A filter and engine assembly

Abstract

The invention relates to the field of engine assemblies, and specifically discloses a filter. The filter includes a filter tank, a filter chamber is provided inside, and an oil inlet and an oil outlet connected to the filter chamber are provided on it; a filter element , installed in the filter cavity, with a Installation hole; middle pipe, which is equipped with an oil guide channel inside. The middle pipe is partially located in the installation hole. One end of the bottom is sealingly connected to the filter tank. Only one end of the top of the middle pipe is provided with a through hole. Both ends of the through hole are connected to the filter tank respectively. The cavity is connected to the oil guide channel, and the oil guide channel The pipe is connected to the oil outlet, so that the oil in the filter tank can only flow out of the oil outlet through the through hole on the top of the middle pipe; the first one-way valve is installed at the oil inlet, and the oil can enter through the first one-way valve into the filter chamber, so that the engine stops The oil behind the engine will not flow back to the oil pan. Combined with the middle pipe, it can ensure that after the engine is stopped, the oil in the filter tank below the through hole will not flow out. When the engine is started again, the oil in the filter tank will be filled quickly to ensure movement. Lubrication of parts.

Description

technical field [0001] The invention relates to the field of engine assembly, in particular to a filter and the engine assembly. Background technique [0002] The main function of the oil filter is to filter out metal and non-metal impurities, colloid and other harmful substances in the oil through the filter element, so as to ensure the cleanliness of the oil in the lubricating parts, reduce wear and prolong the service life of the machine. [0003] However, the existing oil filter has the following problems: [0004] 1) When the engine is stopped, especially for the oil filter whose oil outlet is set under the filter canister, the oil in the filter canister will be empty, and the oil needs to be refilled when restarting. The oil can enter the lubricating oil passage through the oil outlet to lubricate the moving parts, resulting in a short-term lack of oil for the moving parts, especially when the engine is frequently started and stopped, it will aggravate the wear of the...

AI Technical Summary

Problems solved by technology

[0008] One object of the present invention is to provide a filter to solve the problem of the oil filter in the prior art. When the engine is stopped, the oil in the filter tank will flow out of the filter tank, causing the moving parts to be short-lived when the engine is started. Lack of oil, easy to cause wear problems

[0009] Another object of the present invention is to provide an engine assembly to solve the problem that the oil in the filter tank of the oil filter in the prior art is easy to flow out after the engine stops, and it takes time to remove the oil filter after the engine is restarted. The filter canister is filled with oil, during which time it is easy to cause wear problems of moving parts
