This utility model relates to the field of gearbox top cover technology and discloses a novel gearbox top cover, including a connecting straight pipe. The upper end of the connecting straight pipe is connected to the gearbox cover body by bolts. A nut is threaded onto the axial side wall of the bolts. A filter assembly for filtering grease is provided on the connecting straight pipe. A fixing assembly for clamping and fixing felt is provided on the connecting straight pipe. A discharge assembly for venting steam is provided on the gearbox cover body. Grease is filtered by a filter plate. Because the filter plate is inclined downwards, when there is too much grease on the filter plate, it will flow down due to gravity. When the grease leaves the filter plate, the weight of the filter plate decreases. At this time, the torsion spring will cause the filter plate to vibrate, thereby shaking the grease off the filter plate and preventing the filter plate from being filled with grease, which would affect the filtration effect.

The utility model discloses a pressure-equalizing air distribution disc which is provided with an inner air channel and an outer air channel, the inner air channel extends up and down, the outer air channel is annularly arranged outside the inner air channel, the outer air channel is communicated with the inner air channel through a communication port, a baffle is arranged in the outer air channel, the baffle extends outwards from the upper side of the communication port, and the baffle and the lower wall of the outer air channel are arranged at intervals to form a pressurization space. The baffle is provided with a vertically-extending air passing hole. The baffle is arranged in the outer air channel, the baffle extends outwards from the upper side of the communicating opening and is spaced from the lower wall of the outer air channel to form the pressurizing space, after air flows into the pressurizing space from the communicating opening, one part of the air flows into the position, away from the communicating opening, of the outer air channel towards the front / rear end of the baffle, and the other part of the air flows into the air outlet space through the air hole. The baffle plays a role in depressurizing gas in the gas outlet space, and the baffle plays a role in pressurizing gas, far away from the communicating opening, of the outer gas channel, so that the gas pressure, far away from the communicating opening, of the outer gas channel tends to be consistent with the gas pressure of the gas outlet space, and pressure-equalizing gas outlet is achieved.

The invention discloses a multi-cylinder engine air entrapment direct injection common rail device, and belongs to the technical field of engine fuel injection. The device comprises an oil inlet shell, an air inlet shell, a fuel oil common rail pipe, an oil-gas integrated shell, a fuel oil injector, an oil-gas mixed injector, a pressure regulating valve and an air release valve. Wherein the fuel oil common rail pipe is connected with the oil inlet shell to form an oil supply channel, and the oil-gas integrated shell is connected with the gas inlet shell to form a gas supply channel; the fuel injector communicates with the oil supply channel, the oil-gas mixing injector communicates with the gas supply channel, and an outlet of the fuel injector communicates with a premixing cavity of the oil-gas mixing injector. The pressure regulating valve is used for regulating pressure of fuel oil and gas, and the gas release valve is used for releasing redundant gas to stabilize gas pressure.
