Embodiment Construction
[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] combine Figure 2-6 As shown, the present invention provides a fuel oil pressure stabilizing exhaust device 100. In order to solve the defects in the prior art, the present invention makes the following technical improvements: comprising a tank body 10, and Cover 20, and the floater 30 that is attached to the inner wall of the upper cover 20 and slides on the inner wall of the upper cover 20 along the direction of fuel level rise and fall. The upper cover 20 has a first chamber 21 and a second chamber 22 that are vertically connected and communicated. The body 10 communicates with the first cavity 21, and the first cavity 21 communicates with the exhaust port 211 provided on the upper cover 20, the slider group 40 slidingly connected in th...

The invention discloses a stabilizing and exhausting device for fuel oil. The stabilizing and exhausting device comprises a tank body, an upper cover and a floater, wherein the upper cover is fixedly connected with the tank body, and the floater is fitted to the inner wall of the upper cover and is slidably connected with the inner wall of the upper cover along the rising direction of the fuel oil level. The upper cover is provided with a first cavity and a second cavity which are connected and communicated perpendicularly. The tank body is communicated with the first cavity, the first cavity is communicated with an exhaust port of the upper cover, a slider group slidably connected in the second cavity is sealed in the exhaust port, the floater slides to the greatest distance towards one side of the upper cover under the action of buoyance, and the floater is abutted against the upper cover and sealed in the first cavity. The stabilizing and exhausting device has the stabilizing and exhausting function and is simple in structure, stabilizing and exhausting are integrated and space occupation is reduced.
Description
technical field [0001] The invention relates to the technical field of fluid pressure stabilizing equipment, in particular to a fuel oil stabilizing exhaust device. Background technique [0002] In the test and verification process of automobile engines, it is necessary to use a fuel consumption meter to measure the fuel consumption of the engine. However, the fuel consumption meter uses a mass flow meter measurement principle, which has high requirements for the pressure stability of the fuel. If the pressure is unstable, it will affect The measurement accuracy of the fuel consumption meter, therefore, a pressure-stabilizing exhaust device needs to be added to the fuel pipeline to ensure the accuracy of the measurement results. [0003] The pressure stabilizing exhaust device of the prior art such as figure 1 As shown, it includes a surge tank 1' and an exhaust valve 2' connected in series. The fuel flows in from the oil inlet hole of the surge tank 1' along the flow direc...
