Description

Suction filter with buffer memory function

Technical Field

The utility model relates to a suction filter, in particular to a suction filter with a buffer function.

Background

Suction filters refer to devices that utilize a vacuum to force a liquid in a fluid through a filter paper to separate solid particles in the fluid. A filter cavity is formed in the suction filter, and filter paper is arranged in the filter cavity. When the filter is used, the vacuum pump is arranged at the outlet of the suction filter, fluid can be pumped into the filtering cavity from the inlet of the suction filter through the vacuum pump, filtered by the filter paper and flows out from the outlet of the filter, and solid particles in the fluid are trapped by the filter paper, so that the fluid is filtered. Currently, there are flat-type, integrated-type and cylindrical-type automatic transmission suction oil filter structures, wherein when a transmission oil pump is operated, a flat-type suction filter works, a liquid inlet of the suction filter is immersed in oil, and an oil pump is installed at a liquid outlet of the suction filter to generate negative pressure so as to realize suction of the oil. The oil enters the filtering cavity of the suction filter from the oil suction port of the suction filter, and after being filtered by filter paper in the filtering cavity, the oil flows out from the liquid outlet and enters the hydraulic system through the driving of the oil pump.

The motorcycle can produce great rocking when special road conditions are driven, leads to the fluid of gearbox bottom to make a round trip to shake, leads to the unable stable oil absorption of original suction filter.
