temperature (for example, about 60°C) during warm-up operation, and opens when the temperature is higher than the set temperature on the high temperature side. In addition, set temperature on the low side corresponding to extremely cold times (e.g. around 0℃)
A cold thermostat 20 is provided as a valve that closes at the following times and opens at or above the set temperature on the low temperature side. The warm thermostat 12 opens and closes one opening 10a of the communication portion 10, and includes a valve body 14 fixed to the wax case 13, a fixed frame 15 attached to the partition plate 4b, and a valve seat 16.
a plunger 17 which is inserted into the wax case 13 and whose tip abuts against the fixed frame 15; and a spring 18 which biases the valve element 14 in the valve closing direction.
It is equipped with And the above wax case 1
3 is sealed with wax that melts at a relatively high temperature of about 60°C, and when this wax is in a solid state, the valve element 14 contacts the valve seat 16 to close the opening 10a, and the wax melts. When it melts and expands, the plunger 17 is pushed out, thereby moving the wax case 13 and the valve body 14 to open the opening 10a. Further, the cold thermostat 20 opens and closes the other opening 10b of the communication section 10, and the wax case 21
The wax case 1 is inserted into this wax case 21 and has a warm thermostat 12 at its tip.
3, a valve body 24 attached to the protrusion 23 at the end of the wax case 21 and facing the opening 10b, and biasing the wax case 21 and the valve body 24 in the valve opening direction. It is equipped with a spring 25. Wax that melts at a low temperature of about 0° C. is sealed in the wax case 21, and when the wax is in a solid state, the valve body 24 moves away from the periphery of the opening 10b to open the opening 10b. When the wax melts and expands, the plunger 22 is pushed out and the wax case 21 and valve body 24 are pushed out.
moves to close the opening 10b. The valve body 24 of the cold thermostat 20 is slidable relative to the protrusion 23 of the wax case 21, and is held in place by a spring 26 provided between the valve body 24 and the wax case 21. It is held at the tip position of 23.
This is because when the warm thermostat 12 is activated after the cold thermostat 20 is activated and the valve body 24 is brought into contact with the periphery of the opening 10b, the warm thermostat 12 is activated. Tatsuto 12
This is to allow the wax case 21 of the cold thermostat 20 to move when pushed by the wax case 13 of the cold thermostat 20, so that the operation of the warm thermostat 12 is not hindered.

を開くこととなる。 In the structure of this oil pan, as shown in FIG. 4, which shows the relationship between the lubricating oil temperature and the opening degree of the communication portion 10, the lubricating oil temperature is set at a low-temperature set temperature of about 0°C.
When the temperature is below T1 , the state shown in FIG. 3 is reached, and the cold thermostat 20 opens the opening 10b. Further, in the range between the low-temperature set temperature T 1 and the high-temperature set temperature T 2 of about 60° C., the cold thermostat 20 is closed and the warm thermostat 12 is kept closed. Therefore, the communication part 1
Both openings 10a and 10b of 0 are closed. Further, when the high temperature side set temperature T2 or higher is reached, the warm thermostat 12 is activated and the opening 10a is activated.

止される。 Therefore, when the engine 1 is started in extremely cold weather below the low-temperature set temperature T1 , as the lubricating oil 3 in the main chamber 5 is supplied to the engine 1, the communication port 9 and the opening 10b of the communication portion 10 are The lubricating oil 3 is smoothly supplied from the auxiliary chamber 6 to the main chamber 5 through. In other words, the main chamber 5 is formed in advance to have a small capacity, and if the main chamber 5 is not sufficiently supplied with lubricating oil, the lubricating oil supplied to the engine 1 will be insufficient and problems such as seizure will occur. In addition, in extremely cold weather, the viscosity of the lubricating oil is high, so it is difficult for the lubricating oil 3 to flow into the main chamber 5 only through the communicating port 9, which is always open. By being opened, lubricating oil easily flows into the main chamber 5, and a lack of lubricating oil in the engine 1 is reliably prevented. Also, the lubricating oil temperature is set at the low temperature side T 1
During warm-up operation in a state where the temperature is above and below the high-temperature set temperature T 2 , lubricating oil 3 is supplied from the auxiliary chamber 6 to the main chamber 5 only through the communication port 9, which is always open. In this case, since the viscosity of the lubricating oil 3 is low, it can sufficiently flow into the main chamber 5, and moreover, the lubricating oil 3 that is returned to the main chamber 5 after lubricating each part of the engine and being heated is Since it is prevented from flowing into the chamber 6, the temperature of the lubricating oil 3 in the main chamber 5 can be raised efficiently. Furthermore, the lubricating oil temperature is set at the high temperature side.
When the temperature exceeds T 2 , the lubricating oil 3 freely flows between the main chamber 5 and the auxiliary chamber 6 through both the communication port 9 and the opening 10a of the communication portion 10, and the lubricating oil temperature during normal operation decreases. Abnormal rise and deterioration of lubricating oil are prevented.

る。 FIG. 5 shows another embodiment of the invention. In this embodiment, a partition member 4 that partitions a main chamber 5 and an auxiliary chamber 6 is used.
One side partition plate 4b is provided with a communication section 30 that is opened and closed by a valve device consisting of one solenoid valve 31 that doubles as a valve that opens when the temperature is high and a valve that opens when it is extremely cold. A pair of temperature switches 32 and 33 are installed in the main chamber 5, which operate according to the temperature of the lubricating oil in the main chamber 5. This pair of temperature switches 32,3
3 and the solenoid valve 31 are connected in series to a power source 34. As shown in FIG. 6, the first temperature switch 32 is turned on when the low-temperature side set temperature T1 or higher, and the second temperature switch 33 is turned on at the high-temperature side set temperature.
The solenoid valve 31 is configured to turn on at T 2 or less, and accordingly, the solenoid valve 31 closes the communication section 30 when both temperature switches 32 and 33 are on, and opens the communication section 30 at other times. . The structure of other parts is almost the same as that of the first embodiment.

される。 In this embodiment as well, the communication port 9, which is always open, is used in extremely cold conditions when the lubricating oil temperature is below the low-temperature set temperature T1 and during normal operation after warming up when the lubricating oil temperature is higher than the high-temperature set temperature T2. In addition, the communication portion 30 is opened,
Furthermore, during warm-up operation when the lubricating oil temperature is between the two set temperatures T 1 and T 2 , the communication portion 30 is closed, so that the same effect as in the first embodiment is achieved.
