Abstract

The invention discloses an oil pressure switch, including a shell (1), a plug (8) which forms a seal cavity with the shell (1), a division sheet which divides an upper part of the cavity into a switch chamber and is communicated with an oil pipe at a lower end of the division sheet, a fixed contact which is fixed in the switch chamber, a movable contact which can move along the division sheet and is contacted with the fixed contact, an elastic piece which is arranged between the movable contact and an insertion sheet of the plug (8), and double metal sheets (9) which are arranged between the elastic piece and the insertion sheet. When the temperature in the switch chamber is lower than a set value, a lower metal plate of the double metal sheets (9) protrudes upward, and when the temperature in the switch chamber is higher than the set value, the lower metal plate protrudes downward, and the thermal expansion coefficient of an upper metal plate of the double metal sheets (9) is smaller than that of the lower metal plate. The oil pressure switch effectively solves problems that the performance of the switch chamber of the oil pressure switch is unstable and the like. The invention also discloses an explosive motor including the abovementioned oil pressure switch.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an engine oil pressure switch of the internal combustion engine. Furthermore, the present invention also relates to an internal combustion engine comprising the above-mentioned engine oil pressure switch. Background technique [0002] The role of the oil pressure switch in the engine lubrication system is to sense the lubricating oil pressure of the engine. When the oil pressure is lower than the set value, the oil pressure switch is connected to the circuit of the oil warning light, and the oil warning light is lit to notify the driver to check the remaining lubricating oil in time. Whether the amount and the lubrication system are normal, to avoid damage to the engine due to poor lubrication. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a typical engine oil pressure switch in the prior art. [0004] At present, the oil pressu...
