Embodiment Construction
[0012] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.
[0013] according to figure 1 , figure 2 As shown, the respirator inner partition (1) and the starter bracket (2) form the first pressure chamber, and the first pressure chamber communicates with the crankcase (9) through the hole on the respirator inner partition (1) , the respirator cover (3) and the starter bracket (2) form the second pressure chamber, the first pressure chamber communicates through the ventilation pipe (11) of the starter bracket (2), when the internal pressure of the crankcase (9) When the pressure is higher than the ambient pressure, the pressure pushes the spring leaf (5) outwards, and the gas enters the second pressure chamber, and then the air inside the crankcase (9) is renewed through the...

An electric-start engine respirator structure is mainly composed of an inner partition plate of the respirator, a starter bracket, a respirator cover, a respirator cover gasket, a spring sheet, a pressure plate, a fastener, a ventilation pipe, and a respirator gasket. , the spring plate is installed under the pressure plate, and the fasteners fasten the pressure plate and the spring plate to the starter bracket together; a ventilation pipe is provided in the respirator cover; the respirator cover and the respirator cover gasket are installed together to On the starter bracket; two breather gaskets are assembled on both sides of the inner partition plate and assembled on the crankcase together with the starter bracket. The invention can simplify the structure of the respirator, and at the same time, it can achieve the function of the respirator, and reduce the cost of product distribution.
Description
technical field [0001] The invention relates to the structure of an electric starter engine respirator, which belongs to the field of machinery. Background technique [0002] As a necessary and unique structure of the engine, the respirator is very important and indispensable. For adjusting the internal pressure of the crankcase, adjusting the pressure difference between the inside and outside of the engine body, discharging part of the combustion exhaust gas with a high temperature, and inhaling part of the fresh air, it can effectively reduce the At the same time, the internal temperature of the crankcase can prolong the lubricating effect of the engine oil. At present, domestic engine breathers are usually equipped with two pressure chambers for cost considerations, and the pressure chambers are adjusted by a spring plate with a check valve function. When the internal pressure of the crankcase is higher than the ambient pressure, the pressure will be adjusted by the sprin...
