Abstract

To increase a cooling performance by preventing a thermostat from hunching regardless of an abrupt change in cooling water temperature in an engine cooling device featured with the thermostat formed by supporting a waxed case with wax, movably according to the expansion and contraction of the wax, on a housing installed on an engine body having a water jacket provided therein. The housing 48 of a thermostat 44 is formed into a tubular shape, and disposed so that the outer peripheral surface thereof comes in contact directly with an engine body 5. A waxed case 53 is fitted to the housing 48 in the state of coming in contact directly with the inner peripheral surface of the housing 48.

The indentation 仃 is a built-in wax. [Knowledgeable Technology] No. Japanese Patent Laid-open No. Hei [Problems to be Solved by the Invention] In the above-mentioned conventional method, the temperature of the thermostat is reduced to m by the cooling water jacket connected to the thermostat. It is assumed that the flange portion of the branch is held between the cylinder head and the suction branch pipe ... The wax in the wax box that can move freely is located at the position of the flange portion. Therefore, the temperature change of the cylinder head has little effect on the wax. The effect of the expansion and contraction of the cooling water depends on the temperature of the cooling water in contact with the butterfly box. The wax expands and contracts, especially based on cooling during warm-up ... The present invention is made by the creator in view of the above problems, and the object of the present invention is to cool the engine which can prevent the operation of the thermostat even if the temperature of the cooling water changes sharply, and can improve the cooling performance of the engine.

The connection pipe 72 for conducting the water chamber 70 between the outlet holes 65 is installed on the top cover 23, and is connected to the cooling water pump 41 through the conduit 73. The μ connection officer 72 is the second, and the function of this embodiment will be described. The outer peripheral surface of the thermostat case 48 of 44 is directly connected to the cylinder head 7 and the wax box 53 with the wax 58 is stored in the thermostat. The inner periphery of the thermostat case 48 is slidably fit into the thermostat case 48 Since the butterfly box 53 and the thermostat shell 48 which are in direct contact with each other are embedded in contact with each other, the heat is transferred to the wax μ by the heat conduction of the cylinder head 7 in direct contact with the two 48 into the cooling water even when the engine is warmed up. The temperature changes sharply. ° ° Therefore, it can also be formed to accurately correspond to the temperature of the cylinder head 7, and the vibration of the thermostat 44 of f 8 can be used to improve the cooling performance. The side wall is provided with an outlet hole 64 ′ connected to the cooling water port and an outlet hole 65 communicating with the radiator 45, and is arranged on a diameter line of the thermostatic casing 48; the above is arranged to switch between the inlet miscellaneous outlet holes 65 The communication sliding case 48 is fitted into a freely sliding state. Straight line: ^ is the aperture 64 and outlet aperture 65 so that the cooling water through the thermostat well :: "in the technology, can reduce the passage resistance of the passage.

Description of the invention (9) In addition, the wax 5 8 can be brought close to the cylinder head 7 to prevent the vibration action of the thermostat 4 4 more effectively, and the cooling performance can be further improved. Also, since the joint surface 4 9 of the cylinder head 7 and the top cover 23 is along the axis of the strange thermostat case 48, and the thermostat case 4 8 is sandwiched between the cylinder head 7 and the top cover 23, it is shortened. The cooling water passage in the thermostat 44 can further reduce the passage resistance, and the thermostat 44 can be miniaturized and assembled on the cylinder head 7. Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and various design changes can be made as long as they do not exceed the scope of the patent application described in the present invention. For example, in the above-mentioned embodiment, although the structure in which the thermostat 44 is mounted on the cylinder head 7 of the main body 5 has been described, the cooling of the cylinder member 6 of the main body 5 can be “widely [effect of the invention] according to the above-mentioned application patent A sharp change in the first temperature of the range can also make the engine the first month, even the temperature of the cold water, thus preventing the strange temperature from positively corresponding to the butterfly energy. The dispatch operation can improve the cooling performance according to the above-mentioned patent application The simplification of the cooling water passage in the thermostat in the second item of the scope, and the invention of the war, because the constant force prevents the vibration of the thermostat from reducing the passage resistance performance of the passage. It can be further improved. Cooling The cooling water path shortened according to item 3 of the above-mentioned patent application can shorten the path of the invention.
